General Fitting Instructions for rear coil spring vehicle. These instructions are only a guide line to fitting suspension kits and some parts and items may vary slightly. Only a qualified mechanic should attempt to fit vehicle suspension.

LOCKTITE MUST BE USED ON ALL SUSPENSION PARTS 1. Starting with the vehicle on level ground, bump stop heights must be taken prior to disassembling the vehicle. Please fill out the vehicle fitment form clearly and correctly, if you have not received a fitment form please contact Superior Engineering for a copy. Warranty will not be accepted without before and after measurements! Front and rear is required for warranty purposes and if these measurements are not recorded you will not get warranty if there is a problem. Image 1 shows were to place the tape measure inside the front coil and measure straight underneath the factory bump stop to the diff striker pad, check the bump stop is not broken. Image 2 shows how to measure under the rear bump stop to the striker pad.

2. Remove the front and rear sway bar links prior to lifting the vehicle on the hoist . Image 3 is the rear and image 4 is the front

3. Place the vehicle on the hoist and now remove all 4 tires. The rear tail shaft of Nissan Patrols need to be removed and turned around to allow for more clearance at the cross member. 2 inch lifts this does not need to be done. 3-5 inch lifts just turning the driveshaft should be enough but you need to check at full drop after the suspension is fitted if the cross member hits the tail shaft, if it does you will need to modify the cross member , instructions for this can be supplied if requested. All 6-7 inch kits need the cross member to be modified. Image 5 shows standard configuration and image 6 shows the extra clearance gained

Image 4 Image 6 extra clearance gained here 4. Using a gearbox jack support the diff underneath for when you remove the shocks, but first remove the proportioning valve bracket from the top of the diff at the rear and replace with the supplied bracket, also remove and replace the brake line and diff breather hose. With the diff supported, slightly lift the diff upwards and now remove the shocks, coils and upper control arms and rear pan hard rod. Image 7

Image 7 5. Adjust the upper control arms centre – centre as follows as starting point 382mm – 3 inch lifts / 374mm – 4-5 inch lifts / 384mm 6-7 inch lifts Fit the upper control arms to the diff and the upper chassis mounts, note the control arm thread faces forwards and upwards, stickers face outwards, only loosely fit the bolts and nuts DO NOT TIGHTEN . See Image 8 and Image 8A

Image 8 image 8A 6. If coil drop out cones have been included in the kit this is the best time to install them. A welder is needed if they are a weld in item, Simply hold the coil drop out cone up under the chassis where the coil would locate, the cone will be a nice fit when in position. Only 3 small 20mm welds need to be done , there is no need to weld any more than that. See image 9

7. Prior to fitting the rear coil springs in place , you must trim off approx 10-12mm from the rear of the diff bump stop striker pad, this allows enough room for the shocks to clear during articulation. BE CAREFULL NOT TO CUT THE BRAKE LINES See image 10.

Many coils have a passenger and drivers side, most vehicles have the taller coil on the drivers side, please check. Nissan is usually the same height on both rear but not always. If you have air bags this is the time to install them, they have separate instructions. Most Superior Engineering Kits have coil retainers, if so fit these as well. With the coil retainers make sure that the retainer is not going to make contact with the rear shock or brake line at any time of articulation. Retainers can only be fitted and tightened with the coil properly seated in the diff locater. See Image 11

image 10 Image 11 Trim striker pad rear only 8.Now that the coils, retainers, drop out cones, brake bias bracket and upper control arms are in place you can fit the rear shocks, you may need to use the gearbox hoist to lift the diff enough to fit the shocks, It is easier to fit the shocks with the weight of the vehicle on the suspension as the shock mounts will be in a more correct angle . Loosely fit the rear panhard rod , do not worry about adjusting it at this point of the fit up If you have lower control arms do not fit them yet, it is easier to fit them later. Image Below shows the rear end assembled properly.

9. Fit the tires and the vehicle may be placed on the ground at this point with the full weight on the coils. Firstly check the pinion angle is correct, if the angles are within 1 degree than the control arms may be tightened to specifications ( use locktite). To check the pinion angle see drawing below, the angle of the differential must be the same as the transfer case, this is done by shortening or lengthening the upper control arms. NOTE: if you are using lower control arms it is recommended to fit them prior to adjusting the pinion angle. NOTE: if drop boxes or gearbox spacers are used they must be fitted prior to adjusting the pinion angle. ( separate instructions supplied )

Adjustment of the rear panhard rod is done by using a straight edge such as a spirit level or piece of flat steel and place it against the outside of the tire , measure to the chassis and record this measurement for reference. Now measure the other side the same way and record this measurement. If the drivers side is approx 400mm and the passenger side is approx 380mm you subtract the 2 measurements from each other and divide by 2. Add this measurement (10mm) to the shorter side and this is the approx amount to wind out the panhard rod. (390mm) THIS IS ONLY TO SHOW HOW TO DO THE EXERCISE, DO NOT USE THESE MEASUREMENTS. NOTE: The Lower panhard rod washer faces outwards as shown, do not have it facing inwards. See Image 13

image 13 see how the washer cups away from the diff .

image 14 image 15 Drivers side measured 400mm , passenger side measured 380mm = 20mm difference divide by 2 = 10+380mm means you adjust the panhard rod to 390mm , refit and re measure to check it is correct. If the measurement is equal both sides then apply locktite and tighten to specifications. 10. If lower control arms are to be fitted please read . Take note that the steel bushes are welded onto the lower control arms on an angle as the Mounts are narrower at the diff than the chassis mounts. See image below and image 16 We try to always have the stickers facing forwards and outwards but please check prior to fitting the control arms.

Image 16 After the lower control arms are fitted it is always recommended to recheck your pinion angle is correct. 11. All bolts can now be tightened in the rear suspension. It is recommended to recheck all bolts are tight and panhard position is still correct at approx 1000klm’s

If only the rear suspension is being fitted than re measure the bumpstop heights and record, if the front is to be fitted with new suspension wait until the front is complete before taking final measurements. When only the rear suspension is being fitted, then bleed the brakes to complete. 12. If fitting drop boxes carefully read drop box instructions. 13. If fitting caster bushes carefully read caster bush instructions. 14.If fitting Caster plates carefully read caster plate instructions.

15. If radius arms are to be fitted either Super Flex or drop radius arms read further.

Super flex arm / Drop radius arm fitting instructions If you are fitting coils Radius arms can be fitted either before or after the coils are fitted .

1. Start with the vehicle on a hoist and loosen 4 x M16 bolts that hold the factory radius arm to the diff, do not remove these bolts yet, loosen the rear M14 nut at the rear of the factory radius arm. Image D

Image A

Loosen

4 bolts holding the radius arms to the diff as well as the 2 rear Radius arm nuts in the chassis.

Image C ( passenger side)

Image D ( rear radius arm nut – 1 either side )

2. Remove the tie rod from behind the diff. 3. Lower the vehicle on the ground, fitting radius / super flex arms can be performed on a hoist but for anyone who has not done this procedure it is recommended to do it on the ground.

4. Remove the sway bar bolts from the radius arm, if you are not refitting the sway bars to your arms remove the brackets from the chassis as well. See Image E

Image E Remove 2 bolts for sway bar links as well as the link and sway bar bracket on the chassis. If you are retaining sway bars you may need to use different length sway bar links , Superior Engineering will be able to discuss this. NOTE: Using sway bars with drop radius or Super flex the arms will make contact with the sway bar chassis mount on up compression. It is adviseable to remove the whole sway bar assembly prior to 4wding or going offroad. Super flex and Radius arms do not come standard with sway bar holes or ABS holes ,they must be prior ordered. 5. If you have ABS you will also need to remove the bolts that hold the lines to the radius arms 6.Apply the handbrake to the vehicle and chock both front wheel so as they cannot move. 7. Starting on the driver’s side remove both M16 bolts holding the radius arm in the diff mounts, now remove the nut from rear of the radius arm. At this point if you pry the radius arm downwards at the front so it is now out of the diff you can pull the factory radius arm forwards and out, The taller the vehicle is the harder it is to remove the radius arm. On the passenger side remove the Front Bolt ONLY while leaving the rear nut and rear M16 bolt in place.

8. Once the original drivers side radius arm is out,you will need to fit the factory steel washers and either use the original “mushroom bushes” or �t new items. Image F shows the correct fitment of the washers, bushes and nut.

Image F Apply anti-seize here

Choose the correct side radius arm or super flex arm, generally the Superior Engineering logo will be facing outwards . If it is a Super flex Kit the Full size arm goes on the drivers side. Apply anti seize to the thread of the new radius arm, fit the factory steel washer onto the radius arm . Push one rubber mushroom bush into the chassis hole from the front and one from the rear. Push the radius arm into the “mushroom bush” taking care not to push out the rear “mushroom “ bush. Place the steel washer in place with the smaller hole followed by the supplied Locknut and loosely tighten, Push the radius arm up into the diff and fit both front M16 x 90mm bolts into the radius arm and diff , DO NOT TIGHTEN YET. It is sometimes made easier to use a jack under the pinion to adjust the pinion angle accordingly to make the bolt holes line up better. 9.Now that both M16 x 90mm bolts are in place on the driver’s side and the rear radius arm bushes , washers and nut are loosely installed you can remove the passenger side standard radius arm . This is done the same as you did the driver’s side, but you can leave all the bolts in the Driver’s side. 10. If it is Drop radius arms you are fitting than install the same as the driver’s side. 11. If Super Flex arms have been chosen then install the short super flex arm into the chassis, and loosely tighten the rear nut onto the arm.

Adapter plates x 2 M16 Bolts x 100mm M14 x 100mm bolt Super flex arm rear nut

11. With the Super Flex Arm now pushed in place on the passenger side lift up the arm to be in position in the diff mounts, working from the inside hold up one Adapter plate on the inside of the diff plate and insert one M16 x 100mm bolt in the top of the adapter plate, through the super flex arm and fit the outside adapter plate and nut. Position the super flex arm so as the M14 x 100mm bolt goes through the same plates and the same arm. (Bottom rear ) Now fit the 50mm x 21mm OD spacer in the front of the diff , use the M16x100mm bolt to secure.

The 3 images below shows the plates fitted to a bare diff to get the understanding of how the plates fit up.

50mm x 21mm OD spacer

The 3 above images shows the Super flex arm fitted in between the adapter plates. 12. Now that you have the super flex or radius arms in position you can tighten all the bolts securing the Radius arms (USE LOCKTITE)

13. If sway bars are to be used refit the sway bar bolts and assembly opposite to the removal. 14. Refit the Tie rod opposite to removal. (If you are doing a full suspension change than it is recommended to leave of the tie rod for the rest of the fitting)

15. If you have ABS you must bolt on the ABS lines to the top side of the radius or super flex arms. NOTE: ABS LINES HOLE DO NOT COME STANDARD AND MUST BE ASKED FOR DURING THE ORDERING PROCESS.

The image shows Super Flex Arms with the full size arm on the driver side and the short arm with adapter plates on the passenger side. 16. Recheck all the bolts and nuts are tightened to specifications and test drive. 17. Make sure you have recorded your Bump stop heights !

Fitting of front Suspension Components. Make sure you have bumpstop measurements before after the lift is performed, warranty will not be accepted without them! 1. Measure and record the before and after measurements

The image shows were to place the tape.

2. Raise the vehicle on the hoist. 3. Place a gearbox Jack underneath the diff to support it during the suspension change. 4. Remove the Damper (steering stabilizer)

5. Remove the Panhard Rod

6. Remove the Tie Rod as it will make some of the fitting process easier, if it is not already removed. 7. Remove the 2 Shock Absorbers

8. Remove the 2 coil springs from the front end.

9. Remove the Brake line, and refit the new supplied brake line, it is recommended to undo the top connection first and fit the brake line their first, then remove the fitting on the diff and tighten the new brake line, this allows the brake fluid to flow down the brake line and will stop a lot of excess air in the line.

10. Fit the new coils into position, the smaller wind of the coil goes down onto the diff housing. Check that the taller coil is on the driver’s side, sometimes this can be marked as “driver ’s side”. If you are unsure place both coils next to each other and chose the taller coil for the driver ’s side. The coils must be properly located in the top chassis coil mount as the coils are top flat on top.

11. Fit the panhard rod in position, do not tighten yet. The curve in the panhard is fitted on the diff as pictured below. 12. Loosely fit the drag link and only do nuts up finger tight. On the heavy duty 4140 competition Drag link the tightening bolts must face away from the lower knuckle , if it is not on full right hand down turn the bolt will hit the panhard bolt causing damage. See picture below. DO NOT fit damper yet.

The image above shows the panhard rod and drag Link properly fitted to the vehicle. 13. The shocks can now be fitted , with the diff hanging and not having the weight of the vehicle compressing the coils you may not be able to fit the shocks fully, if this is the case you will need to lower the vehicle onto the ground. If using SRC remote res shocks please read instructions on fitting

14. If the vehicle is still on a hoist, fit the tires and lower fully onto the ground. Adjustment of the Front panhard rod is done by using a straight edge such as a spirit level or piece of flat steel and place it against the outside of the tire , measure to the chassis and record this measurement for reference. Now measure the other side the same way and record this measurement. If the driver’s side is approx 350mm and the passenger side is approx 370mm you subtract the 2 measurements from each other and divide by 2. Add this measurement (10mm) to the shorter side and this is the approx amount to wind out the panhard rod. (360mm) THIS IS ONLY TO SHOW HOW TO DO THE EXERCISE, DO NOT USE THESE MEASUREMENTS. NOTE: The Lower panhard rod washer faces outwards as shown , do not have it facing inwards.

see how the washer cups away from the diff .

drivers side passenger side

refit and re measure to check it is correct. If the measurement is equal both sides then apply locktite and tighten to specifications.

15. Now that you have the Diff central to the car you can adjust the drag link correctly. First step is to ensure the wheels are straight ahead. Second step is to remove the top of the drag link out of the pitman arm. In the cab of the vehicle turn the steering wheel fully to the left, count exactly how many times you turn the steering wheel to go to full right turn. Now turn back half that amount. THIS IS CENTRAL IN THE BOX. If the steering wheel is not straight you will have to remove the wheel and refit straight. If the vehicle is new you can disregard the last step as we know the steering wheel will not have been removed and should be central. Evenly adjust the drag link out to the desired length so the drag link now fits into the two taper holes.

Fit the nuts into place and tighten and secure with split pins, as well as fitting the bolts into the clamps of the tie rod end. Fit Grease Nipples (do not over tighten as they are only 6mm) and add ONLY ONE PUMP of grease, anymore and the rubber boot may tear from excessive pressure. NOTE : some other types of our drag links and tie rods do not use the clamp style ends.

16. Cycle the steering from left to right to check there is nothing making contact anywhere. If there is no problems check all nuts and bolts are tightened to specifications. 17. Bleed the brakes in both front and rear. Drive the vehicle only enough to position the wheels straight ahead. 18. Now we will install the damper bracket and damper. There is different styles of damper brackets available, make sure you have the correct item, the pin-pin style is a universal type and this can be used on ute’s as well as wagons. Both types will be explained. Starting with your Steering damper fully compress the damper, put a small mark on the case to distinguish the full compressed size. Now fully open and mark again. Measure the distance and push the shock in half way .This is now the distance you require the damper to be when the steering is straight ahead.

fully closed measurement fully open measurement half way measurement images correct way to fit the taper pin style bracket, usually on wagons 1/2000 on below shows the

Images of proper Damper bracket alignment of pin-pin style.

Image’s above shows complete front suspension fitted

Now that you have the damper installed turn from full lock to full right and check there is nothing making contact that could cause damage, it is normal for slight contact of the damper shield to make contact with the drag link and panhard rod.

19.Fitment of the Tie rod ( behind the diff) is simply a matter of removing the original tie rod. To install the new tie rod providing the original Tie Rod was not bent if you do not move the tires during removal you can simply adjust the new tie rod out evenly to the same measurement as the knuckle holes and drop it into place. Tighten up both locking nuts and bolts as well as fitting the split pins.| NOTE: The tie rod fits opposite to the drag link with the clamp adjusting bolts facing backwards, the same as factory. 20. Check all bolts are properly tightened to specifications 21. Test drive, if you have any problems or questions call Superior Engineering. 22. Measure and record your bump stop Measurements The instructions are only a general guide and suspension work and fitting should only be performed by qualified mechanic with sound knowledge of the products they are fitting. Superior Engineering Takes no responsibility for any damage arising or caused by correctly or incorrectly fitted parts, if there is any doubt that a part was incorrectly supplied Superior Engineering Must be contacted and the parts Must not be fitted to the vehicle unless Written authority from Superior Engineering states you can fit the part in question.
