REMEMBER!When installing new camshaft please remember that the contact surface of the follower must be free of wear/smooth surface.ADJUSTABLE SPROCKETSCrower's new cam sprockets are made from premium 6061-T6 billet aluminum and incorporate a four bolt ARP® fastening system to prevent the slippage found in other brands. The lightweight design (327g) reduces unwanted harmonics which could cause valve train failure. To have the full potential of your cam performance, cam sprockets are required.
Duration fi gures are taken at the valve. Gross lift calculated by using the following rocker ratios: Mid (VTEC) - 1.55, Secondary - 1.50, Primary - 1.45.

Duration figures are taken at the valve.Gross lift calculated by using the
following rocker ratios: Mid Lobe (VTEC) - 1.55, Secondary Lobe - 1.50, Primary Lobe - 1.45.
Note: When ordering valves, be sure to specify one set int and one set exh. Note: When ordering sprockets, be sure to specify two.
STAINLESS STEEL VALVESMade from the highest grade stainless steel, this new Crower valve is a must for high horsepower, high boost and high rpm applications. The exclusive “Pro Flo” head design delivers a significant increase in cylinder head flow figures, while the tip area is hardened to RC50, including past the critical keeper groove area for added strength. Fully CNC machined and swirl polished to insure that you will get the best performance valve available on the market. Choose from standard, 1⁄2 mm, 1 mm and 2 mm oversize. Titanium valves also available. Contact Crower for availability. When ordering sprockets, be sure to specify two.
Note: Valve guides may require honing to size. All Crower VTEC valves are 5.5mm stem diameter. Factory guides may vary depending on specific engine.

Note: Specify “Z” after part number if D16Z6 (92-95) or “Y” after part number if D16Y8 (96-up). All duration figures listed above are specific to the D16Y8.Gross lift calculated by using the following rocker ratios: Int Mid Lobe (VTEC) - 1.60, Int Sec Lobe - 1.60, Int Pri Lobe - 1.60, Exhaust - 1.80.
ADJUSTABLE SPROCKETSCrower's new cam sprockets are made from premium 6061-T6 billet aluminum andincorporate a four bolt ARP® fastening system to prevent the slippage found in other brands. For the ultimate tuner, Crower sprockets feature 5/16" diameter, 12 point ARP®fasteners with a hardened washer to prevent galling and stripping. The lightweight design (367g) reduces unwanted harmonics which could cause valve train failure.
Note: When ordering sprockets, Y = D16Y8 (96-up), Z = D16Z6 (92-95).Note: When ordering valves, be sure to specify one set int and one set exh.
