A note from Interstate Trailers to our valued dealers and customers.

The scope of this manual is to provide parts and service information for year model 1998 and newer DT/DTA series trailers. We have made our best effort to document the common replacement parts for these trailers. However, Interstate Trailers Inc. builds many custom trailers which may be equipped with parts and options not listed in this manual. Also, trailers older than model year 1998 have some differences and will require help from the factory staff to locate the correct parts. If you encounter such a situation please call our factory at 1-800-433-5384 between the hours of 8 a.m. to 5 p.m. standard time, M-F excluding holidays. Interstate Trailers recommends that you always have your VIN number (trailer serial) ready when calling a dealer or the factory to assist in locating the correct parts for your trailer. Interstate Trailers will make every effort to help find the correct replacement parts for your trailer and will strive to make your ownership experience as trouble free as possible. *In April of 2000 Dexter Axle made a design change to the electric brakes used on all trailers with electric brakes listed in this catalog. This manual covers only the new style (post 04/2000) brakes. The difference is the construction of the backing plate, pre 04/2000 the backing plate was a stamped sheet metal plate and post 04/2000 the backing plate changed to a sand cast steel plate. The brake components differ between the types so please check your trailer prior to ordering parts to insure accuracy.
