These heavy duty rear control arms are much stronger than stock stamped arms and help control wheel hop. Trailing arm bushings are not included but are available. Can be used with Speedway polyurethane bushings # 916-34045 or stock-style bushings such as Moog K-6178.
Note: The lower control arms in these kits do not have provisions for mounting a factory sway bar.
NotesBushing installation note: The bushing eyelets have a stepped inside diameter. This requires the bushings to be installed into one specific side of the arm which has the larger inside diameter as compared to it's opposite side. The bushing will not properly fit if it is started into the smaller, incorrect side of the bushing eye ring.
- Upper Arms: 11-1/4"
- Lower Arms: 19-1/2"
(Measurements are center to center of the bushings.)
