Rear Adjustable Upper Control Arms
Rear Adjustable Upper arms make setting pinion angle easy. The control arm is designed with right and left-hand threads on the adjuster so the arm does not have to be removed in order to adjust length. Jam nuts secure the postistion after adjustment.
High misalignment spherical bearings are located on the frame side allowing the rear end to have proper movement. The rear end upper pivot mounts for street and handling applications should use rubber bushings. Note: If you use polyurethane bushings on the rear end upper mounts, the rear end will go into bind at the outer limits of travel. Rubber will allow for any additional movement.
