1965-1968 GM B-Body Rear Upper Adjustable Tubular Control Arms with Spherical Bearing and Rubber Bushing Part Number: TBC-51

Description

 

 

Global West Suspension sells adjustable rear upper tubular control arms for the Impala, Biscayne, Caprice, Bel Air (model years–1965, 1966, 1967, and 1968).

Our rear adjustable control arm makes 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 the length. Jam nuts secure the position after adjustment. An adjustable upper arm is required if you are installing a nine inch Ford rear end.

A high-misalignment spherical bearing is located on the frame side allowing the rear end to have proper movement. The rear end upper mount for street and handling applications should use rubber bushings. This is because of the lateral movement caused by the panhard rod.

Note: If you use polyurethane bushings or our Del-a-lum bushings, the rear end will go into bind at the outer limits of travel. Rubber will allow for any additional movement required.

The arm is sold individually — some rear ends have two upper trailing arms. If this applies to your car, you will need to order two kits.

Note: Some 1969 frames have been found on 1968 models. The upper arm length is substantially different between the two frames. The 1969 upper arm is shorter — 9 5/8 inches long. The 68 arm is 12 5/8 inches long.
