1965-1970 GM B-Body Rear Lower Control Arm w/ Spherical Bearing and Rubber Bushing Part Number: TBC-50

Description

 

 

One major improvement over stock is the ability of the lower control arms to pivot at the frame without adding excessive loads to the frame mount. Global West uses a Teflon lined spherical bearing instead of rubber or polyurethane bushing. The bearing allows the arm to pivot and tilt without bind. The bearing also allow the rear suspension to arc do to the panhard rod. The panhard rod technically pushes and pulls the differential side to side as the suspension moves up and done. If a spherical bearing was not used in the lower control arm at the frame mount, restriction to movement will occur.

On the rear end side we use a rubber bushing.

Why you might ask?

Rubber allows lateral movement that is required because of the panhard rod. The factory used a panhard rod to control the rear end side to side movement. Unfortunately, the panhard rod is fairly short. As the rear end moves up and down, it also moves slightly left and right because of the arc of the panhard rod. Therefore, rubber is the best choice for our application. If polyurethane was used, it would restrict the movement.
