1958-1964 GM Impala Biscayne Rear Lower Control Arms for Airbags Part Number: TBC-84B

Description

Global West Suspension produces rear lower control arms for the 1958, 1959, 1960, 1961, 1962, 1963, and 1964 Impala that support airbags.

One major improvement over stock is the ability to pivot at the frame without adding excessive loads on the frame mount. Global West uses a Teflon lined spherical bearing instead of rubber or polyurethane. The bearing allows the arm to pivot up and down and swing slightly side to side (because of the panhard rod) without putting additional stresses on the frame mount.

On the rear end side, the arm is built with a rubber bushing.

Why you might ask?

Rubber will provide some minor lateral movement that is required because of the panhard rod. In 1959 through 1964, 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.

The arm also has provisions for clamping the parking brake cable to the top of the arm just as the factory did.
