1958-1964 Impala, Biscayne, Bel Air, El Camino Rear Lower Tubular Control Arms sold as a pair # TBC-84

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 bushing. The bearing allows the arm to pivot, tilt,and swing slightly side to side (because of the panhard rod) without putting additional stresses on the frame mount.

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

Here is WHY!

Rubber will provide 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. Because we use rubber at this location the rear end can move in it's intended path without bind. If polyurethane was used, it would restrict the movement.

Another benefit is a rotating spring cushion for indexing the coil spring. The spring cushion can be rotated during assembly for proper index. So if you trimmed the spring for lowering you can still get a good index between the upper and lower spring mounts.

They also have provisions for clamping the parking brake cable to them just as the factory did.
