Rear Control Arms
The Global West Advantage: One major improvement over stock is the ability to pivot at the frame without adding excessive loads on the frame mount. The X frames are noted for not being strong. Global West uses a PTFE 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. So consequently rubber is the best choice for our application. 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.
The arms are powder coated black and are fully assembled. They also have provisions for clamping the parking brake cable to them just as the factory did.
