Global West's tubular lower arms are supplied with ball joints, bump stops, polyurethane control arm bushings, special sway bar end links, and a spring cushion for indexing the coil.
Why a rotating spring mount?
There are a three reasons why we built a rotating spring pocket.
First: A lot of people cut the coil spring to obtain a desired ride height. When you cut the spring, the spring will no longer line up in the lower arm or upper frame mount . In some cases this can cause the spring to make noise rubbing on the edge of the pocket. In this case the spring cushions solves the rubbing issue and by rotating it provides a way to re-index the spring.
Second: The spring will be indexed properly around the coil. If you will notice most tubular lower control arms have a flat plate that the spring sits on. There really is no index.
This places a lot of load at the very end of the coil spring rather than on the full coil. Over time this will fatigue the coil spring. Sag may occur. Third: Ride height adjustments can be made by shimming under the spring pocket.
