This particular lower arm will fit 1968, 1969, 1970, 1971, 1972, 1973, and 1974 Nova, Ventura, and Apollo models applications and also 1968, 1969 Camaro and Firebird applications. The standard spring pocket is upgraded in the arm for a special poly cushion that indexes the spring whether you have trimmed it or not. Simply index the spring in the frame first and then rotate the cushion so the end of the spring indexes in the control arm.
Three advantages when choosing a rotating spring pocket:
1. Many 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. Global West designed spring cushions to solve the rubbing issue. Rotating the cushion provides a way to re-index the spring.
2. The spring will be indexed properly around the coil. You will notice that 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 and sagging may occur.
3. Ride height adjustments can be made by shimming under the spring pocket.
