Description
Global West’s coilover tubular lower arms allow QA-1, Afco, and Air Ride technology components to bolt directly on. We took a good look at the stock lower arm and the installation of a coilover kit in place of the standard spring. Which by the way installs on the top of the control arm, not from underneath. We felt we needed a control arm specifically designed to handle the load of a coilover application. The design of the lower arm would also clean up the appearance showing off the coilover kit.
The arm offers 4 major strength areas to look at:
1. Doubling plates are used in the loaded areas where the shock bolts to the arm.
2. Cross tubes support the loaded shock mounting area and outside main tubes.
3. The sway bar mounting plate adds support to the ball joint area.
4. Straps are used around the bushing housings strengthening the housing to the tube.
CTA-88H will not except standard coil springs.
The arms are supplied with ball joints, bump stops, and control arm bushings. They are designed to handle the increased load being placed through the shock attachment points versus the conventional stock spring location.
