NEW! CST Performance Suspension 1999-2006 Chevrolet Silverado 1500 & GMC Sierra 1500 Upper Control Arm Kit # CSS-C2-16. CST has redesigned the now discontinued CSS-C2-1 arm kit and has replaced it with the CSS-C2-16. The primary upgrade to the older arm is the ball-joint construction has been improved and replaced with the CST Sealed Top Cap UniBall design. By sealing off the top of the UniBall CST is able to maximum UniBall life. Use of a UniBall instead of a ball-joint allows for the upper control arm to operate at steeper angles without binding. The older Ball-Joint design also limited suspension travel when running extended length front shocks. The updated design can provide up to 2" inches of additional suspension travel when paired with extended travel front shock absorbers. This Control Arm Kit includes machined taper pins designed only for use with the CST 4" Lift Spindles only. This Upper Control Arm will NOT fit stock steering uprights or the Fabtech 3" Lift Spindles.
