Whiteline W63387 Control Arm Lower Inner Bushing Kit

The Whiteline W63387 is a rear control arm lower inner bushing kit engineered from Whiteline's proprietary synthetic elastomer material. Worn or failed control arm bushings are a leading cause of uneven tire wear, unbalanced braking, and unpredictable rear-end handling during cornering — this direct-replacement kit restores proper suspension geometry and driver confidence.

Unlike standard OEM rubber bushings, Whiteline's synthetic elastomer compound was developed after extensive materials testing to deliver superior geometry retention and shape memory without the harshness associated with solid polyurethane bushings. The result is a bushing that combines the load-bearing strength of a solid bushing with the compliance characteristics of rubber — a best-of-both-worlds solution for street and performance driving.
