Product Description

The UMI Performance 302717-B rear control arms kit provides advanced suspension tuning capability for 1978-1988 Chevy G-Body vehicles. This double-adjustable setup replaces factory rear arms with high-strength tubular steel upper and lower arms using Teflon-lined spherical rod ends, allowing precise alignment control for toe, camber, pinion angle, and ride height. The black powder-coated finish enhances durability, and the rod-end bearings eliminate binding under load.

Designed in the USA with North American steel and precision fabrication techniques - including laser cutting and TIG welding - this kit is engineered for high-performance street, autocross, or drag strip use. Please note: mounting hardware is not included; bolt-in installation requires existing or separately sourced hardware. Ideal for enthusiasts upgrading rear suspension geometry on LS, SBC, Big Block or standard rear G-Body platforms.
