UMI Performance 1978-1988 GM G-Body Rear Tubular Upper & Lower Control Arms Kit - 301516-R

Fits 1978-1988 Buick Regal, Chevrolet Malibu, Chevrolet Monte Carlo, Oldsmobile Cutlass, Pontiac Grand Prix, and Pontiac LeMans.

UMI Performance tubular rear control arms provide a significant suspension upgrade for GM G-Body vehicles, addressing the inherent weaknesses of factory stamped-steel arms. By replacing flexible OEM components with rigid tubular steel, this kit minimizes wheel hop, improves cornering stability, and increases traction for both street and track applications. The included greaseable polyurethane bushings offer a performance-oriented alternative to soft rubber, reducing deflection while maintaining a comfortable ride quality.

These control arms are a direct bolt-on replacement for factory hardware. The lower control arms feature integrated sway bar mounting holes compatible with stock and most aftermarket sway bars. Every kit is CNC machined for precise tolerances and features fully TIG and MIG welded construction for maximum durability.
