UMI Performance 4027 - 1964-1972 GM A-Body Double Adjustable Lower Control Arms

Our double adjustable lower control arms are designed for peak performance and durability. Featuring TIG welded fabrication, reinforced sway bar holes, and QA1 Endura Series Teflon-lined spherical rod ends, these arms ensure bind-free operation and eliminate rear-end bind common with rubber and polyurethane bushings. Ideal for drag racing, they withstand high torque and horsepower.

Constructed from 0.120" x 1.500" mild steel DOM tubing with 4140 Chrome Moly threaded tube adapters, these arms offer superior strength and thread durability. Reinforced sway bar holes with a 0.120" wall thickness steel sleeve ensure stability, while CNC machined aluminum step bushings with steel sleeves keep the control arm centered.

Measuring 22 inches center to center, they come with QA1 3/4" Hard Chrome Plated, Teflon/Kevlar Self Lubricating Race Rod Ends and a durable powder coat finish. Designed for quick on-car adjustability using right and left-hand threads, installation is straightforward and takes just one hour using OEM hardware.
