UMI Performance 68-72 GM A-Body Lower Control Arm & Adjustable Upper Control Arm Kit - 401525-B

This kit from UMI Performance includes tubular rear lower control arms and adjustable rear upper control arms. It is a direct bolt-on replacement designed to reduce wheel hop, enhance cornering, and improve track consistency for your A-Body vehicle. Stock control arms are often subpar, leading to bushing deflection, rusting, and weak materials that result in traction loss and poor handling. Whether you are a weekend cruiser or a track enthusiast, this kit is suitable for all applications. The lower control arms feature grease-able bushings, TIG welded construction for maximum strength, and provisions for adding a stock or aftermarket sway bar. The sway bar holes are reinforced with a 0.120" wall thickness steel sleeve to prevent crushing. The adjustable upper control arms allow you to optimize your vehicle's pinion angle for better performance, precise handling, and improved traction. These upper control arms are constructed with CNC machined 0.250" steel mounting plates, 4140 chrome moly threaded tube adapters, and a high-strength, heat-treated solid adjuster. UMI Performance's unique on-car adjuster makes adjustments easy without the need to remove the control arm from the vehicle. The control arms also feature grease-able polyurethane bushings and a durable gloss powder coat for longevity. Overall, these control arms are built using 1.500" x 0.120" DOM tubing, CNC machined for precision, and feature MIG and TIG weld construction for superior strength. They are designed to provide lasting performance and durability for your vehicle.
