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

Starting with the 1.500" x 0.120" DOM tubing, these control arms from UMI Performance are built for strength and precision. This kit includes both tubular rear lower control arms and adjustable rear upper control arms, designed as a direct bolt-on upgrade for your 1968-1972 GM A-Body vehicle, including popular models like the Chevrolet Chevelle, Pontiac GTO, and Buick Skylark. Stock control arms can often suffer from bushing deflection and rust, leading to lost traction and unpredictable handling. This kit aims to correct those issues, offering a more consistent and responsive feel whether you're cruising or pushing your car on the track.

The lower control arms are well-built with grease-able Energy Suspension polyurethane bushings and feature TIG welded construction for maximum strength. UMI has also reinforced the sway bar mounting holes with a steel sleeve to prevent crushing under load. The adjustable upper control arms are where you gain significant tuning ability. Constructed with CNC machined steel mounting plates and 4140 chrome moly threaded adapters, these arms allow you to easily adjust your vehicle's pinion angle on the car, without removing the arm. This is crucial for optimizing performance, improving traction, and achieving precise handling characteristics. The solid adjuster is heat-treated for durability, and the entire assembly is finished with a durable gloss powder coat to resist corrosion and wear.

This kit is a comprehensive solution for improving the rear suspension geometry and performance of your A-Body. The combination of strong materials, precise construction, and on-car adjustability means you can fine-tune your suspension for a wide range of driving conditions. You'll find that wheel hop is significantly reduced, cornering is more predictable, and overall track consistency is improved.
