UMI Performance 65-67 GM A-Body Adjustable Upper Control Arms- Poly Bushings

UMI Performance adjustable upper control arms allow you to adjust your vehicle's pinion angle for optimum performance, precise handling, and improved traction. They are constructed of CNC machined 0.250" steel mounting plates, 4140 chromoly threaded tube adapters, and a high-strength, 4140 chromoly, heat-treated 1.000" solid adjuster. The unique on-car adjuster allows for easy adjustments without removing or unbolting the control arm. These control arms feature grease-able Energy Suspension fluted polyurethane bushings, new Energy Suspension rear end housing bushings, and a durable gloss powder coat. They are designed to lower track 60-foot times, increase traction, and reduce unwanted wheel hop.
