UMI Performance 68-72 GM A-Body Adjustable Upper Control Arms- Poly Bushings

If you're looking to dial in the rear suspension on your 1968-1972 GM A-Body, these adjustable upper control arms from UMI Performance are a solid choice. They're built tough for street driving, strip use, or even some spirited corner carving. The key benefit here is the ability to easily adjust your pinion angle while the arms are still bolted to the car, which helps reduce suspension deflection for crisper handling and less wheel hop.

These arms are well-built with thick, CNC laser-cut mounting pads and a mix of TIG and MIG welding for strength. They feature greaseable polyurethane bushings with zinc-plated steel sleeves, which help minimize deflection and allow for easy maintenance. The CrMo threaded adapters add extra strength to the adjustment mechanism. UMI also applies a durable powder coat finish to protect against the elements. They're designed as a simple bolt-in replacement for your stock arms and work with all rear end housings.

Installation is straightforward, typically taking about 1-2 hours with basic hand tools. These arms are made in Philipsburg, PA, USA.
