Product Details
If you're looking to firm up the rear suspension on your 1978-1988 GM G-Body for improved handling and reduced wheel hop, this rear control arm kit from UMI Performance is a solid choice. This kit is designed to minimize suspension deflection, giving you a more responsive feel whether you're cruising the street, hitting the drag strip, or carving corners. It's a well-built addition that significantly upgrades your classic GM's rear suspension setup.
The kit features fully boxed lower control arms, constructed from 3" x 1-1/2" rectangular tubing with CNC machined radius ends. These arms are capped to keep debris out, maintaining a clean look while offering enhanced strength. The upper control arms are built for on-car adjustability, using heavy-duty CrMo adjusters and Teflon-lined rod ends. These rod ends allow for suspension articulation with minimal friction, which is beneficial for harder launches and overall smoother suspension movement. The upper arms also include sturdy 1/4" thick laser-cut mounting pads designed to fit various rear end housings, and the entire assembly is MIG welded for durability. All control arms come with greaseable polyurethane bushings and zinc-plated steel sleeves for longevity and performance.
This kit is designed to fit a wide range of GM G-Body vehicles from 1978 to 1988, including popular models like the Buick Regal, Chevrolet Monte Carlo, and Pontiac Grand Prix. The control arms are finished with a durable powder coat for long-lasting protection. Installation is straightforward, typically taking about 2 hours with basic hand tools, and the components are CNC machined for accuracy and consistency right here in the USA.
