UMI Performance 68-72 GM A-Body Rear Control Arm Kit Fully Boxed Lowers

Starting with the 3" x 1-1/2" rectangular steel tubing, these UMI Performance boxed lower control arms are built to handle the demands of your classic GM A-Body. The fully boxed design, with capped radius ends, not only looks like the factory piece but also keeps debris out, maintaining that clean, original appearance. This attention to detail means you get enhanced performance without sacrificing the classic aesthetic of your 1968-1972 Buick, Chevrolet, GMC, Oldsmobile, or Pontiac.

These control arms are assembled with greaseable polyurethane bushings and zinc-plated sleeves, offering a comfortable ride while minimizing suspension deflection. This is crucial for reducing wheel hop, especially if you're putting down more power or enjoying spirited driving. The sway bar mounting holes are reinforced with TIG-welded sleeves, ready to accept factory-style sway bars, including UMI's popular 1-inch version. Whether you're building a street cruiser, a strip car, or a corner-carving machine, these arms provide a solid foundation for a crisp handling setup.

Installation is straightforward, typically taking about an hour with basic hand tools, and the durable black powder coat finish ensures they look great for years to come. Made in Philipsburg, PA, USA, these control arms are a well-built upgrade for your classic GM.
