UMI Performance 64-72 GM A-Body Rear Lower Control Arms Boxed

UMI Performance is known for making well-built suspension components for classic American cars. If you're working on a 1964-1972 GM A-Body vehicle, like a Chevrolet Chevelle, Buick Skylark, or Pontiac GTO, and want to tighten up the rear suspension, these boxed rear lower control arms are a solid choice. They help reduce unwanted movement in the suspension, which means less wheel hop when you accelerate hard and more predictable handling when you're cornering.

These control arms are constructed from 2” x 1-1/2” x 1/8” wall mild steel tubing and are CNC machined for accuracy. They’re MIG welded with heavy-duty bushing holders and come assembled with greaseable polyurethane bushings. The sway bar mounting holes are also reinforced with TIG welded sleeves, so you can still mount a factory-style sway bar, including UMI's own 1-inch version. The durable powder coat finish helps protect them from the elements.

Installation is straightforward and can typically be done in about an hour with basic hand tools. These arms are designed to minimize suspension deflection, giving you a more responsive feel from your rear suspension.
