Product Details
UMI Performance is known for making well-built suspension components, and these adjustable rear upper control arms are a prime example. If you're working on a 1964-1967 A-body car like a Chevelle, GTO, or Skylark, these arms are designed to improve your car's handling and adjustability.
The key feature here is UMI's Roto-Joint spherical bearing. It significantly reduces suspension deflection, which translates to a more responsive feel when you're cornering and helps minimize wheel hop when you launch. These arms are also adjustable while still bolted to the car, making it easier to fine-tune your pinion angle. They're built with 1/4-inch thick CNC laser-cut mounting pads and a combination of TIG and MIG welding for strength, plus a durable powder coat finish.
These control arms are a direct bolt-in replacement and are designed to fit a wide range of rear end housings. Installation is straightforward and typically takes 1-2 hours with basic hand tools.
