UMI Performance 82-02 F-Body On-car Adjustable Control Arms- Poly/Roto-Joint

If you're working on a 1982-2002 F-body like a Camaro or Firebird, these on-car adjustable lower control arms from UMI Performance are a solid choice for improving your suspension's performance. They replace your factory arms and use a combination of polyurethane bushings on one end and UMI's unique Roto-Joints on the other. This setup is designed to give you a bind-free suspension movement, which is crucial for getting better traction and reducing that annoying wheel hop, especially when you're putting down more power.

The Roto-Joints are the star of the show here. They allow for a generous 28 degrees of rotation, letting your suspension articulate freely without binding up. This is a big step up from stock rubber or even aftermarket polyurethane bushings because they prevent suspension bind, leading to improved handling and a more direct feel. The joint itself is built with a hard chrome-plated 4140 chromoly ball that rotates in a durable Delrin race, designed for serious wear resistance. Plus, they're adjustable on the car, so you can fine-tune your rear end's position to fit larger tires or center it properly, and they're completely rebuildable if the Delrin race ever needs attention.

On the chassis side, you've got polyurethane bushings. These are a bit softer and are designed to absorb more road noise and shock, keeping the ride comfortable for street use. Both the Roto-Joints and the polyurethane bushings are greaseable, making maintenance straightforward. These arms come fully assembled and ready to bolt on, using your vehicle's original hardware.
