UMI Performance 78-88 G-Body Boxed Lower Control Arms- w/ Dual Roto-Joints

If you're working on a 1978-1988 G-Body like a Buick Regal, Chevy Monte Carlo, or Pontiac Grand Prix, these boxed lower control arms from UMI Performance are a solid upgrade. They replace your stock arms with a much stronger, bind-free design that uses UMI's Roto-Joint technology. This setup is built to handle more power and improve how your rear suspension moves, especially when you're pushing the car hard.

These control arms are fabricated from 3-inch by 1-1/2-inch, 0.120-inch wall rectangular steel tubing, giving them a strong, well-built structure. The Roto-Joints on each end feature a greaseable Delrin race that allows for a full 28 degrees of unrestricted movement. This means your rear end can articulate freely without binding, which is crucial for better traction and reducing wheel hop, whether you're on the street or the track. The arms also include reinforced provisions for a rear sway bar, making installation straightforward if you plan to add one.

With MIG and TIG welding throughout and CNC machined bushing holders, these control arms are made for accuracy and durability. They come fully assembled and ready to bolt on, finished with a tough powder coat. This set is designed to provide a noticeable improvement in handling and stability for your G-Body.
