UMI Performance 78-96 GM B-Body Adjustable Upper Control Arms- Roto-Joint

If you're looking to dial in your suspension for better performance on the street or track, UMI Performance's adjustable rear upper control arms are a solid choice for your GM B-Body vehicle. These arms are designed to replace your stock units, offering a significant upgrade in handling and stability. They work by minimizing suspension deflection, which helps reduce unwanted wheel hop during acceleration and makes it easier to set your ideal pinion angle for improved power delivery.

What sets these apart is the Roto-Joint spherical bearing, which allows for more precise suspension movement compared to traditional rubber bushings. Plus, the on-car adjustability means you can make changes without having to remove the control arms, simplifying the tuning process. They're built tough with thick, CNC laser-cut mounting pads and a combination of TIG and MIG welding for strength, all finished with a durable powder coat. The chromoly adjuster and threaded adapters add even more robustness for long-lasting performance.

These control arms fit a wide range of GM B-Body cars from 1977 through 1996, including models like the Chevrolet Caprice, Buick LeSabre, and Pontiac Catalina. Installation is straightforward, typically taking 1-2 hours with basic hand tools, making it a manageable upgrade for many DIYers looking to improve their car's launch and cornering capabilities.
