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

UMI Performance is known for making well-built suspension components that help you dial in your car's handling. These Ultimate adjustable upper control arms are designed for the rear of your GM B-Body vehicle, from models like the Chevrolet Caprice and Buick Roadmaster to the Pontiac Catalina. They are crucial for fine-tuning your suspension, especially if you're looking to improve track performance or simply want a more stable ride.

What makes these arms stand out is the combination of strong materials and smart design. UMI uses aircraft-quality 4140 Chrome Moly steel for the main body and adjuster, which is a tough material that can handle the stress of performance driving. The construction is TIG welded for solid joints. For smooth operation and to prevent noise, they've incorporated high-quality QA1 spherical rod ends with a Teflon lining. This setup allows for bind-free movement, which is a big help for reducing wheel hop and increasing traction, especially when you're lowering your vehicle or driving it hard at the track or autocross events. The real convenience comes with the on-car adjustability; you can easily change the pinion angle by simply loosening two jam nuts and turning the adjuster right on the vehicle, making tuning much simpler.

These control arms are a solid option for anyone looking to get more out of their GM B-Body's rear suspension. They are built to last and offer a significant improvement in adjustability and performance over stock components.
