UMI Performance 70-81 GM F-Body Upper A-arms Front Delrin Bushings

Starting with the 4140 CrMo offset cross shaft, these UMI Performance upper A-arms are built for strength and precise camber adjustment on your 1970-1981 GM F-Body. This allows you to dial in your alignment with fewer shims, which is a big help whether you're setting up for street cruising or track days. The arms themselves are constructed from strong, USA-made 1.250-inch DOM steel tubing, giving you a solid foundation for improved handling.

What really makes these arms stand out is the combination of UMI-built, greasable Delrin bushings and a high-quality ball joint that comes pre-installed. Delrin is known for its low friction and stiffness, which translates directly into a more responsive steering feel and less slop in the front end. You'll notice a reduction in wandering, especially at higher speeds, and a more connected sensation to the road. These are designed as a direct bolt-in replacement, making the installation process straightforward for a wide range of vehicles including Chevrolet Camaros, Pontiac Firebirds, and even some Buick and Oldsmobile models from the era.

This set is a significant upgrade for anyone looking to enhance their classic muscle car's handling characteristics. The added caster improves steering stability and self-centering, while the robust construction and precision bushings ensure durability and consistent performance. Consider adding the optional hardware kit for Grade 8 mounting hardware to complete the installation with new, strong fasteners.
