UPR Products 78-88 G-body/65-72 A-Body Extreme Spherical Bushings

UPR Products 1978-1988 G-Body / 1965-1972 A-Body Extreme Spherical Bushing Kit

Upgrade your GM G-Body or A-Body rear suspension with the UPR Products Extreme Spherical Bushing Kit. Precision CNC machined from ultra-strong 7075 billet aluminum and equipped with premium Teflon-lined COM bearings, these spherical bushings eliminate the deflection of factory rubber bushings to improve suspension articulation, rear axle movement, and traction. Designed for serious street, drag racing, and high-horsepower applications, this kit delivers smoother suspension operation and more consistent launches.

The bushings are designed to press directly into the factory rear housing while replacing the original rubber bushings. The Extreme Series package includes upgraded stainless steel sleeves and larger 1/2-inch Grade 8 hardware for maximum durability in demanding applications. Finished with a brushed machined appearance and manufactured from aircraft-grade 7075 billet aluminum, this kit is built to withstand years of abuse on the street or track.
