UMI Performance 64-72 GM A-Body Tubular Upper & Lower Front A-Arm Kit- Delrin Bushings

UMI Performance is known for making well-built suspension components that improve handling and performance, especially for classic muscle cars. This tubular upper and lower front A-arm kit for 1964-1972 GM A-Body vehicles is a prime example of their commitment to Pro Tour-ready upgrades. If you're looking to significantly improve your classic car's handling, especially if it's been lowered, this kit is designed to make a notable difference in steering feel and overall stability.

This kit features UMI-manufactured, greaseable, and fluted Delrin bushings in the lower arms, which are designed for zero deflection to ensure smooth suspension action. The upper ball joints are 0.9 inches taller than stock, which helps create a better camber curve, lowers the center of gravity, and reduces bump steer, similar to installing a taller spindle. The upper arms themselves use race-quality rod ends that are adjustable, meaning you can fine-tune alignment settings and reduce the need for shims. These arms are built using TIG-welded DOM tubing for strength and a clean look, with 4140 CrMo cross shafts that are CNC machined and zinc plated. They are designed to work with factory or drop spindles, and accommodate factory springs, lowering springs, and coilover kits. Polyurethane bump stops and spring isolators are also included, and the kit comes with recommended alignment specs and detailed installation instructions.

This kit is specifically intended for lowered vehicles, as the upper arm bump stop is not compatible with raised setups. It's a bolt-on installation that can transform the driving dynamics of your classic GM A-Body, making it more responsive and comfortable on the street or at the track. You'll find this kit fits a wide range of popular models like the Chevrolet Chevelle, Oldsmobile Cutlass, and Pontiac GTO.
