93-02 Fbody UMI Performance Adjustable Lower Front A-Arms – Street


Model Number: 2305
UMI Performance

UMI Performance tubular lower A-arms are built to offer a strong street-able set-up while reducing weight over the factory set-up. By adding UMI Performance lower A-arms it immediately removes 8lbs from the front of the vehicle while adding strength and increased performance. UMI tubular A-arms are designed to outperform the stock setup, whether it’s at the race track or an added improvement to a daily driver, they’ve been tested and improved to handle both applications. These lower a-arms can be installed on the stock K-member or any aftermarket K-member. They are designed to reduce front end weight, as well as “unsprung” weight, providing improved handling performance to the front of your vehicle. UMI Performance A-arms are built using strong DOM steel tubing, 3/16” thick CNC machined shock mounts, new ball joints installed, high quality chrome moly spherical Teflon lined rod ends and grease-able Energy Suspension polyurethane bushings.

UMI front lower A-arms are supplied with high quality spherical bearing rod ends which feature a Teflon lined self lubricating race. These rod ends replace the stock rubber bushings found in the rear of the OEM arms. This rod end design is to allow free movement and travel in the front suspension while adding additional front end adjustment when needed. The factory GM A-Arm features a rubber pivot bushing in this area; this is designed to rotate up and down as the suspension travels. Replacing this bushing with a solid bushing such as polyurethane would not allow the suspension to articulate correctly and would cause front suspension bind. The rod end we use features a Teflon lined self lubricating race designed for a quiet operation and will not allow suspension bind in this area.
