Upgrade to UMI's fabricated tubular a-arms and improve your vehicles street and track performance.

The lower a-arms feature tough tubular construction and greaseable Delrin bushings for precise handling and smooth suspension motion. We build the Delrin bushings in-house to ensure the ultimate in quality and smooth suspension action.
