Eliminate unwanted traction problems by adding a UMI Performance tunnel brace mounted torque arm. This aftermarket torque arm replaces the flimsy factory torque arm while adding strength, rigidity and eliminating suspension flex. UMI’s torque arm design relocates the front torque arm mounting point off the transmission tail shaft protecting the transmission and preventing transmission damage. A shorter torque arm improves weight transfer on acceleration. General Motors tail shaft mounted design works great for a stock driven vehicle however it was not designed to take the abuse of a drag car. UMI’s tunnel mounted torque arm bolts to existing floor pan holes using 3/16” thick mild steel laser cut mounting plates and metric grade 10.9 hardware. The torque arm attaches to the supplied cross brace using polyurethane bushings on both the supplied cross brace and torque arm to help absorb noise. The torque arm rear mount is 3/8” thick CNC machined mounting plates and are appropriately drilled to fit the stock rear ends as well as aftermarket 12-Bolt’s, 9” Rear-end housings and Strange S60.
Torque Arm Benefits:
Rear torque arm hardware kit- We highly recommend purchasing a new hardware kit if running this torque arm on a factory rear-end, Strange or other similar rear-ends that use a straight through long bolt design. Factory torque arm bolts will work however are slightly too short and may not work correctly. For Moser Engineering 12-Bolt rear-end use P/N 2998, the Moser 12-Bolt uses four ½” bolts, P/N 2998 includes longer ½” bolts and spacers to reduce movement. P/N 2998 is for Moser 12-Bolt only, use P/N 3003 on Moser 9”.
