Rear torque arm hardware kit - UMI P/N 3003 is required on most axles. We highly recommend purchasing a new hardware kit as the factory torque arm bolts may be too short and may not capture enough threads. P/N 3003 fits factory, Strange and all others using a long straight through bolt design. For Moser Engineering 12-Bolt use P/N 2998. P/N 2998 includes longer hardware and spacers to reduce movement and prevents failure. Torque arms mounted to Moser 12-bolt and not using hardware kit P/N 2998 are not covered under warranty. Moser 9” uses P/N 3003.
