UMI Performance 2200-B Tunnel Mount Torque Arm with Crossmember Brace

The UMI Performance 2200-B is a tunnel-mounted torque arm system designed to eliminate wheel hop, improve traction, and reduce 60-foot times on GM rear-wheel-drive vehicles. This bolt-on performance upgrade replaces the factory torque arm with a shorter, more rigid design that optimizes instant center geometry and shortens response time for improved launches.

Key Features:

• Fabricated from 1-1/4" USA DOM seamless steel tubing for maximum strength
• House-made 4140 chromoly tube adapters and adjuster for durability
• Heavy-duty USA rectangular tubing crossmember for rigid tunnel mounting
• Greaseable polyurethane bushings minimize road noise while maintaining performance
• Adjustable design allows on-car pinion angle and instant center adjustments
• Bolt-on installation requires no welding or drilling
• Includes double-shear bracket for optional bolt-on drive shaft loop (UMI P/N 2204)
• 3/8" thick mild steel rear mount fits stock axle housings, Moser 12-Bolt, Moser 9" with bracket, Strange S60, and Quick Performance 9" with bracket
• Available in durable UMI red or gloss black powder coat finish
• 100% manufactured, tested, and raced in Philipsburg, PA USA

CrMo Upgrade Option: The chromoly version (suffix -B) uses USA 4130 CrMo tubing with 100% TIG welding for increased strength and reduced weight. Recommended for vehicles running 10.50s and faster in the quarter mile.

Important Notes: Rear torque arm hardware kit UMI P/N 3003 is required for most axles, as factory bolts may be too short. Moser 12-Bolt applications require P/N 2998 with longer hardware and spacers. By mounting to the tunnel instead of the transmission, this design eliminates the risk of cracked tail housings common with factory torque arms.
