UMI Performance 2200CM-R Tunnel Mounted Torque Arm with Crossmember Reinforcement

The UMI Performance 2200CM-R is a high-performance tunnel-mounted torque arm designed to eliminate wheel hop, improve traction, and protect your transmission on GM F-body and similar rear-wheel-drive vehicles. This street/strip proven design relocates the torque arm from the transmission to the tunnel area, preventing cracked tail housings while optimizing instant center location and shortening launch response time.

Key Features:

• Fabricated from 1-1/4" USA DOM seamless steel tubing for maximum strength
• House-made 4130 chromoly tube adapters and adjuster for enhanced durability
• Heavy-duty USA rectangular tubing crossmember for superior reinforcement
• Bolt-on design requires no welding or drilling during installation
• On-car adjustable for pinion angle and instant center optimization
• Greaseable polyurethane bushings minimize road noise and vibration
• Includes double shear bracket for optional bolt-on driveshaft loop (UMI P/N 2204)
• Durable powder coat finish available in UMI red or gloss black
• 100% manufactured, tested, and raced in Philipsburg, PA USA

CrMo Upgrade: This chromoly version 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.

Rear Mount Compatibility: Features a robust 3/8" thick mild steel rear mount designed to fit stock axle housings as well as Moser 12-Bolt, Moser 9" with bracket, Strange S60, and Quick Performance 9" with bracket.

Important Installation Notes: Rear torque arm hardware kit (UMI P/N 3003) is required on most axles, as factory bolts may be too short. For Moser Engineering 12-Bolt applications, use P/N 2998 which includes longer hardware and spacers to prevent failure. Moser 9" applications use P/N 3003.
