UMI Performance 2199-B Tunnel-Mount Torque Arm Suspension Crossmember Reinforcement

The UMI Performance 2199-B is a tunnel-mounted torque arm designed for high-performance and racing applications. Engineered for maximum strength and durability, this torque arm is built from 1.250" x 0.120" DOM seamless steel tubing and features TIG-welded 4140 chromoly steel tube adaptors for superior rigidity and fatigue resistance. An on-car adjuster constructed from heat-treated 4140 chromoly steel allows for precise pinion angle adjustments without removing the unit from the vehicle.

Key Features:

• Constructed of 1.250" x 0.120" DOM seamless steel tubing for exceptional strength-to-weight ratio
• TIG-welded 4140 chromoly steel tube adaptors for maximum weld integrity
• On-car adjuster built from heat-treated 4140 chromoly steel for easy pinion angle tuning
• All polyurethane bushings are greaseable to maximize bushing longevity
• Rear mounts feature solid ¾" rod eyes secured with Grade 8 hardware
• Rear mounting plates use 0.375" thick mild steel, compatible with stock, 12-bolt, and 9" rear-end housings
• Brilliant, durable powder coat finish for corrosion resistance and long-lasting appearance
• Tunnel-mounted design — requires use with UMI tunnel-mounted torque arm mounts

This torque arm is a direct upgrade for enthusiasts looking to improve rear suspension geometry, reduce wheel hop, and optimize launch performance. The greaseable polyurethane bushings offer a firm, responsive feel while still providing serviceability over time. Rear mounting plates are designed to fit stock housings as well as popular 12-bolt and Ford 9" rear-end swaps, making this a versatile solution for a wide range of builds.
