UMI Performance 220170-R Tunnel Mount Torque Arm & Subframe Connector Kit

The UMI Performance 220170-R is a complete tunnel-mounted torque arm and subframe connector system engineered to deliver maximum traction and chassis rigidity for 1993-2002 GM F-Body vehicles. This bolt-on drag race solution combines the proven 2201 tunnel-mounted torque arm with reinforced 3-point subframe connectors to dramatically reduce chassis flex and improve launch performance.

Key Features:

• Shortened tunnel-mounted torque arm improves instant center location for enhanced forward traction
• 3-point subframe connectors reinforce chassis and prevent quarter panel buckling during hard launches
• Includes removable and replaceable NHRA-approved driveshaft loop for competition compliance
• Complete kit braces entire underside of car to minimize chassis flex under power
• Proven to reduce 60-foot times with improved weight transfer characteristics
• All necessary mounting hardware included for bolt-on installation
• Race-proven design, 100% manufactured in the USA

This comprehensive suspension reinforcement system works synergistically to stiffen the chassis structure while optimizing drivetrain geometry for maximum acceleration. The tunnel-mounted torque arm relocates the mounting point higher in the chassis compared to stock axle-mounted designs, creating a more favorable instant center that plants the rear tires harder on launch. Combined with the reinforced subframe connectors, this kit transforms chassis dynamics for serious drag racing applications.

Note: UMI 3003 bolt kit recommended for optimal installation.
