Description

Part #: 2237-R

The torque arm relocation kit from UMI is designed to remove the front mounting point of the torque arm off the transmission and protect the tail shaft from damage. General Motors tail shaft mounted design works great for a stock driven vehicle however it is not designed to take abuse and hard launches. This setup replaces your transmission cross member with a new stronger cross member with a built in torque arm mount. The relocation kit is designed to fit the heavy duty GM 4L80E transmission and will work with virtually any stock style aftermarket torque arm as well as the factory torque arm (Must use bushing #3004 to use a stock torque arm). This unit is built using USA steel tubing, 3/16" mild steel mounting plates and includes all necessary hardware needed for the installation. The torque arm mount is laser cut from 1/4" thick mild steel and features a new clam shell for appropriately attaching the torque arm to the new cross member. Please use the FAQ's below for additional information. Note: When running a factory torque arm you must purchase #3004 bushing below.

MIA's Description

The UMI Performance 4L80E Transmission Torque Arm Relocation Kit is specifically engineered to accommodate a heavy-duty GM 4L80E transmission in 1998-2002 GM F-Body vehicles (Chevrolet Camaro and Pontiac Firebird). This kit effectively removes the transmission's front mounting point for the torque arm and relocates the support, enhancing driveline strength and safeguarding the transmission tail shaft. It's an essential upgrade for builders seeking improved support without compromising ground clearance. Constructed from durable USA steel tubing and robust 3/16-inch mild steel mounting plates, the kit ensures dependable strength and long-term durability. The included crossmember is stronger than the stock unit and incorporates a built-in torque arm mount for a clean and purposeful design. The entire assembly is finished with a resilient red powder-coat for corrosion resistance and a bold aesthetic. Installation is rated as moderately easy, requiring no drilling, cutting, or welding. All necessary hardware is included, and the design is compatible with a solid 1-piece polyurethane bushing (a factory 2-piece style requires bushing #3004, sold separately). The torque arm mount is laser-cut from 1/4-inch thick mild steel and features a new clam shell for secure attachment of the torque arm to the new cross member.
