Relocate the Torque Arm Tunnel Mount in Your 1982-1992 F-Body for 4L60E Transmission Fitment with the UMI 2261-B
The UMI Performance 2261-B is a torque arm relocation kit for 1982-1992 GM F-Body Camaro and Pontiac Firebird applications swapping to or running a 4L60E automatic transmission. The factory third-gen F-Body tunnel mount for the torque arm is positioned for the 700R4 and T5 transmissions and is not dimensionally compatible with the longer 4L60E gearbox without modification.
The UMI 2261-B provides a fully welded, black powder coated steel crossmember and mount bracket that relocates the front torque arm mount to the correct position for 4L60E fitment, allowing the torque arm to run parallel to the driveshaft at the proper angle without interference. This kit is designed for use with UMI's tunnel-mount torque arm systems and is a mandatory companion piece for any 82-92 F-Body running the 4L60E swap. Manufactured in black powder coat at UMI Performance's facility in Philipsburg, Pennsylvania.

Frequently Asked Questions
What is the UMI Performance 2261-B?
The UMI 2261-B is a torque arm relocation kit for 1982-1992 GM F-Body Camaro and Pontiac Firebird builds using a 4L60E automatic transmission. It relocates the front torque arm tunnel mount to the correct position for 4L60E fitment, allowing a UMI tunnel-mount torque arm system to run at the proper angle and geometry with the longer 4L60E gearbox.
Why is the 2261-B needed for a 4L60E swap in an 82-92 F-Body?
The factory third-gen F-Body transmission tunnel mount was engineered for the 700R4 and T5 transmissions. The 4L60E is longer than these units, which moves the front torque arm mount position rearward relative to the factory tunnel location. Without relocating the mount, the torque arm cannot achieve the correct parallel geometry to the driveshaft, leading to bind, vibration, and premature wear. The UMI 2261-B provides the correct relocated mount position for proper 4L60E torque arm geometry.
Is the 2261-B compatible with all 82-92 Camaro and Firebird models?
The UMI 2261-B is designed for the 1982-1992 GM F-Body platform including all Chevrolet Camaro and Pontiac Firebird models of those years. It is intended for use with UMI's tunnel-mount torque arm systems combined with the 4L60E automatic transmission.
Does this kit work with the T56 or other manual transmissions?
The UMI 2261-B is specifically designed for the 4L60E automatic transmission swap on the 82-92 F-Body. If you are running a T56 or other manual transmission, contact UMI Performance directly to confirm compatibility and the correct relocation kit for your specific application.
What is the difference between the 2261-B and 2261-R?
The UMI 2261-B and 2261-R are identical in function, dimensions, and fitment. The only difference is the powder coat color: 2261-B is black and 2261-R is red. The choice between them is purely an aesthetic preference for the appearance under the car.
Is the 2261-B a bolt-in kit or does it require welding?
The UMI 2261-B is designed as a bolt-in installation. No welding or cutting of the chassis is required. UMI provides the necessary hardware for a straightforward under-car installation using standard hand tools.
Where are UMI Performance parts manufactured?
UMI Performance designs and manufactures its components in Philipsburg, Pennsylvania. All UMI chassis, suspension, and drivetrain hardware is produced domestically in the USA.
What torque arm do I need to use with the 2261-B?
The UMI 2261-B is designed to work with UMI's tunnel-mount torque arm systems for the 82-92 F-Body with 4L60E. Contact UMI Performance or refer to their compatibility guide to match the correct torque arm part number to your specific transmission and rear axle combination.
Installation Instructions
- Safely lift and support the vehicle on jack stands with adequate clearance to work under the car.
- Remove the driveshaft if required to access the tunnel area and existing torque arm front mount hardware.
- Identify and remove the factory torque arm front tunnel mount hardware from the transmission crossmember area.
- Position the UMI 2261-B relocation bracket in the tunnel, aligning the mount points with the factory holes or the provided mounting locations as specified in the UMI installation instructions.
- Install the provided hardware and snug all fasteners without final torquing until the torque arm is in place and alignment is confirmed.
- Install the torque arm into the relocated mount and align it parallel to the driveshaft.
- Torque all fasteners to 40 to 50 ft-lbs on the torque arm side and the bracket mounting hardware per UMI's specification.
- Reinstall the driveshaft and verify there is no interference between the torque arm, driveshaft, and any body or chassis components through the full range of suspension travel.
- Lower the vehicle and verify operation before driving.
