1982 - 1992 GM F-Body Tunnel Mounted Torque Arm- Fits TH350 & T5 Transmissions


Application:
1982 - 1992 Chevrolet Camaro
1982 - 1992 Pontiac Firebird


This tunnel mounted torque arm is designed to work with a TH350 transmission installed into an 82-92 Camaro or Firebird. This item is supplied with a transmission crossmember with provisions to install a TH350 transmission and a new shorter style adjustable torque arm. The TH350 transmission does not have provisions to mount the factory torque arm onto the transmission tail shaft. This set-up makes the TH350 transmission swap an easy 100% bolt in installation. This item will also work with the factory T5 5-speed transmission. If you currently have a T5 transmission but have plans for a TH350 transmission swap in the near future we recommend this set-up.

This torque arm set-up is designed to remove the front mounting point of the torque arm off the transmission, protecting the tail shaft from damage. This torque arm is supplied with pivot brackets that allow (2) settings to allow easy instant center adjustments. By simply moving the torque arm into the next location you can automatically change the instant center point of the vehicle. This is very crucial on low to mid horse-power cars and can easily lower 60-foot times. This set-up bolts to existing floor pan holes using 0.188" thick mild steel CNC machined mounting plates and metric grade 10.9 hardware. The complete cross brace is constructed of 0.120" thick rectangular tubing and attaches to the torque arm using 0.250" thick mild steel mounting pivot plates with Grade 8 hardware. The torque arm is attached to the supplied cross brace using an Energy Suspension polyurethane bushing set-up on both the supplied cross brace and torque arm. Polyurethane was chosen as a mounting point to keep road noise at a minimum and eliminate unwanted "clunks" found with other set-ups available. The grease-able polyurethane bushings absorb road irregularities and protect noise from entering the passenger compartment. The rear mounting points feature 0.375" thick CNC machined mounting plates and are appropriately drilled to fit your stock rear as well as aftermarket 12-Bolt and 9" Rear-end housings. This set-up requires no welding or drilling and can be installed with basic hand tools; this is a complete bolt-in design!

Rear Torque Arm Hardware Kit- We highly recommend purchasing a new hardware kit if running this torque arm on a stock rear-end, Strange or other similar rear-ends that use a straight through bolt design. OEM torque arm bolts will work however are slightly too short and may not work correctly. If you are running a Moser Engineering 12-Bolt rear-end this kit is not needed, you must reuse hardware supplied by Moser Engineering. This kit however is recommended for the Moser 9".
