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!
This tunnel-mounted torque arm is specifically designed for use with a TH400 (Short tail Only) transmission in an 82-92 Camaro or Firebird. The kit includes a transmission crossmember with provisions for the TH400 and a new adjustable torque arm. This setup allows for a straightforward bolt-in installation of the TH400 transmission. The torque arm setup removes the front mounting point of the torque arm from the transmission, protecting the tail shaft from damage. It also includes pivot brackets that allow for easy instant center adjustments, crucial for improving performance on low to mid horsepower cars. The set-up is constructed using high-quality materials, including CNC-machined mounting plates and Grade 8 hardware for durability. For those running the torque arm on stock rear-ends or similar designs, a Rear Torque Arm Hardware Kit is recommended for optimal performance. If using a Moser Engineering 12-Bolt rear-end, hardware supplied by Moser Engineering should be used. A separate kit is recommended for the Moser 9" rear-end.
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".
