Product Description:
This kit is for installing a Tremec 3550 or TKO transmission into a Third Generation F-Body. The kit includes the transmission crossmember required to install the Tremec transmission, along with their crossmember mounted adjustable torque arm. This kit makes the Tremec 3550/TKO swap an easy bolt right in installation!
If you want serious performance, handling, and traction when you're at the dragstrip, AutoX, or road racing; then you need a Spohn Performance fully adjustable torque arm, here's what it'll do:
Attaches to the rear axle and controls rear end torque during acceleration, transferring this energy into the tires, increasing straight line traction
Reduces nose-dive during braking
Eliminates wheel hop
Increases side bite during corner exit acceleration
Bolt-on system does not require complete interior removal as with other kits
No fabrication, welding or drilling required - 100% bolt-in installation!
Removes the torque arm pivot point from the rear of the transmission to the supplied crossmember
Changes the instantaneous center and leverage point from stock
Provides adjustable pinion angle
Poly version utilizes polyurethane front mount to keep noise at a minimum
Rod ended version utilizes a chromoly spherical rod end front mount for those who demand the best bind-free performance
Build Specifications:
Constructed of 1.25" o.d. x .120" wall DOM (drawn over mandrel) seamless mild steel tubing
TIG welded 4130 chromoly threaded tube adapters
Heavy-duty 3/8" thick steel rear housing mounting plates
Heavy-duty mild steel transmission crossmember with integral torque arm mounting system
Polyurethane bushing front mount for minimal road noise, Grade 8 hardware is supplied. Integral grease fitting allows for lubrication of the polyurethane bushing
Rod ended version utilizes a chromoly spherical rod end front mount for the ultimate in bind-free performance and strength. Grade 8 hardware is supplied
Unique rotating front torque arm mount, this system allows the torque arm to travel fore/aft which is VERY necessary with a torque arm suspension system. Solidly mounting the front of the torque arm causes the suspension to bind and hurts your car's handling drastically. The front rotator tube has an integral grease fitting to allow for proper lubrication.
Rear of torque arm mounts to the 3/8" thick steel rear housing mounting plates via two 3/4"-16 NFT x 5/8" bore x 7/8" thick solid steel rod ends. These are solid rod ends, not spherical bearing rod ends, so noise is of no concern. Grade 8 - 5/8" bolts and 5/8" nylock nuts are supplied.
Integral Pinion Angle Adjuster between the bottom rear solid rod end and the bottom rear torque arm tube allows for easy pinion angle adjustment. A simple turn of the wrench will give you 6 degrees of pinion angle adjustment, it's that simple.
Entire package is a complete bolt-in assembly using existing mounting points on the vehicle. No drilling or welding is required!
Available powder coated red or black.
