This torque arm is for a 1982-1992 GM F-Body that already has one of our transmission crossmembers with a torque arm mount. Pro-Series torque arm comes complete with everything needed minus the transmission crossmember. Spohn Pro-Series torque arms are the strongest and hardest hooking torque arms on the market. If you have a standard Spohn torque arm and want to upgrade to the Pro-Series torque arm then this kit is what you need.
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 wheelhop
- Increases sidebite during corner exit acceleration
- Entire package is a complete bolt-in assembly using existing mounting points on the vehicle. No drilling or welding is required!
