Model Number: 315
Spohn Performance

This kit is for installing a T-56 transmission from a 1993-1997 F-Body into a Third Generation F-Body. The kit includes the transmission crossmember required to install the T-56 transmission, along with our crossmember mounted adjustable torque arm. Our kit makes the T-56 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 wheelhop
  • Increases sidebite 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 QA1 extra high strength, chrome moly spherical rod end with Teflon?/Kevlar? self lubricating race for those who demand the best in bind-free performance and strength
  • FREE angle finder included to set pinion angle

Build Specifications:

  • Constructed of 1.25″ o.d. x .120″ wall DOM mild steel tubing
  • TIG welded 4130 chrome moly threaded tube adapters
  • Heavy-duty 3/8″ thick laser cut steel rear housing mounting bracket
  • 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 fluted polyurethane bushing
  • Rod ended version utilizes a QA1 extra high strength, chrome moly spherical rod end with Teflon?/Kevlar? self lubricating race for those who demand the best 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.
  • 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 over 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!
  • NHRA rules require a driveshaft safety loop on any vehicle running quicker than 13.99, or on any car running slicks. NHRA rules call for a loop with at least .250″ wall thickness, located no more than 6″ from the front u-joint. All Spohn Performance driveshaft safety loops meet every NHRA specification requirement in both build construction, and mounting location.
  • Available powder coated bright red or gloss black.
  • This is a proven product being run on some of the fastest F-Bodies in the country!
  • Rear mounting bracket is designed to fit on the OEM rear or an aftermarket 12 bolt or Ford 9″ rear

By request of our customers, we now offer the option of getting your torque arm with a front and rear driveshaft safety loop. NHRA rules call for a front driveshaft safety loop to prevent catapulting of the vehicle in the event of a front u-joint or shaft failure. While a rear u-joint or shaft failure will not catapult the vehicle, it will take out anything in it’s way, ie. rears, suspension components, brake lines, floor boards, etc. Protect yourself, and your investments, and play it safe by containing the front and the rear of the driveline.

NOTE: Do not get a rear driveshaft safety loop if your car is lowered.

Now Available: The ultimate in bullet-proof lightweight strength, 100% TIG welded chrome moly construction! Same as above, but torque arm is constructed entirely from 1.25″ x .095″ 4130 chrome moly tubing. Make your choice below.
