Product Description:
This adjustable torque arm package includes the transmission crossmember for the installation of a LS1 (F-Body) based T56 transmission in to a 1982-1992 F-Body, along with Spohn's crossmember mounted adjustable torque arm. For proper alignment, this kit should be used in conjunction with LSX swap motor mounts.
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 QA1 extra high strength, chromoly spherical rod end with Teflon®/Kevlar® self lubricating race for those who demand the best in bind-free performance and strength
Build Specifications:
Constructed of 1.25" o.d. x .120" wall DOM mild steel tubing
TIG welded 4130 chromoly 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, chromoly 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
Spohn now offers 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 chromoly construction! Same as above, but torque arm is constructed entirely from 1.25" x .095" 4130 chromoly tubing.
