Spohn Performance® - Adjustable Standard Duty Torque Arm

If you need bullet-proof strength, serious performance, improved handling, and pavement digging traction when you're at the dragstrip, AutoX, or road racing; then you need a Spohn Performance 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 

NO FABRICATION, WELDING OR DRILLING REQUIRED - 100% BOLT-IN INSTALLATION!

Removes the torque arm pivot point from the transmission tail shaft to the supplied transmission crossmember

Changes the instantaneous center and leverage point from stock

Provides adjustable pinion angle

Build Specifications:

TIG welded 4130N chrome moly threaded tube adapters

Extreme-duty CNC laser cut 3/8" steel rear housing mounting bracket

Heavy-duty fabricated steel transmission crossmember with integral torque arm mounting system

Polyurethane bushing front mount version for minimal road noise. Integral grease fitting allows for lubrication of the polyurethane bushing

Rod ended front mount version utilizes an extra high strength chrome moly spherical rod end with Teflon self lubricating race for those who demand no bushing deflection and the best in BIND-FREE performance and STRENGTH

DEL-SPHERE front mount version utilizes an extra high strength chrome moly Del-Sphere pivot joint for those who demand no bushing deflection and the best in STREET-FRIENDLY BIND-FREE performance and STRENGTH

Rear of torque arm mounts to the 3/8" steel rear housing mounting bracket via two 3/4"-16 NFT x 5/8" bore x 7/8" thick solid rod ends. All Grade 8 hardware is supplied.

Integral 4140 chrome moly pinion angle adjuster between the bottom rear 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.

Unique rotating front torque arm mount (THRUSTATOR), 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.

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 stock and/or aftermarket rear ends

WE OFFER THE OPTION OF GETTING YOUR TORQUE ARM WITH FRONT AND REAR DRIVESHAFT SAFETY LOOPS: NHRA rules call for a front driveshaft safety loop to prevent catapulting of the vehicle in the event of a front u-joint or driveshaft 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 investment, and play it safe by containing the front and rear of the driveline.
