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.
• No fabrication, welding or drilling required – 100% bolt-in installation with the use of basic hand tools!
• 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.

Build Specifications & Features:

• Constructed of 1.25″ o.d. x .120″ wall DOM tubing.
• TIG welded 4130N chrome moly threaded tube adapters for maximum thread strength.
• Heavy-duty CNC laser cut 3/8″ steel rear axle housing mounting bracket.
• Heavy-duty dual 1.25″ x .120″ wall DOM tubular crossmember with integral torque arm rotator mounting system. Our rotating front torque arm mount (thrustator) 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.
• Del-Sphere™ pivot jointed front mount provides for bind-free articulation and the best in street-friendly performance and strength.
• Rear of torque arm mounts to the 3/8″ steel rear axle housing mounting bracket 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 4140 chrome moly pinion angle double 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.
• 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.
• Available powder coated in your choice of bright red or gloss black for a brilliant and durable finish.
• Includes a front 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 driveshaft failure.
