Torque Arm ?

What is a Torque Arm and what does it do? When do you get to the point that you need one? Can someone please fill me in!?

Torque arms set the angle of the diffy to the driveshaft and hold the diffy to keep it from "winding up" with torque application. When the diffy "winds-up" and then pops back into place you get wheel hop on hard accel, usually at shifts. The banging is VERY hard on diffy gears - it breaks them in short order.

If you have banging from the rear end on hard accel, you may need a torque arm. There are other less expensive fixes, but they don't always work.

Doesn't one company make a TA that doesn't mount on the rear, therefor taking the stress off and putting it on the body?

I can't imagine any method to control differential torque without either gaining leverage from the body or from the ground. I guess you could put an arm on the back of the diffy to rollers that would hit the ground and stop the diffy from winding up, but it would slow the car some and look really awful. It would be the same as wheelie bars on dedicated drag racing cars.
