I had my gm dealer put in my new floor mounted spohn mild steel lt1 w/ long tube headers torque arm. However, whenever I launch the car, or raplidly accelerate or shift hard, I feel a clunk come from under the car. Almost as if the torque arm is shifting or shifting the floor or popping the metal. I drove it around for 15 minutes after I got it back from the shop and I took it back, they said to take it back tomorrow to get it checked out. Any ideas what could cause this?

I have the same T/A, it will clunk as the mount is movable. As the weight shifts, the mount pivots and the result is the noise. You can try tightening the swival point a bit but this can cause bind.(It's supposed to move)

Keep tightening a little at a time and try it. It will eventually quiet down quite a bit. There will still be times when you get clunks though. It's made to pivot at the front mount and that is what you are hearing.

ok thanks guys, I'm going to have the mechanic check the pinion angle and tighten it up some

Mine does it too. I have -1 degree pinion angle. I have heard that it pinion angle can increase the likeliness for it to clunk on acceleration or hard stopping, but I haven't checked myself. I'll be re-setting mine to 0 when I install springs and see if that helps a bit. Plus I do not need to preload the suspenssion for Road Course duty. But I've had mine in its current setting for over a year with several Road Course Track days and 1/4 mile passes and everything is holding together fine. Hope this helps.

Mine has never made a noise. they will move more than u think. I bet it is hitting the underside of the car under accel.
