I just threw in a 3.5" LPE driveshaft, and I'm actually happy with the seat-of-the-pants improvement. Can't feel any power improvement, but it's the solid feeling between shifts I get. Anyway, I've tried a couple hard 1-2 shifts with it, and now I've got wheel hop. This is shaking hard enough that I'm kinda leary about putting the DR's on and running it down the track because I'm afraid of breakage.

I never had wheel hop before I put this shaft in. Maybe time to dust off the Spohn LCA brackets that have been on my shelf for 3 years now and get them installed?

 

A driveshaft won't cause wheel hop. Verify your torque arm is properly seated in the front mount. You can swap the old driveshaft back in and see if the problem still presists.

 

The problem never started until I put this shaft in. And the torque arm never came out to put that shaft in either.
