I just installed my 12 bolt (moser) with 4.10's and eaton posi, and found that on a god solid launch I get quite a bit of wheelhop. I am still using the stock suspension in the rear and really don' have the coin right now to upgrade. Could this have something t do with the way it is setup? could the pinion angle be causing this? I am pretty much in the dark when it comes to suspension tuning, I just know that it didn't wheelhop before and now it does... any help is appreciated.
Thanks,
Mike

 

If you are not running enough air in your slicks you will get violent wheelhop. I would try 15-17psi in the slicks and see what happens. If it still happens you have to look at the rest of your suspension.

I had the exact same thing.I just did a bunch of
suspension work and I am breaking in the new
clutch so I haven't really gotten on it.I would
suggest the poly trans mount and see what happens.
It's only like 25 bucks.

 

Actually this is on the street with Kumhos. Can't quite figure it out. the torque arm bolts are good and tight. everything ele is torqued to spec. I don't get it.
