slow motion of launch

Thanks Allen, thats your tuning! Djm makes these pinion shims that go between the rear end and the bracket. Would these help?

I got the kit with a bucket that the rearend sets on,on top the leafs. Then there's another piece on top the housing that clamps it. I can adjust the front and back bolts to raise or lower pinion. Then reclamp the u bolts to hold it. Like Allen my transmission is raised about 2in. I also had to clearance some of the crossmembers under the truck for the larger driveshaft I run. Stock might not have problems.
