I am not satisfied with it. Possibly after I spend more money.

I can't remember if you have the DTS or factory rear end? What seems to be the problem?

 

[FATJACK]

DTS style, good axles, Detroit locker. Had a local shop cut off the end caps on the diff. and replace with the 4 bolt style ends. Still having problems with wheel hop, think it has something to do with pinion angle.

 

[SrtBrad]

What is your pinOn angle?

 

[Slitherbeast]

I think you need a 4-link! truck is to heavy for a BIG launch! The 4-link will be more stable. just a thought.....

 

[FATJACK]

What is your pinOn angle?

0 degrees, I understand it needs to be 5 to 7 degrees negative.

 

[VENOMOUS1 RACING]

0 degrees, I understand it needs to be 5 to 7 degrees negative.

0 is good but I like about 3 degrees negative. 5-7 will give you harmonic vibrations that'll vibrate into the cab.
Wheel hop is likely in worn shocks or incorrect shock settings. Still have the kicker shock on dts axle?

Jack, I'm genuinely surprised you would let something small like that hold you up.
