Here is a thread that discusses LCAs and the UCA and pinion angle

Ok I will check that out, thanks

 

damn, you're really, really low. forget the adjustable lower ca's and get an adjustable upper ca. you say it's only a vibration at wot and not at certain speeds? that tells me it's something other than pinion angle/driveline. maybe something contacting at wot.

heres a nice vid how to check your pinion angle with the 2-piece ds. didn't help me a bit with the one-piece but you can rule that out.

Some LCA relocation brackets, and adjustable lowers with that low of a drop. And and upper control arm to help with wheel hop that might be left over.
This is just one opinion.

 

Hmmm, yeah I don't seem to feel any vibration when i'm at constant speed. Yeah I need to watch that video and then check my pinion angle, i'm sure it's out of whack.

 

Thanks man, I will look into the LCA relocation brackets and the adjustable LCAs. I actually so far have not had any problems with wheel hop, if I burn the back tires a bit everything seems really smooth so I don't think I have any wheel hop
