Would I have a bad pinion angle from my future LPD30, once I'm running 33's and a RC 4.5" LA lift?

Last week I bought an open, but never unpackaged or installed RC 4.5" LA lift w/ rear leafs for $800, locally (saved $700!!!). I also bought my buddy's LPD30 with a Spartan locker, USA 4.56 gears and BTF diff cover for $300. The axle, sadly, is still under his '99 XJ because he's building his original HPD30 he swapped out for the LP his brother sold him. I'll be taking delivery of the freshened up (gotta love loyal friends) axle mid-end of January.

Thanks for the help. :D

It can be done. You will need to watch castor angle vs pinion angle closely, but it has been done many times. I just did a 5" on the kids TJ with no problems

Ok. I'll run it and see how it goes. Thanks 4.3.
