Going to order my OME lift today but just a quick question.

I installed 884's on mine and could not get a good alignment without UCA's. I swapped them out for 883's and got a good alignment and my truck is perfectly level with my TSB leafs (3+overload)

 

spacer took care of the front.

Measurements are listed below (hub to fender):
FD 23.0 FP 23.0
RD 23.5 RP 24.0


Will drive it for a bit...see if the rear settles.

 

After they've worn in and settled (1/2"), 1/4 tank of gas, left "-" spring is 24" and the right "O" spring s slightly over 24, maybe 1/4". Didn't know what the +/-/O thing was about till after they were installed. I'll swap sides with them at some point.
An extra 1/4" top plate spacer on the left, in addition to the originally installed trim packer, put the front level.

 

i have a fweeeee trim packer if anyone needs it
