I have a 2007 JKU X with a Rubicon Express 2" BB spacer system and twin tube shocks. I also have heavy front and rear bumpers and 33's and eventually will get a winch. I have the opportunity to get an OME 2" HD lift kit (springs and shocks) and was wondering if I could use the RE spacers still with the OME springs for a little more lift. Is that OK? Do you see any problems with that or is that not recommended? Thanks!

 

No. but with thst much lift, you should probably get an adjustable front trackbar and adjustable front lower control arms.

 

You can probably sell the budget boost for most of the money you spent on it. Then get a set of front and rear 1" teraflex spacers and keep them around till you feel your springs have sagged enough. I think adding the 2" budget boost to your lift will give you more lift than you anticipate. You don't wanna make your driveshafts mad either.

On a side note, that's just what i'd do, not telling you what to do
