Stock Rubicon what size spacer to level up

[Ct_Formula]

Hey All,

I've crawled all over the forum and now that I'm completely baffled I just had to ask. We have a STOCK Rubicon coming in and what spacer will kick up the ront end to level her off without having to do a bunch of things to keep her driving properly?

Never going to do a bumper or winch (wives grocery getter lol)

You should consider the longer Mopar lift LCAs to get caster in the 6 degree range, Rubicons use the same LCAs as the lower Sport/Saharas so the caster is in the 4 to 4.5 range, not enough to track well at hwy speeds. If you want a bit more lift in front you can add a 3/4" coil spacer, I used the Rugged Ridge (it lists for a JK model but works fine for the JL too). If you add that additional 3/4" spacer your caster will for sure be too low (probably in the 3.75 range).
And here's an install post I made on the LCA swap.

Teraflex JL 4dr: 1.5” Sport ST1 Spacer Lift System – No Shocks
SKU 1165000 for 4 door and they make a kit for 2 Door SKU 1165002. Comes with longer bump stops.
4 Door version 2" front 1" rear comes out nice and level, 2 Door version is a little different because the come lower in the rear from factory. Have the system on my JLUR and it is solid

Thanks B! I'm all over it, thanks for the repost I have no idea how I missed it.
