5100 / Eibach Coils / ICON AAL / Non-TSB 2+1 / ARB Bumper - how level will I be?

Hi all,

Been scouring the forums all day looking at various threads trying to find the ultimately answer to this question, and while I found bits and pieces, I never found a conclusive answer.

I was denied the TSB leafs today as part of the vibration TSB b/c of my ARB bumper (uh huh), so that threw me for a loop.

I found a member on here who had an ARB bumper, 5100s up front on the Eibach coils and the TSB leaf pack. With the 5100s @ 0, his truck had an almost stock rake to it. With the 5100s at 0.85, he was basically level, if not a smidge nose high with the TSB leafs. A 1.5" AAL brought back the OEM style rake.

My understanding is the TSB leaf gives you anywhere from 0.75-1" in the rear over the factory 2+1 leaf.

I had originally thought about going with the 5100 on O/R coils @ 1.75 w/o something in the back to level, but reading a lot on here it appears the O/R coils aren't suited well to compression which is why I'm going with the Eibach setup. Those coils should give me 1.6" @ 0, 2.4" @ 0.85, but I have the bumper which already weighs me down approximately 1" over the stock truck.

Using the logic of the aforementioned member's truck, I'd venture to say 5100s @ 0.85 with a 1.5 AAL should give me a slight rake, right?

I would assume the 2+1 w/ Icon 1.5" AAL with the overload in place would be taller than the TSB springs, no?

Lastly, 3" seems to be the threshold for UCAs, and I have read 5100's at 2.5 get into UCA territory. With the weight of the ARB bringing me down, I'm assuming I'd be within spec, but obviously I'd drop to 0 if the UCA issue came into play.

TL;DR

- Eibach w/5100 @ 0.85 + ARB with ICON 1.5" AAL on non-TSB - Level or nose high? - suspect I'd be level, but confirmation would be nifty.
- UCAs needed? - I don't think so but confirmation would be cool.

Thanks for reading.
