Uppers will be the same as our current X factor adjustable arms, same part numbers and all.
The single adjustable TB's will be a great addition to our line and I'm very excited to have them out.
In addition to all of that, we will have 4.5" 4 door springs very soon and will offer it in both a mid arm and long arm application for JKU's as well as a 5.5" long arm for 2 doors.

I understand that advertised height versus actual height can be two very different figures. I am considering one of the 2.5" kits for my 2015 JKU (either Flex or Adventure 1). I have Smittybilt XRC front and rear bumpers, a 9500# winch and HD tire carrier with 33" tire. Just over 200# additional front and rear. What kind of height can I expect from either of those kits? Also, with the non-adjustable control arms in the Adventure 1 kit, if the actual lift ends up being higher, is there a problem with a low caster?

The RK coils will sag with that weight. I'm running a roughly equivalent build, probably even lighter, and there are stock Rubicons that sit at the same height. My coils have a significant amount of rust too. RK suggesting painting them but really didn't offer the insight that they were having issues with their paint.

When doing the trail gunner install we had a coil that was standing on end fall over on the concrete floor that caused significant amounts chipping in the coating. RK might want to look into whoever is doing their finishing and pick a more durable coating.

Its difficult to estimate due to not knowing how that extra 200# is distributed I would believe that you should be right at the 2.5" mark. If you end up a touch higher, it will not be an issue as the front lowers are made to be slightly heavy on caster at 2.5", and slightly light at 3.5".

Aside from the lift not being lasting, I've got diminishing ride quality as the coils age- only a couple years old with mostly daily driving. I'll be selling my coils soon to someone looking for more of a leveling kit and less of a lift kit.

Correct, 2.5" springs won't give you a lasting 2.5". I've got a 2dr but when I pull out the rear seat (75lbs over the rear axle), you can see the vehicle pick up. Pulling off my spare tire (315 bfg all terrain w/ stock wheel) also nets a notable gain.

The lowers length isn't available to me yet but the engineers statement was that they will be slightly longer than our 2.5 X factor lowers would be. As soon as numbers are available, I will post them.
Uppers will be the same as our current X factor adjustable arms, same part numbers and all.
The single adjustable TB's will be a great addition to our line and I'm very excited to have them out.
In addition to all of that, we will have 4.5" 4 door springs very soon and will offer it in both a mid arm and long arm application for JKU's as well as a 5.5" long arm for 2 doors.
