Generally you go by lift height, how much bump stop and the shocks compressed lengths. The manufacturers listed spec means little. The 29/30's are common for 2.5 and are around a 9-10" travel shock. on a 2 door that nets say 3.5. The 31/32's are the better choice if you want/need the longer travel.
The 31/32's are around 11" in travel and about 2" longer at their compresses length. They can be run at 2.5 with 2-3" bumpstop.

2" Part# RS999328
4" Part #: RS999329 / RS999330, RS999331 / RS999332

Do they not make a shock for 2.5" lifts for this model Jeep?

I'm looking to put together a 2.5" coil lift (RK's) and I really like what I have read about the RS9000XL adjustable shocks.

If they don't make them or none of these can be used, is there another comparable make/model? Recommendations for adjustables around the same price.

Thanks

Yeah it's not like running 37's is some kind of new concept, Ha, with the lift you have proper wheel back spacing, trimmed pinch seam
And trimming sliders there should be no issues......

They told me they would work with me on both the tires and the tire carrier.

They better stand behind it. Luckily I had them print new orders when I made the changes so they have no right to do what they did.

Jeep looks good though
Jeep looks cool. Looks to me in the side view pic like if the slider was trimmed in rear 37's would fit easy.
Maybe 4wparts didn't want to mess with.....hmmmm.

First, I hope you get well soon.
Did you agree to the 35's ? That's some BS.

kjeeper10 Edit: Good post btw ^^
We can do our best to make it work.

Can you post the kit you have ? Rc is not terrible, some of the ways geometry is corrected I don't prefer. Did it include control arms ?

I don't plan on doing any off reading until marchish due to the weather so it would give my ample times to replace CAs and or DSs
Here are a couple of thoughts.
How much experience do you have Jeeping? The stock vehicle does a lot of cool stuff right off the showroom floor...
Have you talked to anyone running the lift you bought?
4" is a lot of lift for a JKU - what tire size are you targeting? why jump in to a 4" lift? Have you considered something a little less involved and less expensive? Such as. 2.5 (can fit 35 " tires with less expense or 37" with cut/flat fenders)
What kind of wheeling do you do/want to do?
RC is not renowned for their high end quality and often in Jeep lifts cheap initial costs end up costing a lot more in the long run.
What does the RC track bar bracket do? Is it a frame side or axles side- consider an axle side bracket to raise the roll center and make the Jeep drive better.
If you do intend to go forward with this consider some type of caster correction either control arms or control arm geo brackets in the front and keep an eye on your front drive shaft - it will eventually fail.
Depending on year, Watch the rear pinch seam - it can bite your tires. You can trim pretty easy.
What are you doing to relocate the exhaust so it does contact the driveshaft? exhaust spacers or replacement pipes are the standard approach but you can have someone fab something too
If you are going to wheel with big tires consider gusseting the front axle and start planning to replace ball joints.
Not busting your chops but seriously consider researching, planning, and building your Jeep in deliberate phases. This helps you shake out issues more easily without costly, diagnostic wild goose chases. Good luck

The pinch seam should be trimmed regardless. With a 3.5 you should be more than fine. I agree in the adjustable LCA for the rear, that will let you center your rear in the wheel well. I'm planning to add a 1-2.5" kit this summer. But I'm rolling fine just now.
At my local 4wd in dallas they are two things

1.) Dicks
2.) Dummies

They said the tire would hit the sliders and I told them to trim or I would trim. They then told me that wouldn't be enough and I would have problems up front also. They were pretty adamant that I just go with 35's. and suggestions? I really like the 37's and had budgeted for the extra for re-gearing and other more expensive items. Before I give up let me know. Im kind of thinking add a 1 inch body lift.

Nice level stance. Looks great

Yep ... aka spacer lift. These are just spacers that range 3/4" to 2.5" that install on top the factory coils.

Also dont forget to get quotes from WF vendors and local shops. I was able to score my RK X Factor at 25% off through a local shop rather than waiting for a sale. And they just beat one of our WF vendors by a little bit.
