Has anyone installed this yet? Looking to see if it nets 2.5 on a 2 door. Pics are very welcome!

From what I've read it'll be 1.5 after armor. I may have gotten that confused with the spring kits though. Email them, they're very nice and super quick in responding.

The 1.5 kit has the new triple rate springs while I have to see pricing on he 2.5 or 3.5 kit with the new springs.
 
#7 ·
oh, is that still a progressive spring? If not what is the difference? Im looking at this or the AEV 2.5 lift and trying to determine which to choose.
 
#8 ·
The triple rate has 3 different spring rates that are activated as a bigger load is applied to the spring. The progressive coils spring rate (stiffer) increases constantly as the load increases.

In theory it means that the AEV will have a continuously smoother ride and better handling since it adjusts continuously to driving conditions.

In practice it depends on how both coils are tuned: performance vs ride. AEV does a great job of balancing both and IMO it will be very challenging to beat their road handling. I've never ridden on a Jeep with RK triple rate coils but their products in general are some of the best.

Good info man thank you. I'm really stuck between aev and rk now. The new 1.5 lifts look amazing with rk. Gotta decide soon the end of month and I'm pulling the trigger

Don't forget Northridge (I believe) has the RK on sale. This is tempting but I just don't think I am ready to start voiding my warranty yet.
 
#14 ·
Bout two weeks away from my lift purchase and the 1.5 rk expedition lift kit sold by north ridge with shocks and aev dual sport 2.5 are my finalists. PLEASE help me decide which is the best option. I want great on and off road performance as well as firing 35s. I want this to be as complete a lift as i can get and also would like to avoid paying for unneeded stuff. Thanks again for any feedback.

Call RK and speak with their service Rep Jason. Hopefully he is still there to inquire more with this lift. I can't speak to this lift but with the 3.5 inch x factor there was initially more lift than advertised. This was explained by the rep stating they put more lift into the system so when the bumpers, skids etc are added and the suspension settles you get the advertised lift height. But please call them and verify that is true with this lift.

I didn't speak to Jason but Shaun was very helpful and answered my questions. according to him this lift will give me 2.5" of actual lift and would work with a 35 just right he also said due to the triple rate coils both the road ride and sagging due to weight would not be an issue. Now if I can just justify spending all that $$$$. :jawdrop:

Find a good dealership. Obviously the lift components aren't covered. Nor are damages while off-roading. But I had a little wobble when hitting a bump on either side of the front end. I took the Jeep to the dealership and they looked at everything and discovered a blown out steering stabilizer. They offered to replace it under warranty but I declined and purchased a little heavier duty stabilizer since I am running 35s (per the advice of my service manager). The dealership would have to prove without a doubt that your lift caused whatever failed. Any good reputable dealership knows this.

By the way, I am running a 2.5" RK lift and netted about 3.5-4" of lift up front on a 2 door if that helps with your decision making.
 
#25 ·
That RK 1.5 looks interesting. It would probably just about clear 35s, and maybe not while disconnected and in some situations. I may try it eventually.

Im really into the rk lift now the more I research I find myself unsure of the 1.5 or 2.5 inch kits. It seems the average is an additional inch for a 2 door but it seems hard to have faith in that. I want the right height for a 35 to have the room it needs to move and flex all that it needs to without going so high that entry is made more difficult as well as driveline and exhaust issues becoming much of a concern, my understanding is that 2.5 inches will provide that anymore will cause issues and any less will limit flex. I really wish there was more info about the 1.5 kit and some pics. Anyone have one installed yet?

Are you concerned about looks or quality? RK quality is solid and they have great customer support. Ditto for AEV if you are still undecided at all.

The RK website specifically states that you will get 1" more with the 2Dr and the what it takes to run 33" and 35" tires.

For pics just search the internet.

Absolutely concerned about quality that's why I am looking at these lifts! Lol yea only one pic with the 1.5 kit I can find is on the rk site. Just not much out there for this lift specifically yet. Only been out since December. Thanks for your input. :)

My understanding is the lift advertised on the JK site is based on a fully armored JKU. I plan on getting the 1.5 X factor as it will let me run 37's with flat fenders if I want to in the future without the expense of having to think about drivelines right away.
 
#33 ·
Yup They say i can run a 37 also. I don't think I will but that white one in the pic above looks just right to me. I can't wait. Pockets are now again empty. Time to go to work so I can get the wheels and tires next.
