I'm gonna lift my 4 door jk soon and put. 37s on it and was wondering what everyone's opinions are on either kit. I'd like to keep the stock fenders for awhile and want it to look proportional. Please if you know of either of these lifts or have them please let me know what you think. Thanks guys
 
Are you deciding between the rock krawler coilover setup and the EVO coilover setup? Or are you looking at a regular EVO kit?
 
either way you go you get a GREAT kit. One of my friends out east has the rk 3.5 x factor long arm with the coil-overs on his 08 jk and he loves the ride. I cant say anything about the evo 4" long arm as I have not seen it in action personally but there are always great things to say about EVO products. EVO and Rock Krawler are both leading manufactures in off road suspension parts for the JK and either way you go, you will not regret it.

What's the difference between the evos? I haven't looked enough

THeres the EVO 4" enforcer which is springs and 2 front LCA and rear track par relocation and also short arm lift
EVO 4" Double D which is a basic bolt long arm system that comes with the 4" plush ride springs and shocks of your choice, or you can call and just get the kit with there coil overs
And then there is the kit eddie,GCM2 and whole bunch of other people are running that is all weld on and BA.

You can run there coil overs with any of these kits and adjust ride height to your liking. Also you can run there coil overs with just about any other system out there.
 
I am still curious since we are talking about both, if there is any advantage or disadvantage of rk's 3 link over the std 4 link setup like evo runs.
 
I'm moving to colorado next year and plan to do tons of wheeling out there. Trails and rocks mostly. I wanna have a good amount of suspension travel with a great ride on the road. I want it to be smooth on and off the trail. I don't know a ton about the different evo 4in kits but I know ill be doing serious trails.
 
I am really happy with my RK 3.5 x factor (short arm 4 link rear)

It flexes like crazy and rides great on the street. I have never wannted for a long arm kit.

Personally think running 37's with stock fenders will be a little tough as you will have to run alot of bumpstop.

I have factory painted fenders and have 3" bumps and it keeps my 35" toyoys from hitting.
 
Only problem with 3 link and 4 link systems is if you brake a control arm or mount its much more of a porblem than if you still have the standard 5 link system.

There's a big disadvantage to the 3 link and that's it still retains a track bar and it's not triangulated. There is something to be said about redundancy and if you tear off a control arm bracket as I have on more than one occasion, you still have another to get you by. If you tear off an RK bracket, you are done - trust me, I just saw this happen on Saturday.

RK 3 link drives better than stock and flexs much better off road.

In spite of what you choose to believe, the RK 3 link setup will not give you any more flex than the shocks you run will allow. As far as it driving "better than stock" goes, ride quality is 100% subjective and determined more by spring rate and shocks than how many links it has.

Yes...but don't recall see any broken control arms...you could always carry a spare if your worried.

A lot of good a spare control arm will do you if you tear off the mount on top of the axle. Just saw this happen on the Rubicon last week to one of the guys attending the JKX. When it broke, it took out his rear drive shaft, rotated his axle up and jammed it up between the gas tank. 3 winches later, a welder and a lot of work, we finally got him trail fixed enough to drag him off the trail. We have it all on video.

These weren't just average boys on the trail fixing this either. Eddie, Mel Wade, Brian from ORE and more. Most of us were looking at each other and realizing we would be screwed if this happened elsewhere.

thanks for the answer eddie, i was only curious since rk offers their stretch for a 2 door that is all basically bolt on, well seems like its bolt on. I wouldnt mind gaining a little wheel base and wasnt sure if I could do that with just longer arms or not.
 
Thanks for chiming in Eddie, I appreciate the advice. I've decide I'm gonna go with the evo 4 inch kit. Gonna order it Friday or Monday. I appreciate everyone's opinion on this.
