I just purchased another JK and I just can't decide. Rusty's mid arm 3.25 radius arm lift or the Rock Krawler 3.5" mid arm X flex. I will be running 37's. We wheel pretty hard once a month but the rest of my time is on the road since she is a DD so on road is important too. Thoughts????? Good or Bad welcome.

 

I have the RK 2.5 flex and I like it. Its the same components as the 3.5, but with shorter springs. Only issue I have is that my tires touch the LCA when full locked. I street ran 35's on a TF leveling kit before switching to RK and it didn't touch the stock LCA. I got the right back spacing on my wheels and tts not bad, but its rubbed a shiny spot on my arms. It wheels great offroad though. I've got plenty of flex, but now I wish I had an extra 1/2 inch on the lift. I had some kids riding with me and we hit a washboard road at 45MPH. One of them said, "wow this is a great suspension" because it was smooth at that speed on a dirt road.

 

Rock krawler without a doubt!!!

 

Simple just go RK

 

Congrats on the purchase!
If you have any questions feel free to ask.

 

I plan on this being the only kit for this rig (LOL) and just want to make sure I'm getting everything I want. I know forums can be one sided so I'd like to here why you think RK. I really like the idea behind the radius arms and was planning on going that route. Anyone had problems with either setup?
Rusty, does this sit at a 4" height or less? My current rig is at 4" and I don't want to lose clearance since she is a JKUR. I know the RK is more on the 4" side.

 

Rock Krawler, without a doubt. They make awesome stuff.

 

I'd speak directly to the manufacturers to get their feedback on what sets their lifts apart from others. Yes, you'll get biased information from the manufacturers but most of us here are going to push the lifts we have to justify our own purchase. So not really unbiased unless someone has run both and can comment on strengths and weaknesses.

A few people have run multiple lifts but 99.999% will be something like TF/RK or RC/RK or something like that. And it will be a basic lift first with full lift second. Not a good comparison. I have yet to see the comparison you are asking so I think you will be one of the first to look at these specific kits head to head.

 

Both are good lifts honestly. I have no experience with Rock Krawler personally, but hear nothing but good about their products. As far as Rusty's, I have nothing but good to say about the things that I have ordered from them.

 

I have the RK 3.5 mid arm lift with Bilstien 5100's. Its rides awesome on and off road. RK has my vote!!!
