I have purchased a 2003 Rubicon and I need to lift it. I was thinking a 1"-"2 body lift combined with a super 7 stretch kit from rockkrawler.com I am fairly confident that a 3 link kit will articulate and ride better than Rubicon Express' 5.5" long arm kit. I was hoping to run 37" tires but they might be a bit much for that little straight six. I plan to eventually throw my project engine that I have been working on for the last couple of years in under the hood. I know that that 383 is getting anxious. Has anyone heard any good or bad about the rockkrawler.com kit? I have heard good and bad about the R.E. kit. What is your opinion?

I have always run 35" tires and they were not bad it's just that they seem to be borderline. Not big enough to get you out, but big enough to get you stuck. I have already done the warn conversion with my front outer so I am not real concerned about breakage. I have thrown 4.88's in both axles already and with my stock set up it really sucks on the highway. I need to lift soon. I am waiting to decide on what lift before I decide on what size tires.

Any help from you fellow jeepers would be awsome.
P.S. I am building this for a daily driver and I plan on riding mostly trails in the Rocky Mountains. I also use this for work. I put on 3000miles a month down gravel roads through farmers fields and on highways. I work in the muskeg too.

Not big enough to get you out, but big enough to get you stuck.

I think this statement could be made about any size tire.

I wouldn't go over 35's without cutting the body - so you can get away with less lift to lower the cg.

You are going to be wanting for some SERIOUS drive train beefing with either 37's or the bigger mill.
Stick with the 35's IMHO. A set of 35" x 13.5" BFG Krawlers is a heap O' tire.

I have seen only bad things from roickcrawler.. including posts here about the horrible customer service... crappy workmanship is one thing, but bad customer service is inexcuseable.
I have a RE long arm kit. its the very first kit they ever sold and it has 2 worn joints.. funny though.. they are the solid rubber mounts that wore, not the shperical ends. This kit has LOTS of off road miles on it and I drive it every day to work. it also ramps 1270 on a 25 degree ramp..thats falls into the "wayyyy pleanty" category.

I was hoping to run 37" tires but they might be a bit much for that little straight six.
not with 5.18 or 5.38 gears. I run 5.38's with 37" mtr's. 2700rpm at 65mph in 5th gear of an nv4500....the 4.88's might be perfect, but I like the loewer gears....and i dont drive on the highway a lot.

I have already done the warn conversion with my front outer so I am not real concerned about breakage

your still only going to have x297 joints up there...37's will snap them. 35's can too

why did you start with a rubicon?
