I'm Running 4" net from my piecemeal of parts I call a lift. 315/70/17 is about 34.5" With flat fenders I have no rubbing at Max Flex. I was rubbing on stock fenders with a trimmed pinch seam. I have about 6" or a little more of flex. I would recommend a 3.5" lift If your planning on going bigger in the future.

I run a 2.5" lift with 35s. Had to do just a small bit of trimming the pinch seam because of rubbing when aired down (tires bulge out on bumps). You'll have better reliability if you don't go any higher unless you'd like to do other mods.

Going higher can get you more out of the muck in deep holes--your electronics may appreciate that. Mud/sand will be very hard on your Jeep--anticipate brake caliper problems, bearing failures, damaged axle seals, even ground down axle shafts (at the seals)--I've experienced it all running quicksand-filled rivers here in Oklahoma. But, other than running large enough tires to get your axle shafts higher, you're at the mercy of the elements.

There is a sticky by Dirtman called "My thoughts on lifts". It is a very informative read--highly recommended. Good luck with your decision.

I just wrapped up the AEV 2.5 lift and spacers..yeah i know.. spacers..eh... anyway I am 6' am think the 2.5 is a pretty modest lift. I would have liked to go with a 3.5 but it's all good, I can still put 35s on it! I bring up my height because when i got back home after doing the install I kinda forgot how much further it was off the ground and rolled my fat ass right on out and on my face lol. SO yeah.. it's a bit of a change, not too bad imo.

If you break it, that's just an excuse to get an upgrade!

Here's my 2 door with a RK 2.5 and 37s

Flexy

I started with a 1" coil spacer lift. After a few months I replaced it with a 2.5" proper coil lift. Then, a few weeks later I took my spacer lift and added it to my coil lift. So, I'm at 3.5" of lift now. I know I am risking damage to my drive shafts, but it's a risk I'm willing to take and I can handle the repair expense if I need to.
My advise is to go 3.5" if you can afford to replace broken parts. Otherwise, stay at 2.5".

I started with the teraflex leveling kit then moved up to the RK 2.5 max travel system. I have been contemplating throwing one of the 1" spacers from the leveling kit up front as, to my eye anyway, there is still a slight rake. Problem is I think a full 1" will create a rend end low look. Anyway, might put a 1" spacer on both ends to get a bit more height...just for looks really. Have you had any issues? I know the known issues but did it change the on road mannerisms much? I will not do it if it does, the RK kit handles the road really well. I have an unlimited btw if that makes a difference.

Flexy

I just added the spacers a couple weeks ago, so I don't have a ton of experience with this setup. The road handling seems to be the same. I do stumble getting in more than I used to!
You probably know this already, but you can get a 1/2" or 3/4" spacer for the rear if you are concerned about rake.

Thanks. Yeah, I know I can get smaller spacers, just wanted to try and use stuff I had in the garage.

does the drive shaft damage come from daily driving or off roading with the lift?
