2.5 vs 3.5 inch lift

Hello everyone!

I am looking to upgrade my suspension. I currently have a 2inch spacer lift and 35s. The only issue I’m having is rubbing on the fenders, which was expected. I don’t do any rock crawling as I live in Michigan, but there is the occasional rock or down tree to crawl over on the trails. I really like the looks of the 3.5 and 35s but I’m not sure if it’s practical for what I do. I do a lot of 2 tracks going hunting, and just general trail riding. Nothing too major or hardcore. There is the occasional mud hole that I come across. My JKU is my daily driver so I don’t want to sacrifice too much ride quality. So I guess the question is, will a 2.5 inch lift do the job for the basic trial riding and not let my tires rub? Or should I step it up to the 3.5 inch lift? Any and all input is appreciated, negative or positive feedback!

Thank you!

if you are not rock crawling (rock crawling means different things to different people) I would go 2.5 and 255/80-17 tires. that combo will do what many consider rock crawling ie things like the Rubicon trail with no issues and do great as a daily driver. Sure big tires and tall lifts look great but if your winters are like Montana winters it is a lot nicer driving around in something like this in my opinion. I have had 4 jk's and two have had 3.5" lifts and 35's and my current one I have a mopar 2" lift and run two sets of tires a set of 35's on AEV rims and a set of 255/80-17 (33's) on stock rims. I have been to Moab many times and am going again the first week of November and will be on the the 33's this time. I doubt the will limit me much.

Your tires rubbing has nothing to do with your lift height. It has to do with lack of backspacing on the wheels or lack of bump stop. Did you add 2" of bump stop when you installed the spacer lift? Did you install new shocks? Did you install the tires on new wheels with 4.5" back spacing or add wheel adapters to the factory wheels?

I did install 2inch bump stops with the lift and have 4.5 backspacing. I did not install new shocks.

for me, 4' lifted and 35 are the best combination.

I have the Mopar 2.5 lift and 35s.. it's a beast. I have found very little I can't do trail wise and it drives pretty well around town. I go to events with the local Jeep club and of the 20 Jeeps, mine is on the more capable end.

Stick with the 2.5. It's more than you need for your described usage. You also have to start upgrading a lot more parts when you go above 2.5. (it throws the geometry too far out of wack)
