I have a 2 door 2014 JK with 2.5" Rock Krawler lift and their recommended Bilstein shocks. I'm running 37" BFG Krawlers at about 5psi on the trails. The setup works great around town (at closer to 30 psi) and highway and fine on the trails except in one situation. If I'm on a steep slope and have to use momentum to get up it and hit a small ledge the front end comes up off the ground. I've experienced this same problem with other 4X4s and other lifts. What if anything can I do to mitigate this problem? I'm not trying to do it on a budget I would even go to coil overs if that would help. I'm getting ready to go to a 4.5" lift so would like to address this problem at the same time.

If you have a lot of weight on the back try lightening the load. Full size spare with bead lock, tire carrier, heavy bumper, extra fuel, high lift, etc. If you have all of those then your front end will come up very easily. If you have none of those, then more wheelbase as has been posted.
Btw I would think more lift will make it worse not better...
It is just weight transfer plus a bit of twist from rear axle torque. A 4 door will be slightly less prone to lifting the front end but basically even with long arms or a longer vehicle this will still happen if you give it enough berries when going uphill.
I found firmer rear coils (and i guess a firmer rear swaybar) can help slightly but the reality is that the Jeep wants to lift its front left wheel under acceleration even on flat ground, so the best way to handle the issue is to drive while knowing it will lift from that corner first.
when you go to the x factor, you will have all 4 control arms and be able to extend the wheel base a bit even with short arms (not much but alittle). This will help.
what other "armor" do you have? do you have a winch?
From personal experience, i have a 2.5 inch max travel, and heavy rear with tools and bumper/spare , but with the weight of my flares , bumper , and winch up front, i park on a hill nightly and dont have any issues.
