On my loose hill climb test the Jeep performed as a Jeep should, both in stock form and lifted. If you look closely you can see the rig's tire tracks and see that it started to slip and dig in about half way up the climb. Instead of hopping and huffing and giving up, the little JK just kept working and eventually re-gained traction and walked up the hill. I was impressed that it crawled this loose hill just off idle in stock form and really happy when it repeated the performance with the lift. Many test vehicles I have worked with in the past have failed to climb this hill, even with lots of throttle and momentum.
