Depends on the size tires. Usually good up to 33" tires. Any larger and many swap in a HP D30 for the front and a ford 8.8 for the rear. Big thing to watch out for is at the 4"~6" lift mark the rear upper control arm upper mounts like to tear off. Otherwise, they make very competent offroad vehicles. Their breakover angle on 31" tires is superior to a stock JKU rubi.
Sent from a a few tin cans and some string.
