Previous owner installed the 3.25 lift in my TJ. It's probably 2 to 3 years old now. Coming from a leaf sprung cj5 it hard to know if it rides rough. I like it alright. I wheel some moderate stuff and haven't had any complaints yet. I'd say for light duty, fire trails and to support 33s it would be ok. I've read a few forum posts that say the springs are ok, but replace the shocks eventually.
Before you pull the trigger search out Zone lifts. Lots of great opinions on their lifts, and the pricing is good.
