I raised mine 6 inches but it is not the gorilla lift. I made this in our machine shop. I like it for the clearance. I feel like I am going lower mine back down a bit due to the steep inclines that I spend most of my time on. The biggest reason for lowering it a little is that now on hillsides I keep cacthing the top on trees where before I never did. The ride is pretty much the same as before. My suggestion, I would use a 4 in. but set the alignment up right. Sorry to say this but most of the xp's I have seen are totally out of alignment. Just remember different terrains take different alignments. have fun
