Mine doesn't mention the need of spacers. However, it can't hurt to give that a try. Although it is already higher than I'd like it, I guess another half an inch couldn't hurt.
Yeah, I don't really want make mine any higher either. I already added spacers between the seat and the suspension so the the kill switch had enough room, and with the seat in the middle location, the bars hit the arm rests when I go into reverse. I'm on the shorter side and don't like the seat all the way back, so i guess I just won't be using the armrests after installing the slide rails also. It will be worth it if it saves my back though![]()
