I just put an All Sports 6 inch Long Travel on my Precedent.. then installed the double action rear leaf springs..
We live on a small farm with lots of hills, ruts, and other stuff that causes problems for the stock cart.. Heck, even climbing a hill on wet grass was causing issues.
It does raise the cart up quite a bit.. took me a few days to get used to it, but now I would never go back... my cart goes almost everywhere.. and the rid is so much softer now... like riding in my wife's SUV.
