It should be a Fox shock, that is what I had on my XLT Xtra12, and I had the same problem with riding my girlfriend double. I finally solved the problem and got her own sled to ride!
. I have ridden double on my edge suspension, and besides being able to pull some AWESOME wheelies, have had no real problems with bottoming out. michahicks is right, though, take it to a shop that rebuilds Fox shocks, and have it rebuilt/revalved to meet your needs.
