I have a ZRT 800 that I haven't ridden in 2 years, because it is now a back-up sled but I would like to keep it in top condition. This Cat has 12,500 miles on it, and still runs like a raped ape. 2 years ago coming across the ice bridge from Ontaio to Drummond Isl. USA, I was jumping some drifts coming across Lake Huron and cracked my rear shock in 2. My buddy put M-10 on his Cat and had a spare skid in his barn, his Cat was a 2001 with Cat shocks instead of the Fox shocks I had on mine. I took the shock and placed it my skid, but there is nothing left to it, I need to have it rebuilt, can anyone recommend anybody.... Thanks.
