This is the original transformation of my 2002 shortrack viper to a 141". The kit used was from Hartman inc. and was very well built. I am still tryin different rear skid setups for the best ride but overall very impressed with the mod.

over 7000 miles on sled since the longtrack kit, about 9000 miles total... I ride in the UP around marquette, sands,skandia, and big bay...all backwoods, no trails. The snow up here is great and the boondockin' is the ultimate.
