Q:Why doesn't Ski-Doo offer any replacement parts for the HPG shock absorbers? It would be really nice to be able to buy sealheads and shafts to fix a bent unit, instead of a complete shock. They are GREAT shocks, better than most OEM, but the lack of parts makes things tough. - AmSnow.com user Nitro169
Ski-Doo engineers answer: We do offer a tremendous number of parts for our HPG shocks. Unfortunately, due to the large number of part numbers required, we don't stock every shaft or seal carrier possible. Each year we strive to increase the number of parts available for them and the items you've mentioned are being considered. Thanks for the input!
