For a Sno-x version you would use the 075 or the 070 that it replaced. They are the same exact size & length but the 075's are cut at a new angle for durability. Both are longer than the X-country ones which are the 076 and the 066 it replaced. Again these to are identical belts,except the new angle cut of the 076 for durability. Off hand if I rember right the 075 & 070's are approx. 3/4" longer than the 076 & 066. The reason being is for sno-x you want a longer belt to work better on the starts (better low-end). Then on the other side of the coin, the 076 & 066 are shorter for X-country (better top end speed). Either way you can use any of these 4 belts in your Sno Pro, but depends on what you are using the sled for. Then depending on which one you go with , you would simply have to just change the belt deflection on your TEAM secondary clutch accordingly to work with the longer or shorter belt. Hope this all makes sense and helps you out!
