A common complaint I have received from many customers over the past 30 years is:

“I replaced the drive belt on my sled with a new one and now it bogs off the line or really doesn’t run right”.

What I’ve found is they bought an after market belt or tried to save money and bought a (cheesy) cheap belt.  The exact width, length and most important rubber compound is VERY important to how the clutch will grab off the line and shift.

I HIGHLY recommend that you run a stock factory drive belt on your sled, there are just too many variables with an aftermarket and your performance will likely suffer.
