For Summit 2017 REV Gen4 owners who’ve experienced early belt failure, BRP will provide, the following updates:
Gear ratio change (21 top/53 bottom)
PTO Engine Mount Shims
Those updates will be available, at no cost for the customer, on both 154” and 165” platforms.
Combined with the new belt (part number 417 300 531), they will significantly improve belt life and
lower driveline temperatures.
