Does anyone have any experience with these? Are they worth the $? Do they keep the belts cooler? I ran 800 km on a belt this year on my 08 154 and when the snow got hevier this spring I blew 2 belts in one day. I think the hevier snow and higher torque needed to go thru the hevier snow is flexing the clutches. was looking at a racerworks brace. any input is appreciated.
