Where can these RPM beltes be purchased? Not that i'll need 1 anytime soon i just replaced mine with a gates green belt when i did the pulley/E85 swap.
I got mine from RockAuto....but that was in 2017. They were $49. Not sure today, you'll have to check.
But by far the longest lasting belt I've had on. Never had to snug the whipple aux even once in 3 years. Still holds 22psi.....no start up chirp. The graphics/lettering have dirtied a little....but I bet if I got my carpro eraser out it would shine back up with a little elbow grease.
