RPM has added a new product for you Helion Volition and Criterion owners – a set of rear axle carriers. These new carriers have been beefed up with more material for strength as well as using a 5×11 outer bearing instead of the stock 10mm bearing. Although they have been modified slightly from the stock parts, they retain the same geometry and are a direct fit.
#73692 Oversized Rear Axle Carriers for the Helion Volition & Criterion – $9.95/pair
