Fitment & Compatibility

Match the specific application and confirm that any aftermarket upright or hub retains the manufacturer's required geometry. Check hat seating, rotor position and caliper centering using the supplied assembly instructions. The wheel must clear the caliper over its entire spoke and barrel profile, not only at the rim opening. Route the flex lines through steering lock and suspension movement without strain, then check pedal travel and proportioning with the existing rear brake system.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
