Advance FAA Wheel Stud RF21 Hub Pilot

Advance FAA Wheel Stud RF21 Hub Pilot

The Advance FAA Wheel Stud is a critical fastening component used on the front steer drive axles of front discharge concrete mixers, including Terex Advance and Oshkosh models. Designed specifically for hub-piloted wheels on Meritor MX23 and Marmon-Herrington RF21 axles, this stud ensures secure wheel fitment under the extreme load conditions of a fully loaded mixer. Replacing worn, stretched, or damaged wheel studs is essential during routine brake or hub maintenance to prevent wheel-off incidents and maintain safe operation. It is manufactured from high-strength steel to withstand the high torque requirements of heavy-duty mixer applications.
