RPM is located in beautiful Prescott, Arizona and has been manufacturing premier quality performance all terrain vehicle (ATV) axles and aftermarket parts since 1995.

Our DOMINATOR series racing axles are world-renowned and have been used by more GNC Champions than any other axle in the world.

Recently, our new DOMINATOR II axle was scientifically tested against all the other major brands of performance ATV axles and far surpassed each and every one of these "competitors" in strength and resistance against bending. Proving what the top racing champions already knew - the DOMINATOR axle is the strongest, most reliable performance axle on the planet. (Check out the results of the ATV Axle Strength Test).

When it comes to manufacturing the highest quality performance ATV parts, nobody beats RPM!
