The Refurbished Gorilla Axles, or as we like to call them, "Refurbs", are nothing more than used Gorilla Axles built using used parts. Not every part of the axle is used, but MOST of it has either been lightly used or returned for various reasons. In most cases the "bell" housings and the axle bar are used, but the internal parts of the housings are new. The "Refurbs" come with a 30 day warranty and are guaranteed to fit and function just like a brand new Gorilla Axle. Other than having the splines painted a bright color (can't be seen when installed), they look identical to a new Gorilla Axle. If you do not see your application listed please call. Refurbs are NOT available in custom lengths or for extended lifts.
