Niche 1216 is a new heavy duty Forged Billet Aluminum Axle Carrier. This Bearing Carrier includes two double-wide heavy duty Bearings which will outlive and outlast other twin row Bearings on the market, hands down! Our carrier is machined from forged 6061 billet, a high grade aluminum. There are many Carriers on the market, however 99% of them are not forged, which is crucial to the strength of the metal. All Carriers show up ready to install with two Bearings, two seals, a precision machined spacer and a center-mounted zerk fitting making it easy to grease and go! This unit is plug-and-play fit for your machine and works perfectly with your stock axle o-ring. We offer a lifetime warranty on the forged Carrier and one year warranty on all internal components!
