This kit includes premium wheel bearings with heavy-duty steel seals and 100% 304 stainless steel axles. If your machine requires wheel bearings, it is very important to check the axle for wear or rust. Factory axles are much softer than bearings, and it's likely the old bearings damaged the axle. Axle damage, rust, and wear will significantly shorten the life of replacement bearings. HD switch axles are made from hard, seamless 304 stainless steel (304SS) that will never rust. 304SS is stiff, sturdy, and will last much longer than the soft carbon steel factory axles. Our bearings are world class quality and use durable steel seals.
