UFP Stainless Steel Spindle Wear Ring – Fits 3,500–4,200 lb UFP Axles
Replacement stainless steel spindle wear ring designed for UFP (Unique Functional Products) trailer axles rated from 3,500 lb to 4,200 lb. This wear ring provides the sealing surface used by the hub grease or oil seal.
This component is intended only for axles that originally came with a factory-installed wear ring.
R&P Knowledge Hub
UFP axles are commonly used on many boat trailers including brands such as EZ Loader and Ranger. One identifying feature of UFP axles is the axle nut retention system, which uses a flat axle nut covered by a thin stamped steel “bottle cap” style retainer secured with a cotter pin.
All UFP axles in the 3,500–4,200 lb range typically use a 1.68" grease or oil seal. If your axle does not use this seal size or does not have the bottle-cap style nut retainer, this sleeve likely will not fit your axle.
This is not a repair sleeve or seal saver. It is a replacement for the original wear ring installed on the spindle.
Installation requires cutting off the existing sleeve and installing the new ring using the inner bearing as a mandrel along with a short section of pipe or similar tool to evenly drive the sleeve into place. Previous mechanical experience is recommended.
