Axle Washer

The COLEMAN RACING PRODUCTS Axle Washer (model AW-851) is a precision tanged spindle washer engineered for marine drivetrain applications where axle alignment and load distribution are critical. Whether you're running a high-performance boat with a Wide 5 wheel configuration or maintaining a trailer assembly, this steel washer sits between the axle spindle and wheel hub to absorb radial loads and prevent lateral play. Anglers and boaters who demand reliable hardware for their rigs understand that even small components like washers directly impact bearing longevity and steering response on the water.

Constructed from cadmium-plated steel, this axle washer provides corrosion resistance essential in saltwater and freshwater environments where oxidation can compromise structural integrity. The tanged design—featuring a small lug or tang that seats into a corresponding groove on the spindle—prevents rotation and ensures the washer remains indexed during assembly and under dynamic load. The wide diameter profile distributes clamping force across a larger surface area, reducing point-load stress on softer materials and extending the service life of hubs and spindles. At just 0.05 pounds, it adds minimal weight while delivering maximum mechanical advantage in the critical interface between axle and wheel.

This washer is essential for boat trailers, utility trailers, and custom marine builds that use Wide 5 lug patterns—a standard in racing and heavy-duty marine platforms. Installation is straightforward: slide the tang into the spindle groove, and the washer seats flush before the wheel assembly is secured. Technicians and DIY boaters rebuilding axle assemblies should stock this washer as part of a complete spindle kit to ensure proper preload and bearing clearance. Compatible with Coleman Racing Products axle systems and OEM Wide 5 spindles, it delivers the precision fit and durability that serious water sports enthusiasts and commercial operators depend on for safe, trouble-free launches.
