Designed for the special needs of hardcore competition rockcrawlers, here is a cure for most of the broken U-joint blues.
The WARN Hub Fuse replaces the standard clutch ring in WARN hubs. It is designed to give before an expensive and difficult to replace U-joint. A spent Hub Fuse can be replaced in minutes on the trail with standard tools and costs much less than a U-joint.
Here's the story: The standard WARN Premium hublock clutch ring is designed to withstand over 80,000 inch-pounds of pressure, a 297x U-joint will normally break at around 55,000 inch pounds in a straight ahead condition (considerably less at an angle). The Hub Fuse is designed to work up to about 46,000 inch pounds.
Fits all 1/2 ton (3 inch) internal mount hublocks and all external mount hublocks with triangles next to the 4x4 and 4x2 on the chrome cap.
