R&P Knowledge Hub
Idler hubs support trailer wheels on axles that do not use electric brakes. A pre-greased hub kit simplifies installation because the bearings are already installed and packed with grease inside the hub.
Always verify axle capacity, wheel bolt pattern, bearing sizes, and seal dimensions to ensure compatibility with your trailer spindle.
