R&P Knowledge Hub
Lippert post-2020 10K “short” spindle axles use specific bearing combinations and a 4.77" pilot hub design that differs from earlier long-spindle configurations. These hubs are designed for oil bath systems and require correct oil cap and drum pairing.
Short spindle versions are not interchangeable with prior Lippert 10K configurations. Always confirm spindle style, bearing numbers, pilot diameter, and drum compatibility before ordering.
