These specialized drivetrain components represent a significant modification to conventional axle designs. Instead of the axle shafts being centered with the wheel hubs, gearing within the hub lowers the axle’s relative position. This configuration provides increased ground clearance without requiring larger tires or suspension lifts. This is particularly valuable in off-road applications.
The enhanced clearance contributes to improved obstacle negotiation and reduced risk of undercarriage damage in challenging terrains. The gearing at the wheel hub also reduces stress on other drivetrain components, such as the axle shafts and differentials, potentially extending their lifespan. Historically, these systems were initially developed for military vehicles requiring exceptional off-road capabilities, and their adoption in civilian applications has grown, especially among enthusiasts and professionals seeking superior performance.
