1 Ton Hubs Supreme

The MILE MARKER 1 Ton Hubs Supreme is a manual locking hub kit engineered for drivers who demand reliable 4WD engagement in high-stress environments. Built to the 30-spline standard, this locking hub assembly suits various 4x4 truck platforms and is trusted by law enforcement fleet operations, military transport units, and serious off-road professionals. The 1 Ton designation reflects its load rating and application scope—making it ideal for medium-duty and heavy-duty four-wheel-drive systems that require consistent, fail-safe axle lock capability.

The Supreme model operates on a manual locking mechanism, giving the operator direct control over hub engagement without electronic dependencies or delay. The 30-spline interface is the industry standard for medium-tonnage applications, ensuring compatibility across a broad range of OEM and aftermarket front axle assemblies. Manual operation means no battery drain, no electronic failure points, and instant visual confirmation of lock status—critical advantages in remote or austere field conditions. At 7.4 lbs per kit and measuring a compact 4.5 x 3 x 10 inches, the hub assembly integrates seamlessly into existing axle housings without requiring frame modification or custom fabrication.

This hub kit is essential for tactical fleets, disaster response teams, and 4WD operators who work in unpredictable terrain where power delivery cannot be left to chance. Military and law enforcement personnel benefit from the Supreme's straightforward manual design, which requires no training beyond standard vehicle maintenance. The 30-spline configuration pairs with most 1-ton and mid-size truck axles; verify your vehicle's spline count and hub bore diameter before ordering. Installation is direct bolt-on for compatible platforms, and the manual locking system delivers the torque bias needed for traction-critical situations without reliance on electronic engagement.
