Hub L/W 13/15 Straight Shaft No Rotor Mt

The Hub L/W 13/15 Straight Shaft No Rotor Mt by WELD RACING is a lightweight racing wheel hub engineered for high-performance vehicles requiring precision wheel fitment and minimal rotational mass. This straight-shaft hub assembly is purpose-built for dedicated track applications, road racing, and extreme motorsports where every fraction of a pound matters. Fabricated to WELD RACING's exacting standards, this hub eliminates unnecessary weight while maintaining structural integrity critical for sustained high-speed driving and aggressive cornering loads.

The straight-shaft design of the Hub L/W 13/15 provides a direct bolt-on mounting interface without the complexity of rotor integration, allowing builders to customize brake system architecture independently. The 13/15 designation refers to the dual-bolt-circle compatibility (13-inch and 15-inch patterns), offering flexibility across multiple wheel rim geometries common in open-wheel and club-level racing platforms. Weighing just 6.25 lbs, this hub reduces unsprung mass at the critical contact patch—lowering brake fade, improving suspension response, and decreasing overall vehicle inertia. The no-rotor mounting configuration allows use of aftermarket or specialized brake rotors matched to specific cooling and friction requirements.

This hub is ideal for motorsports enthusiasts, race-prepped street cars, and weekend warriors upgrading independent brake systems on custom-built platforms. Compatibility spans vehicles running custom fabricated uprights or specialized spindles common in tube-frame racers, vintage race cars, and performance builds where OEM hub geometry doesn't apply. Installation requires verification of shaft diameter, bolt-hole alignment, and rotor mounting surface preparation—consultation with your suspension engineer or race fabricator is recommended to ensure proper assembly and torque specifications for your specific application.
