Starlite 55XD Hub Rear 5 Bolt Drilled Studs

The Starlite 55XD Hub Rear 5 Bolt Drilled Studs by WILWOOD represent precision brake hardware engineered for serious performance builds and high-demand track applications. These rear hub studs are purpose-built for vehicles requiring robust, reliable fastening solutions in extreme braking environments where standard hardware simply cannot perform. Whether you're upgrading a street-legal track car, a dedicated race vehicle, or a heavy-duty truck with serious stopping power demands, the Starlite 55XD delivers the metallurgical quality and dimensional accuracy that professional mechanics and fabricators depend on.

WILWOOD's Starlite 55XD studs feature drilled geometry that optimizes weight distribution while maintaining structural integrity under repeated thermal cycling and high g-force braking loads. The five-bolt pattern accommodates modern brake rotor designs and ensures even pressure distribution across the mounting surface, critical for eliminating lateral runout and vibration. The studs are manufactured from premium alloy steel with precise threading and head geometry to guarantee proper seating with your WILWOOD or compatible aftermarket wheel hubs. This design philosophy prevents stud stretch, rotor wobble, and the catastrophic failures that can occur when inferior fasteners are exposed to sustained high temperatures and repeated deceleration events.

These studs are ideal for drag racers, road course competitors, and performance truck owners who have invested in complete brake system upgrades including WILWOOD hubs, calipers, and rotors. Installation requires proper torque sequencing and fastener preparation to maximize clamp load and prevent galling; experienced fabricators will recognize the importance of quality hardware at the foundation of any serious brake system. The Starlite 55XD's compatibility with standard five-bolt rotor patterns makes it a direct upgrade path for enthusiasts transitioning from OEM fasteners to race-grade components. At 8.65 lbs and compact dimensions, these studs integrate seamlessly into existing rear axle assemblies without requiring adapter plates or modification.
