Hub/Rotor GM Metric 79 & Up 5x5in BC Long Stud

The Hub/Rotor GM Metric 79 & Up 5x5in BC Long Stud by WILWOOD is a high-performance brake rotor assembly engineered for vehicles requiring robust stopping power and thermal stability. Designed for General Motors platforms from 1979 onward, this component serves law enforcement, military fleet operators, and performance-driven civilians who demand reliable braking under sustained or high-load conditions. The long stud configuration and 5x5-inch bolt circle ensure OEM fitment compatibility while providing the structural integrity necessary for duty-cycle applications where brake fade or thermal degradation cannot be tolerated.

WILWOOD's hub/rotor assembly combines precision casting with computer-optimized geometry to maximize heat dissipation during repeated braking events. The long stud design accommodates thicker caliper mounting plates and reduces stress concentration at fastener interfaces—critical for duty vehicles subject to emergency braking, towing loads, or pursuit operations. Metric dimensioning ensures compatibility with modern GM platform specifications, while the robust construction minimizes harmonic vibration and rotor runout, delivering consistent pedal feel and stopping distance predictability essential for tactical and emergency response personnel.

This hub/rotor assembly is ideal for fleet operators managing Crown Victoria, Caprice, or Suburban-platform units where braking reliability directly impacts officer safety and public accountability. Installation requires confirmation of GM metric bolt circle and stud length compatibility with your specific model year and caliper assembly. The 15.63-pound weight reflects heavy-duty construction appropriate for vehicles exceeding standard passenger-car loading, making this component suitable for emergency services, military transport, and armored or tactical support applications where thermal performance and durability are non-negotiable.
