The Wilwood Hat Brake Rotor 4x4in BC 6x6.25in Rotor BC (SKU: WIL170-15920) is a precision-engineered brake component designed for high-performance 4x4 vehicles and off-road tactical applications. Built by Wilwood, a manufacturer trusted in motorsports and heavy-duty brake systems, this hat rotor serves as the hub-mounted interface that couples your vehicle's wheel assembly to the braking system. Whether you're running a custom off-road platform, a tactical support vehicle, or upgrading a high-demand brake setup, this rotor ensures consistent thermal dissipation and reliable stopping power under extreme conditions.
Constructed from aluminum with black paint finish, this brake rotor hat features a 6x6.25 inch bolt pattern for the rotor interface and a 4x4 inch wheel bolt pattern for hub mounting, with a 0.725 inch offset and 3.130 inch center bore. The aluminum construction provides superior heat dissipation compared to steel, critical in tactical or demanding off-road scenarios where repeated hard braking generates significant thermal load. At 1.15 lbs, this component is engineered to minimize unsprung weight while maintaining structural integrity—a key performance factor in vehicle handling and suspension response. The black paint finish resists corrosion and maintains appearance through mud, salt exposure, and harsh environmental conditions typical of operational deployment or remote terrain.
This Wilwood hat rotor is ideal for operators and fleet managers maintaining specialized 4x4 platforms, including tactical support vehicles, expedition rigs, and performance off-road systems. Installation requires compatibility verification with your existing Wilwood or universal brake kit assembly—confirm both the rotor bolt pattern (6x6.25 in) and wheel hub pattern (4x4 in) match your vehicle's specifications before purchase. Technicians and vehicle builders will appreciate the precision tolerances and Wilwood's reputation for quality, ensuring proper rotor seating, balanced thermal performance, and extended service life in field conditions.
