Wilwood 170-13872 Cast Iron Parking Brake Rotor Hat for Truck SUV 4WD Big Brake Kits

The Wilwood 170-13872 is a premium cast iron parking brake rotor hat engineered to enable the use of bolt-on rotors on vehicles equipped with OEM internal shoe parking brake assemblies. Designed for big brake upgrade applications on trucks, SUVs, and 4WD platforms, this hat bridges the gap between factory parking brake hardware and high-performance aftermarket rotor systems.

Each hat is precision machined to tight tolerances and features a threaded hole design for direct use with standard through-hole mount rotors. The fixed mount construction ensures a solid, rattle-free connection between the rotor and axle hub. Following machining, every hat receives an electro-coat (e-coat) finish for durable corrosion resistance that stands up to harsh road and weather conditions.

Key Features:

• Premium grade cast iron construction for strength and durability
• Precision machined threaded rotor mount holes for use with through-hole mount rotors
• Fixed mount design for solid, reliable rotor attachment

The Wilwood 170-13872 parking brake hat is the ideal solution for builders upgrading to larger rotor diameters while retaining the factory internal drum-style parking brake. When paired with compatible Wilwood rotors and hardware, this hat delivers precise fitment and dependable performance in demanding street and off-road conditions.
