Wilwood 170-15803 Disc Brake Rotor Hat for Truck SUV

The Wilwood 170-15803 is a high-performance disc brake rotor hat designed specifically for truck, SUV, and 4WD applications. This precision-machined component serves as the critical mounting interface between your vehicle's hub and the brake rotor assembly, enabling big brake kit upgrades on heavy-duty axles.

Key Features:

• Precision CNC-machined from premium aluminum alloy for exceptional strength-to-weight ratio
• Threaded rotor mount holes for secure attachment of standard through-hole mount rotors
• Flared bell configuration with strengthening ribs for maximum structural rigidity
• Engineered for 6-lug and 8-lug truck and SUV axle configurations
• Lightweight design reduces unsprung weight while maintaining durability

Wilwood's truck rotor hats are essential components for custom brake system builds, allowing you to adapt high-performance rotors to your vehicle's existing hub pattern. The threaded mounting design ensures reliable rotor retention under demanding conditions, while the ribbed construction resists flexing and maintains proper rotor alignment during hard braking.
