Crafted from premium grade aluminum alloys, these hats deliver high strength and low weight, ensuring optimal performance without adding unnecessary bulk. Designed to fit a variety of vehicles, including OEM four-lug axles and racing hubs like those used in Grand National stock cars, these rotor hats are versatile and reliable.
Featuring a straight bell construction with a flanged rotor mount ring, Wilwood’s HD Series hats incorporate through holes compatible with threaded-hole 8 x 7.62-inch mount rotors. This design maximizes radial clearance between the caliper and the hat, which is especially critical when fitting large calipers within smaller wheel diameters. Many of these hats also support multi-lug wheel patterns, enhancing their compatibility with custom or aftermarket wheels. Some units can be ordered blank for custom axle building, making them suitable for a wide range of custom applications.

Whether upgrading an existing brake system or building a custom setup, the Wilwood Pro Street Series rotor hat ensures a secure fit, durability, and performance.
