What is the purpose of a rotor hat?

A rotor hat is the central part of a 2-piece brake rotor. It connects the brake rotor disc to the wheel hub assembly. This hat is specifically designed for larger brake kits on trucks and SUVs.

What does the '1.55in Offset' mean for installation?

The offset refers to the distance between the mounting surface for the rotor and the mounting surface for the hub. This specific offset is critical for ensuring your brake caliper aligns correctly with the larger rotor diameter.

What type of rotors are compatible with this hat?

This Wilwood Hat-TC is designed to work with standard through-hole mount rotors. You will use separate hardware to attach the rotor disc to the hat.

Product Details

If you're upgrading your truck or SUV's braking system with larger rotors, you'll need a solid hat to mount them to. This Wilwood Hat-TC is designed for front applications on vehicles with 8-lug hubs, specifically those with a 6.50-inch bolt circle and a 10.75-inch rotor mount pattern. It features a 1.55-inch offset, which is crucial for proper caliper alignment with the larger rotor assembly.

Wilwood precision machines these hats from strong aluminum alloys, focusing on keeping the weight down without sacrificing strength. The flared bell configuration and strengthening ribs add rigidity, which is important when you're running bigger brake kits on heavy-duty axles. The threaded rotor mount holes mean you'll use standard hardware to attach your through-hole mount rotors, making for a straightforward assembly process.

This hat is a key component for building a custom big brake setup on your truck or 4WD vehicle. Ensure your caliper bracket and rotor selection are compatible with this hat's offset and bolt pattern for a successful installation.
