Wilwood big-brake rotor hat engineered for truck and SUV applications features a 1.5 in short offset with a 12.0 x 8.75 in bolt circle and 4.255 in center register; the hat uses threaded rotor mount holes for through-hole mount rotors. Truck hats are machined from premium aluminum alloys and include strengthening ribs on a flared bell for added stiffness. These hats support big rotor brake kits on 6- or 8-lug axles and prioritize reduced weight while maintaining mount integrity.
