Product Details
If you're upgrading the front brakes on your truck or SUV with a big rotor kit, you'll need a solid hat to mount those rotors. This Wilwood Hat-W4A is designed specifically for that purpose, using a 6 x 5.50 bolt pattern and a 9.19-inch bell diameter to accommodate larger brake rotors on 6-lug axles.
Wilwood machines these hats from premium aluminum alloys, which means they're strong enough for heavy-duty use but also help minimize unsprung weight. They feature threaded holes for standard through-hole mount rotors, making installation straightforward. The flared bell configuration and strengthening ribs are built to handle the demands of larger brake systems on trucks, SUVs, and 4WD vehicles.
