This stout brake hat is carved from a solid piece of 6061 aluminum.  It has been tested and approved through the tortures of The World Famous Baja 1000 on The Hall USA Trophy Truck.  We made this hat to run on Spidertrax Ford 1 ton Unit Bearing hubs with Wilwood Rotors but it could be usefull for an endless number of applications.
