  HATS
  SIERRA hats are made from aircraft quality aluminum. Our goal is to make them the lightest and strongest available. Our hats provide greater air flow to the outer face of the rotor so temperatures are kept to a minimum. All are available fully machined, but undrilled. This allows you to match virtually any hub and bolt pattern with our wide selection. Hat Diagram Hat
