More info

This is a complete kit with washers and nuts. Ends are hex shaped to allow for easy installation. The tensile strength is minimum 215,000 lbs tensile strength. These studs are the strongest available and the materials used resist corrosion and are reusable.

Depending on the trucks set-up, upgrading to a set of these A1 Technologies head studs is always recommended at anything above a stock application. They are produced from the highest quality 1722 material, making these the ultimate headstuds available. The 1722 studs are stronger than the 8740 alloy used by other manufacturers. A1 Technologies is the industry leader in fasteners offering studs for NHRA and Nascar.
