ARP, the world leader in fastener technology has just released a new Pro Series main bolt kit manufactured from "Austenitic stainless steel" material FA20 engine.

Includes a set of ten main bolts, six case bolts, ten parallel ground washers for the application and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. ARP employs a special age-hardening process prior to thread rolling and machining that greatly improves fatique life and delivers 230,000 psi tensile strength.

Best of all, the Austenitic stainless material is immune to rust, corrosion and hydrogen embrittlement when submersed in a water jacket or coolant based environment.

Optimum design, enhanced reliability, and increased strength are the main attributes of ARP's Pro Fastener Series fastener kits.
