for standard con rods - made of high grade 8740 chrome moly steel and heat treated to a nominal tensile strength of 200,000 psi. Threads are rolled after heat treat to ensure optimum fatigue strength
ARP is one of the most renowned screw manufacturers for motorsport: well-known racing teams from Formula 1, Nascar and Indycar series trust the excellent quality.
The threads are rolled into high-strength steel. This non-cutting process does not interrupt the fibre flow, unlike thread cutting. On the contrary, the cold forming process hardens the structure of the surface.
The benefit lies in the high safety reserves of the most heavily loaded components in the engine.
