Uprated Connecting Rod Bolt and Nut Set by ARP. TC, TD, TF

Holding together the entire rotating assembly, these bolts needed superior fatigue strength, and who better to help us design a new set than the experts at ARP?

Working off of our copies of Morris Motors Ltd.'s fastener blueprints, our teams fused modern materials and old-world knowledge. The result: a bolt made out of heat-treated 8740 chrome moly steel with post-heat-treatment rolled threads for extra durability, delivering a tensile strength between 180,000 and 210,000 psi.
