A large number of connecting rod manufacturers have chosen ARP bolts as standard equipment. They're proud to advertise their products as being equipped with ARP rod bolts. And for good reason.

However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .0005".
