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.

The weak link in a connecting rod has always been the bolt, and racers know that nobody builds a better bolt than ARP. However, it is critically important to monitor the stretch of each bolt and replace it when it has permanently elongated by .001 Inch. ARP rod bolts are superior to those from other manufacturers - especially in the area of fatigue strength.

Testing has shown ARP rod bolts to have twenty times the fatigue strength of other bolts. As such, it makes good sense to rely on ARP for optimum connecting rod service and reliability. You'll find the ARP name proudly stamped on each bolt as your assurance of quality.

L19 is a very high strength material capable of delivering a tensile strength at 260,000 psi. L19 requires special care to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion.

It must be kept well-oiled and not exposed to moisture.

Note: The grip length in undercut bolts is the distance from the head to the start of the undercut.
