What is the tensile strength of these rod bolts?

These ARP HP40 rod bolts are heat-treated to achieve a tensile strength of 200,000 psi. This makes them considerably stronger than standard factory rod bolts.

What is included in this kit?

The kit contains ARP HP40 connecting rod bolts, the necessary nuts, and a packet of ARP's specialized assembly lube. This lube is essential for proper installation and to prevent fastener galling.

Why should I use ARP rod bolts instead of stock?

ARP rod bolts are made from a stronger aerospace alloy and are heat-treated for significantly higher tensile strength. This provides greater reliability, especially in engines that have been rebuilt or modified for increased performance.

Product Details

This kit includes ARP's HP40 connecting rod bolts, designed for early and late Volkswagen engines. These bolts are a popular choice when rebuilding or upgrading your engine's bottom end. They offer a stronger alternative to stock fasteners, helping to ensure the integrity of your connecting rods under increased stress.

ARP uses high-strength aerospace alloy for these bolts, which are then heat-treated to achieve a tensile strength of 200,000 psi. This makes them significantly stronger than typical OEM rod bolts. The kit comes with the necessary nuts and a packet of their specialized assembly lube, which is crucial for proper installation and to prevent galling.

When installing these, it's important to follow ARP's recommended torque-down procedure, which typically involves torquing the bolts to a specific stretch rather than just a rotational value. This ensures the connecting rod big end stays round and properly sized. Always refer to the manufacturer's instructions for the exact procedure for your application.
