ARP Connecting Rod Bolt Kit

The ARP connecting rod bolt kit line gives engine builders a dependable replacement or upgrade for factory rod bolts and cap screws. ARP designs these fasteners for performance street, racing, and heavy-duty use, where stock hardware can stretch, loosen, or fail under high RPM and high cylinder pressure.

Key Features:

• Made from premium alloy steels. Depending on the series, these include high-strength chrome moly and ARP2000 or other proprietary alloys.
• Rolled threads, produced after heat treatment, improve fatigue strength and thread accuracy.
• Precision machining and tight quality control give consistent clamp load and repeatable torque.
• Each fastener is made in the USA and is inspected and batch-traceable.
• Fasteners are supplied with the specified assembly lube so they can be torqued to the correct preload.

Rod bolts hold the connecting rod cap to the rod, so they must resist the repeated stretching and compressing of each engine cycle. ARP rod bolts help maintain bearing bore roundness and stable rod geometry, which supports engine durability and power. Each part number in this line is made for a specific engine application. Follow the torque specifications and installation instructions that come with the kit.
