Build Your Bottom End With Confidence And Strength

If you're rebuilding your Powerstroke or chasing higher performance, your rotating assembly is no place to cut corners. The ARP 250-6301 Rod Bolt Kit gives you the kind of strength and reliability that serious diesel engines demand. Whether you're towing heavy, tuning for more horsepower, or simply building for long-term durability, these bolts offer peace of mind where it matters most. Manufactured from 8740 chrome-moly steel and heat-treated to a tensile strength of around 200,000 psi, they’re significantly stronger than factory hardware. That means fewer worries about stretch or fatigue under extreme pressure. These bolts are trusted by professional engine builders for a reason, they're designed to hold up when things get real. If you’re building your 6.0L or 6.4L Powerstroke the right way, ARP makes sure your rods stay exactly where they belong.

Engineered To Outlast And Outperform Stock Fasteners

The ARP 250-6301 Rod Bolt Kit is designed to provide superior clamping force and fatigue resistance for 2003–2010 Ford 6.0L and 6.4L Powerstroke engines. Made from premium 8740 chrome-moly steel, these bolts undergo a multi-step heat-treatment process that brings them to a tensile strength of approximately 200,000 psi. That level of strength greatly surpasses OEM rod bolts, which are known to fail under increased power or repeated high-stress cycles. Precision machining ensures consistent sizing and optimal engagement, allowing for uniform torque application across all connecting rods. This consistency helps reduce the risk of uneven loads that can lead to rod bearing wear or cap distortion. Testing shows ARP rod bolts to be nearly five times more reliable than stock, making them ideal for performance applications or high-load conditions. Whether you're rebuilding a stock bottom end or upgrading for higher output, this kit delivers unmatched reliability and long-term durability. It’s the kind of hardware that gives builders and tuners the confidence to push their engines harder.
