Product Details

If you're rebuilding the bottom end of your small block Chrysler 318, 340, 344, or 360 engine, these ARP connecting rod bolts are a solid choice. They are a direct replacement for your stock bolts, offering a significant upgrade in strength and reliability for your engine's rotating assembly.

ARP is well-known for making strong fasteners, and these rod bolts are no exception. They are made from ARP's proprietary 8740 chrome moly steel, which is heat-treated to ensure it can handle the stresses of performance applications. This material is much stronger than the factory bolts, helping to prevent rod failure under high RPM or increased cylinder pressure. The bolts feature a unique wave-loc shank that helps center the bolt in the connecting rod, making installation a bit easier and ensuring they seat properly.

When you're putting an engine back together, especially if it's going to see anything beyond mild street use, using strong, reliable fasteners like these ARP rod bolts is a smart move. They are a small part of the overall build, but they play a critical role in keeping your engine running smoothly.
