Eagle Ford 351W 4.000in Crank 6.250in I-Beam Rods -26cc Inv Dome 4.040in Pistons Balanced Assembly

Built around a forged 4340 steel crankshaft with a 4.000-inch stroke, this balanced rotating assembly from Eagle is designed for serious naturally-aspirated racing applications. The 6.250-inch I-beam connecting rods are also forged from 4340 steel and feature 7/16-inch ARP 8740 bolts, ensuring they can handle the stresses of high-performance engines. This assembly is a solid choice for anyone rebuilding or upgrading a Ford 351W for the track.

The pistons included are Mahle forged 4032 aluminum with a -26cc inverted dome design, intended to work with the crankshaft and rod combination to achieve specific compression ratios. They come with plasma-moly file-fit rings, giving you the flexibility to set the correct ring gap for your build. King XP rod and main bearings are also part of this balanced assembly, providing well-built lubrication surfaces for critical rotating components. Having the assembly balanced from the factory saves you a significant step and ensures your engine's internals are properly weighted for smooth operation and longevity.

This rotating assembly is a substantial upgrade for a Ford 351W engine focused on racing performance. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder and the manufacturer's instructions for proper installation and break-in procedures to maximize the performance and lifespan of these components.
