Eagle Ford 351W 3.850in Crank 5.956in I-Beam Rods 4.060in Pistons 157 Tooth FP Balanced Assembly

If you're building a Ford 351 Windsor engine for street performance or strip duty, a balanced rotating assembly is a critical starting point. This assembly from Eagle includes a 3.850-inch stroke crankshaft, 5.956-inch I-beam connecting rods, and 4.060-inch pistons, all precision-balanced at the factory. Getting the balance right from the start saves a lot of machine shop time and ensures your engine runs smoother and lasts longer.

Eagle is known for well-built engine components, and this assembly is no exception. The I-beam connecting rods are strong and reliable for demanding use, while the crankshaft is forged for durability. The included pistons are sized for a 4.060-inch bore, common for many 351W builds looking to increase displacement. This assembly comes factory balanced, meaning the crankshaft, rods, pistons, rings, and bearings are all weighted and matched to minimize vibration and stress on your engine's main bearings and seals. This is especially important when you're pushing an engine beyond stock power levels.

This assembly is designed for a 157-tooth flywheel, which is standard for many manual transmission applications. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you check all manufacturer specifications and local regulations before installation.
