Built around a 4.000-inch stroke crankshaft, this Eagle rotating assembly is a solid choice for anyone looking to rebuild or upgrade their Chevy LS3 engine. The 6.125-inch H-beam connecting rods are known for their strength and reliability, making them a popular pick for builds that see regular use. This assembly includes pistons with a -25cc dish, which is a key detail for achieving a specific compression ratio when paired with your chosen cylinder heads and block combination.

The crankshaft in this kit features a 58-tooth reluctor wheel, essential for proper engine management system communication in LS3 applications. Eagle has a reputation for producing well-built internal engine components, and this rotating assembly is no exception. The H-beam design of the connecting rods offers a strong balance between weight and durability, suitable for naturally aspirated or moderate forced induction setups. The included pistons are designed to fit a 4.075-inch bore, ensuring a precise fit within your LS3 block.

When undertaking an engine build of this caliber, attention to detail is paramount. This rotating assembly provides a strong foundation, but remember to consult your engine builder or service manual for specific assembly procedures, torque specifications, and recommended clearances. Proper balancing of the rotating assembly is also a critical step that should be performed by a professional machine shop before installation to ensure smooth operation and longevity.
