About this part

Product Details

This is the Eagle Chevy LS7 4.125-inch crankshaft, 6.125-inch H-beam connecting rod, and -5cc piston rotating assembly. It's a complete package designed for serious LS7 engine builds, especially those intended for racing applications where reliability under extreme stress is key. This assembly is built to handle the demands of high-horsepower setups, including those using nitrous oxide or forced induction.

At its core is a forged 4340 steel crankshaft with a 4.125-inch stroke, providing the foundation for increased displacement. Paired with this are 6.125-inch H-beam connecting rods, known for their strength and ability to withstand high RPMs and significant cylinder pressures. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their robust clamping force. The pistons are forged 2618 aluminum with a -5cc dish, designed for a 4.130-inch bore, and come with plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. King XP rod and main bearings are included, offering excellent wear resistance and smooth operation under load.

This rotating assembly is a well-built option for anyone looking to build a powerful and durable LS7 engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures to ensure optimal performance and longevity.
