Eagle Chevy LS7 4.000in Long Snout Crank 58 Tth Reluctor 6.125in H-Beam 4.155in Pistons Rot Assembly

This Eagle Competition Rotating Assembly gives you a complete set of the core rotating components for your Chevy LS7 engine build. Inside this package, you'll find a 4.000-inch forged 4340 steel crankshaft with a long snout, designed to handle the demands of high-performance applications. It also includes 6.125-inch H-beam connecting rods, which are well-built for strength and durability, paired with 7/16-inch ARP 8740 bolts for secure rod cap attachment. The assembly is rounded out with 4.155-inch flat-top pistons made from forged 2618 aluminum, featuring a -4.6cc dish and plasma-moly file-fit rings for a precise seal.

This rotating assembly is specifically put together for serious racing use, including setups that utilize nitrous oxide or forced induction like turbochargers and superchargers. The 4340 forged steel crank and H-beam rods are chosen for their robust construction, capable of withstanding the increased cylinder pressures and stresses these power adders can create. The pistons are designed for a flat-top configuration, which is common for naturally aspirated or boosted builds where compression ratio tuning is critical. King XP rod and main bearings are included to ensure smooth operation and proper oil clearance for the crankshaft and connecting rods.

When building a high-output LS7, having a strong rotating assembly is fundamental. This Eagle kit provides a solid foundation, but remember that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications, especially when dealing with critical components like ARP bolts and bearing clearances.
