Eagle Chevy LS 4.8/5.3 4.000in Crank 58 Tth Reluctor 6.125in H-Beam 3.800in Piston Rotating Assembly

This Eagle Competition Rotating Assembly gives you a complete set of core engine components for your Chevy LS 4.8 or 5.3 build. Inside this package, you'll find a 4.000-inch forged 4340 crankshaft, a 58-tooth reluctor wheel, 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, Mahle 0cc dome forged pistons measuring 3.800 inches, plasma-moly file-fit piston rings, and King XP rod and main bearings. This assembly is designed to be a strong foundation for high-performance LS engines.

The forged 4340 steel crankshaft is built to handle significant stress, making it suitable for demanding applications like racing, including those using nitrous or forced induction. The H-beam connecting rods are also forged and come with robust ARP bolts, ensuring they can withstand the increased cylinder pressures and forces associated with performance builds. The Mahle pistons are forged from 4032 aluminum, known for its strength and durability, and feature a 0cc dome design which is often used to achieve specific compression ratios when paired with appropriate cylinder heads. The included plasma-moly file-fit rings allow for precise gap setting to optimize performance and sealing in your engine build.

This rotating assembly comes with King XP series bearings, which are well-regarded for their performance and durability in high-stress environments. Having all these critical components in one matched set simplifies the engine building process, ensuring proper clearances and compatibility between the crankshaft, rods, pistons, and bearings. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
