Eagle Chevy LS 4.8/5.3 4.000in Crank 24 Tth Rlctor 6.125in H-Beam 3.820in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly is a well-built package designed for serious LS engine builds, especially those looking to handle significant power increases from forced induction or nitrous oxide. What you get in this kit is a complete rotating assembly ready to be installed into your Chevy LS 4.8 or 5.3 engine block. It includes a 4.000-inch forged 4340 crankshaft, which is a strong foundation for high-horsepower applications. You also receive 6.125-inch H-beam connecting rods, known for their robust design, secured with 7/16-inch ARP 8740 bolts. The pistons are forged 4032 DSS units with an inverted dome design, measuring 3.820 inches in diameter and featuring a -15cc dish. This assembly comes complete with plasma-moly file-fit piston rings and King XP rod and main bearings for smooth operation.

The 4.000-inch stroke crankshaft is a key component, offering a longer stroke than stock for increased displacement and potential torque. The 24-tooth reluctor wheel is specifically for LS engines that use this type of sensor. H-beam connecting rods are a popular choice for their strength-to-weight ratio, making them suitable for engines that will be pushed hard. The forged 4032 pistons are designed for durability and performance, with the inverted dome helping to manage compression ratios, especially when used with aftermarket cylinder heads. The inclusion of ARP bolts means you're getting reliable hardware for critical connections. Plasma-moly file-fit rings allow for precise gapping to match your specific engine build and intended use, whether it's for racing or a high-performance street application.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be legally shipped to California. It's important to ensure your engine build plans align with these specifications, especially if you are in a state with strict emissions regulations. The King XP bearings are designed for demanding applications, offering improved durability and performance over standard bearings. When installing this assembly, proper balancing by a professional machine shop is highly recommended to ensure optimal engine life and performance, especially given the competition-focused nature of these components.
