Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -5cc 3.898in Pistons Rotating Assembly

Starting with a 4.000-inch forged 4340 steel crankshaft, this Eagle rotating assembly is built for serious performance, especially in racing applications that might involve nitrous or forced induction. The crankshaft features a 58-tooth reluctor wheel, which is crucial for proper engine management on LS1-based engines. This assembly is designed to handle the stresses of high-output builds.

Complementing the robust crankshaft are 6.125-inch H-beam connecting rods. These rods are forged from 4340 steel and come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under extreme loads. The pistons are forged 4032 DSS flat-tops with a -5cc dish, designed to work with the crankshaft and rods to achieve a specific compression ratio. They also include plasma-moly file-fit rings, which allow for precise gap setting to optimize sealing and performance. King XP rod and main bearings are included, offering improved durability and reduced friction for the rotating assembly.

This is a comprehensive package for anyone rebuilding or significantly upgrading a Chevy LS1 engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation guidelines for proper assembly and tuning.
