Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -29cc 3.905in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this competition rotating assembly for Chevy LS1 engines is a prime example of their focus on performance. If you're building an LS1 for serious racing, especially with nitrous or forced induction, this assembly is designed to handle the extra stress. It’s a complete package that gives you the core rotating parts you need to get your engine project underway.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under high loads. Paired with it are 6.125-inch H-beam connecting rods, which are also forged for added toughness. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-stress applications. The pistons are forged 4032 DSS units with an inverted dome design, featuring a -29cc volume, and they measure 3.905 inches in diameter. This assembly also includes plasma-moly file-fit rings, allowing for precise gap setting to match your specific build. For smooth operation and reliable lubrication, King XP rod and main bearings are included.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a well-built set of components that forms the foundation for a powerful LS1 engine build.
