Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in H-Beam -15cc 4.000in Pistons Rotating Assembly

Eagle has built a solid reputation for making tough engine components, and this rotating assembly is a prime example of that commitment, especially for Chevy LS1 engines. If you're building a performance LS1 for racing, whether it's naturally aspirated, uses nitrous, or is boosted, this assembly is designed to handle the extra stress. It's a complete package that gives you the core strength needed for serious power.

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 this are 6.125-inch H-beam connecting rods, which are well-known for their robust design and ability to withstand significant forces. These rods come equipped with 7/16-inch ARP 8740 bolts, a name trusted for reliable fasteners in high-performance applications. The pistons are forged 4032 aluminum with an inverted dome design, featuring a -15cc volume to help achieve your desired compression ratio, and they come with plasma-moly file-fit rings. To top it off, the assembly includes King XP rod and main bearings, offering excellent performance and wear resistance for your build.

This rotating assembly is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive setup for anyone looking to build a high-horsepower LS1 engine that can hold up to the demands of racing.
