About this part

Product Details

If you're building a serious performance LS2 engine, especially one intended for racing, nitrous, or forced induction, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is built to handle the demands of high-horsepower applications. It starts with a 4.000-inch forged 4340 steel crankshaft featuring a long snout for better accessory drive support and a 58-tooth reluctor wheel for LS2 engine management.

Complementing the crankshaft are 6.125-inch H-beam connecting rods. These rods are well-built for strength and are secured with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in performance builds. The assembly includes Arias forged 2618 aluminum pistons, which are flat-top with a -4.5cc dish and sized at 4.030 inches. These pistons are paired with plasma-moly file-fit piston rings, allowing for precise ring gap adjustment to optimize performance and sealing for your specific build. King XP rod and main bearings are also included, offering robust lubrication and wear resistance under extreme conditions.

This is a comprehensive rotating assembly designed for builders who need a solid foundation for their LS2 engine. Please note that this assembly is not CARB approved and cannot be shipped to California. It's essential to consult your engine builder or refer to manufacturer instructions for proper installation and tuning to ensure optimal performance and longevity.
