Product Details
Starting with a 4.000-inch forged 4340 crankshaft, this Eagle rotating assembly is built for serious performance, especially for racing applications that might include nitrous or forced induction. The crankshaft features a 24-tooth reluctor wheel, essential for proper engine management on many LS-based engines. It's paired with 6.125-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force.
The pistons included are forged 4032 SRP units, designed with an inverted dome measuring -10cc. This specific dome volume helps achieve a desired compression ratio when paired with the correct cylinder heads and gasket thickness. They come complete with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. To ensure smooth operation and proper oil control, the assembly includes King XP rod and main bearings, which are well-regarded for their performance in demanding conditions.
This is a comprehensive rotating assembly designed for builders looking to push the limits of their Chevy LS2 engine. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures to ensure the longevity and performance of your engine build.
