About this part

Product Details

If you're building a high-performance naturally-aspirated LS3 engine for racing, a strong rotating assembly is the heart of the operation. This Pro Street rotating assembly from Eagle is built to handle the demands of the track. It starts with a forged 4340 steel crankshaft, measuring 3.622 inches, designed for a 58-tooth reluctor wheel common in LS applications.

Eagle pairs this robust crank with 6.125-inch long I-beam connecting rods, also made from forged 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress. The pistons are forged 2618 aluminum from Mahle, featuring an inverted dome design with a -12cc dish to achieve a specific compression ratio when paired with your cylinder heads. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gap precisely for your build. To complete the assembly, King XP series rod and main bearings are included, offering excellent wear resistance and performance.

This assembly is a solid foundation for a powerful LS3 engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
