Eagle has put together this assembly with serious competition in mind. The forged 4340 steel crankshaft is a solid foundation, and the center counterweight design helps manage rotational forces. The H-beam rods are a popular choice for their robust construction, and using ARP L19 bolts means you have some of the strongest fasteners available for connecting rods. The Mahle pistons are forged from 2618 aluminum, a material chosen for its ability to withstand high temperatures and pressures, and the 43cc dome is designed to achieve specific compression ratios. The plasma-moly file-fit rings allow for custom gapping, which is essential for optimizing performance and sealing in a high-stress environment. King XP bearings are known for their enhanced performance and durability, making them a good match for this heavy-duty application.
