Eagle Chrysler 426 Hemi 3.750in Stroke H-Beam 6.860in Pistons 4.310in Bore Rotating Assembly

This Eagle Competition Rotating Assembly starts with a forged 4340 steel crankshaft featuring a 3.750-inch stroke and an 8-bolt rear flange, designed to handle the demands of high-performance racing, including nitrous and forced induction applications. The robust construction is key to maintaining consistent power delivery under extreme conditions.

Paired with the crankshaft are 4340 H-beam connecting rods, measuring 6.860 inches in length. These rods are secured with 7/16-inch ARP 8740 rod bolts, known for their strength and reliability in high-stress environments. The assembly includes forged 2618 Diamond pistons with a 112cc dome volume, designed for a 4.310-inch bore. These pistons are fitted with 1/16", 1/16", and 3/16" plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing.

Completing this well-built rotating assembly are King XP main and rod bearings. These bearings are engineered for enhanced durability and reduced friction, crucial for longevity in racing engines. This comprehensive package is ideal for builders looking for a solid foundation for a powerful Chrysler 426 Hemi race engine.
