Eagle Chrysler 340 3.310in Crank 6.123in I-Beam Rods -6cc Flat Top 4.070in Pistons Rotating Assembly

If you're rebuilding the heart of your Chrysler 340 for serious naturally-aspirated racing, a strong rotating assembly is where you start. This Pro Street rotating assembly from Eagle is built to handle the demands of the track, providing a solid foundation for your engine build.

At its core is a 3.310-inch forged 4340 crankshaft, known for its strength and durability under high stress. Paired with this are 6.123-inch I-beam connecting rods, which are secured with 3/8-inch ARP 8740 bolts, ensuring a reliable connection between the crank and pistons. The assembly includes hypereutectic KB pistons with a -6cc flat top design, sized at 4.070 inches, and plasma-moly file-fit rings, allowing for precise gap setting to optimize performance and sealing. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation.

This assembly is designed for performance applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all manufacturer installation guidelines before assembly to get the most out of these well-built components.
