Eagle 637904065 8-Cylinder Rotating Assembly Kit

The Eagle 637904065 is a complete rotating assembly designed for 8-cylinder engine applications. Eagle Specialty Products manufactures high-strength connecting rods and crankshafts for performance and racing engines, providing excellent value for street, strip, and competition builds.

Typical Rotating Assembly Components:

• Cast steel or forged crankshaft with enhanced fillet radiuses for improved strength
• Forged steel connecting rods (I-Beam or H-Beam design)
• High-quality pistons matched to specific bore and compression requirements
• Piston rings with standard or file-fit gaps
• Rod and main bearings
• All necessary hardware for complete installation

Eagle rotating assemblies are engineered to deliver reliable performance for engines producing under 500 horsepower in street and street/strip applications, or higher power levels when equipped with forged components for competition use. Professional balancing by a qualified machine shop is recommended unless the assembly is pre-balanced (part numbers beginning with "B").
