Eagle 138754075 8-Cylinder Engine Rotating Assembly Kit

The Eagle 138754075 is a complete rotating assembly designed for 8-cylinder engines, providing builders with all the essential internal components needed for engine construction or rebuild. This comprehensive kit delivers the performance and reliability that Eagle Specialty Products is known for in the racing and performance engine market.

A complete rotating assembly includes the crankshaft, connecting rods, pistons, piston rings, and bearings—all the moving components within the engine block that convert combustion energy into rotational motion. Eagle rotating assemblies are engineered to work together as a matched set, ensuring proper balance, clearances, and compatibility right out of the box.

Eagle Specialty Products has built a reputation for producing high-strength connecting rods and crankshafts for racing engines, along with complete rotating assemblies for popular engine combinations. Their assemblies are designed to provide the ultimate reliability and strength at an affordable price for demanding applications.

Depending on the specific application and performance level, Eagle rotating assemblies may include cast steel or forged crankshafts, I-beam or H-beam connecting rods with ARP bolts, hypereutectic or forged pistons, quality piston rings, and precision bearings. The components are selected to match the intended use, whether street performance, street/strip duty, or full competition.

Professional balancing is recommended before installation to ensure smooth operation and longevity. Some Eagle assemblies come pre-balanced, while others require balancing by a qualified machine shop. Always verify specifications and fitment for your specific engine application before purchase.
