Eagle 35640040 V8 Engine Rotating Assembly Kit

The Eagle 35640040 is an 8-cylinder engine rotating assembly kit from Eagle Specialty Products, a leading manufacturer of high-performance crankshafts, connecting rods, and complete rotating assemblies for racing and performance engines.

Eagle rotating assemblies are designed to deliver a balance of performance, reliability, and value by combining carefully matched components into a single, ready-to-install package. Each assembly is test-fitted at the Eagle facility to ensure proper component fitment before shipment.

What's Typically Included in an Eagle Rotating Assembly:

• Eagle crankshaft (cast or forged 4340 steel depending on application)
• Eagle connecting rods (I-Beam or H-Beam forged steel with ARP rod bolts)
• Matched pistons (hypereutectic or forged, depending on application)
• Piston rings (plasma-moly or file-fit)
• Rod and main bearings (King or Clevite)

Important Balancing Note: Assemblies with part numbers beginning with "B" are pre-balanced by Eagle and require no additional balancing. Assemblies without the "B" prefix must be balanced by a qualified machine shop prior to installation. Internally balanced assemblies do not include a flexplate or harmonic damper.

Eagle Specialty Products rotating assemblies are engineered for 8-cylinder applications and are built to support demanding street, street/strip, and competition use. Confirm specific stroke, bore, rod length, and piston specifications with the manufacturer or seller prior to purchase to ensure compatibility with your engine build.
