Eagle 158204090 8-Cylinder Engine Rotating Assembly Kit

The Eagle 158204090 is an 8-cylinder engine rotating assembly kit from Eagle Specialty Products, a performance engine components manufacturer that has been building high-strength rotating assemblies since 1992. Designed to serve as a comprehensive bottom-end solution for V8 engine rebuilds, this kit provides the core reciprocating components needed to complete a full engine rebuild project.

What's Included:

• Crankshaft (cast or forged, depending on configuration)
• Connecting rods with ARP rod bolts
• Pistons with rings
• Rod and main bearings

Key Features:

• Complete bottom-end kit — includes crankshaft, pistons, piston rings, connecting rods, and rod bearings for an 8-cylinder engine
• Eagle quality components — Eagle rotating assemblies are test-fitted in-house to ensure all components work together correctly
• Broad piston manufacturer sourcing — Eagle sources pistons from top manufacturers including Mahle, JE/SRP, Icon, KB, CP/Arias, and others
• ARP fasteners — connecting rods feature ARP 8740 or ARP 2000 series bolts for reliable clamping force
• King or Clevite bearings — every assembly includes quality bearings suited to the intended application

Eagle rotating assemblies are designed to simplify the engine building process by providing matched, pre-selected components in a single kit. Assembly part numbers prefixed with "B" are balanced by Eagle and require no additional balancing; unbalanced assemblies must be balanced by a qualified machine shop prior to installation. Please verify the specific stroke, bore, rod length, and balance configuration for this part number to confirm fitment and compatibility with your engine block.
