Eagle 18201000 8-Cylinder Engine Rotating Assembly Kit

The Eagle 18201000 is a complete engine rotating assembly kit designed for 8-cylinder applications. Eagle Specialty Products rotating assemblies are test-fitted in-house before shipping to ensure all components work correctly together, giving engine builders confidence before the first bolt is turned.

Eagle rotating assembly kits are engineered to deliver a balance of performance, durability, and value. Each kit bundles the core reciprocating components needed for a performance engine build, saving builders the time and effort of sourcing individual parts from multiple vendors.

Kit Includes:

• Crankshaft (cast steel or forged 4340 steel depending on configuration)
• Connecting rods (I-Beam or H-Beam construction)
• Pistons with rings
• Rod and main bearings (King or Clevite)

Key Features:

• Components are pre-fit and test-assembled at the Eagle facility for quality assurance
• Available in balanced and unbalanced configurations — assemblies with part numbers beginning with "B" are pre-balanced by Eagle and require no additional balancing
• Unbalanced assemblies must be balanced by a qualified machine shop prior to installation
• Compatible piston options sourced from leading manufacturers including Mahle, KB, Icon, JE/SRP, and others
• ARP rod bolts for superior clamping strength and reliability
• Rings suited to the intended application included with pistons

Eagle Specialty Products is one of the largest aftermarket connecting rod manufacturers in the world, with decades of engineering experience behind every kit. The 18201000 rotating assembly is built to support demanding street, street/strip, and performance engine builds in 8-cylinder platforms.
