Eagle 628204030 Street & Strip 8-Cylinder Rotating Assembly Kit - 4.030 in. Bore

The Eagle 628204030 is a Street & Strip rotating assembly kit designed for 8-cylinder engines, built around a 4.030-inch bore. Eagle's Street & Strip rotating assemblies feature a cast crankshaft, forged 5140 steel I-Beam rods, and either hypereutectic or forged pistons. These assemblies are recommended for pump-gas street vehicles.

With an Eagle assembly, you take the guesswork out of selecting bottom-end components — every rotating assembly is test-fitted in-house to ensure everything works well together.
