Eagle rotating assemblies can take a lot of worry out of your engine building project. Eagle's heavy-duty rotating assemblies consist of name-brand quality components for a wide range of engines at an affordable price. Perfect for the most extreme competition engines, including exotic fuels, heavy nitrous, and high boost, Eagle's HD rotating assemblies are equipped with Eagle's forged 4340 center-counterweighted crank (when available), forged H-Beam rods with ARP 2000 or L19 bolt upgrade and purpose-built heavy duty pistons. The pistons used in Eagle's heavy-duty assemblies are built for high boost levels or bucket-loads of nitrous. Every part is top-of-the-line and ready to support whatever you want to throw at it. Most all assemblies are available balanced or unbalanced if you'd rather your machine shop balance it. Along with crank, rods, pistons, every assembly includes bearings from either King or Clevite and rings suited to the intended application. Externally balanced assemblies balanced by Eagle will also include a harmonic damper and flexplate (or flywheel for some Fords) from Pioneer. Order the model designed for fitment on your year/make vehicle and engine application.
