Show original supplier description
With a 4.250-inch stroke and internal balance, it offers improved strength over cast iron and is recommended for street cars running on pump gas in naturally aspirated, non-competition applications. The journals are micropolished to a fine finish (typically 5 RA or better) and feature O.E. style straight oiling passages. This crankshaft is designed to accept O.E. replacement bearings and has .092" fillet radiuses for enhanced strength. It's important to note that the crankshaft must be balanced to match your specific rods and pistons before installation. Eagle Specialty Products is known for its comprehensive selection of engine components and a strong commitment to quality, utilizing state-of-the-art equipment and skilled craftsmen to produce parts suited for demanding applications. While it is an excellent alternative to an O.E. crankshaft, it is intended for street use and not for extreme performance competition.
