Why Buy Your Detroit Diesel 2-71 Crankshaft & Related Components from Diesel Pro Power

The Detroit Diesel 2-71 is one of the most compact and enduring engines in the legendary Series 71 line. Known for its reliability and simple two-cylinder design, it powered a wide range of industrial, marine, and generator applications for decades. At the heart of every 2-71 engine lies its crankshaft — a precision-balanced component responsible for converting the reciprocating motion of the pistons into smooth rotational energy. Whether you’re restoring a vintage 2-71 or maintaining one still in active service, choosing the right crankshaft and related components is essential for performance, balance, and long-term durability. Diesel Pro Power is the world’s best source for premium aftermarket 2-71 crankshafts and related components, trusted by marine and industrial professionals worldwide.
