About this part

Product Details

Manley Performance is well-known for making strong engine components, and their Pro-Series I-Beam connecting rods are a prime example of that dedication. If you're building a high-performance Chevrolet Small Block engine, these rods are designed to handle the demands of serious power. They are 6.000 inches long, a common length for many small block applications, and are forged from 4340 vacuum degassed steel alloy, which is a well-built material chosen for its strength and ability to withstand high stress.

These aren't just any connecting rods; they are part of Manley's Pro-Series line, meaning they've been crafted with meticulous attention to detail. The 4340 steel construction offers a solid foundation for your engine's rotating assembly, providing improved durability under high RPMs and increased cylinder pressures. While this specific part number uses 4340 steel, Manley also offers other Pro-Series rods in 300M steel for even more extreme applications. Some rods in this series are even NHRA legal for Stock and Super Stock racing, which speaks to their robust design and adherence to strict standards.

You have options with Manley's Pro-Series rods, as they come in various weights like Tour Lites, Lightweights, Standard, and Heavy Weights, allowing you to fine-tune your engine build. This set is for the 6.000-inch length, a critical measurement for proper piston and crankshaft geometry. When you're aiming for maximum performance and reliability in your Chevrolet Small Block, choosing well-built connecting rods like these from Manley is a smart move.
