About this part

Product Details

If you're building a high-performance Chevrolet LS engine, you need connecting rods that can handle the stress. Manley's Pro-Series I-Beam Connecting Rods are built for just that. These aren't your average rods; they're designed for serious builds where reliability and strength are paramount. They are a crucial link between your pistons and crankshaft, and getting them right is key to a healthy, powerful engine.

Manley offers these Pro-Series rods in your choice of two very strong materials: forged 4340 vacuum degassed steel alloy or the even stronger 300M vacuum degassed steel alloy. Both are chosen for their ability to withstand extreme forces and temperatures found in performance engines. Some of these rods even carry NHRA Legal certification, making them a solid choice for drag racing applications in Stock and Super Stock classes. You can also select from different weight options – Tour Lites, Lightweights, Standard, and Heavy Weights – to perfectly match your specific engine build and performance goals.

When you're putting together an LS engine that needs to perform, using well-built components like these Manley connecting rods is essential. They are a significant investment in the longevity and capability of your build. Make sure to consult your engine builder or a trusted professional to select the exact material and weight that best suits your application.
