Product Details

If you're building a high-performance GM 6.6L Duramax diesel, especially one that will see heavy use or significant power increases, you need connecting rods that can handle the stress. These Carrillo connecting rods are built for just that purpose, designed to be a strong upgrade over the factory components for LB7, LLY, LBZ, and LMM engine applications.

They feature a 6.620-inch length and are designed to work with 7/16-inch S7 bolts, which are known for their strength and reliability in demanding applications. The material and construction are chosen to withstand the high cylinder pressures and combustion forces common in modified diesel engines. This means you can push your Duramax harder, whether it's for towing, competition, or just a more powerful daily driver, with greater confidence in your engine's internal strength.

This set includes eight connecting rods, enough for a complete engine rebuild. When undertaking an engine build of this caliber, it's crucial to ensure all components are properly balanced and installed according to manufacturer specifications. These rods are a solid foundation for a powerful and durable Duramax engine.
