About this part

Product Details

Starting with a 3.900-inch stroke crankshaft, this Eagle rotating assembly is built for serious LS7 engine builds. The 6.125-inch long H-beam connecting rods are forged from strong steel, designed to handle the stresses of high-performance applications, including those using nitrous or forced induction. The assembly includes 4.125-inch bore pistons with a -15cc dish, which helps achieve a specific compression ratio when paired with your LS7 cylinder heads.

This rotating assembly is a well-built package for racers and performance enthusiasts looking to rebuild or upgrade their LS7 engine. The 58-tooth reluctor wheel is standard for many LS-based engines, ensuring compatibility with your engine management system. Eagle has a reputation for producing robust components, and this assembly is no exception, offering a solid foundation for builds aiming for significant power output. It's important to note that this assembly is not CARB approved and cannot be shipped to California.

When planning your build, consider that this is a critical component for your engine's power and durability. Ensure all supporting components, such as bearings, rings, and fasteners, are selected to match the performance level of this rotating assembly. Proper balancing of the complete rotating assembly is also a crucial step for engine longevity and smooth operation at high RPMs.
