Eagle Chevy LS7 3.900in Crank 24 Tth Reluctor 6.125in I-Beam Rods 4.130in Pistons Rotating Assembly

If you're building a naturally-aspirated LS7 engine for racing, this Eagle Pro Street rotating assembly is a solid foundation. It bundles together the critical components that make up the heart of your engine's power generation: the crankshaft, connecting rods, and pistons. Getting these matched and balanced from a reputable source like Eagle can save you a lot of time and potential headaches during your build.

This assembly starts with a 3.900-inch stroke crankshaft, designed to work with the LS7's displacement. It's paired with 6.125-inch I-beam connecting rods, a popular choice for their strength and weight balance in performance applications. The kit includes 4.130-inch pistons, bringing the total displacement into the LS7 range. A 24-tooth reluctor wheel is also part of the package, which is essential for the engine's computer to accurately read crankshaft position. Eagle is known for well-built components, and this assembly is intended for demanding, naturally-aspirated racing use where reliability and performance are key.

When assembling an engine of this caliber, it's crucial to follow the manufacturer's specifications for balancing, clearances, and lubrication. This rotating assembly is designed for performance builds and is not CARB approved, meaning it cannot be shipped to California. Ensure you consult your build plans and any specific requirements for your racing application before ordering.
