About this part

Product Details

Starting with a 3.900-inch stroke forged crankshaft, this Eagle Pro Street rotating assembly is built for serious performance in Chevy LS7 engines. It’s designed for naturally-aspirated racing applications where reliability and strength are paramount. The 4.130-inch bore pistons are paired with robust 6.125-inch I-beam connecting rods, creating a well-balanced package ready to handle the demands of the track.

Eagle has put together a solid assembly here, using quality components that work together seamlessly. The crankshaft is forged for maximum durability, and the I-beam rods offer a strong yet relatively lightweight option for high-RPM use. This assembly is a critical step in rebuilding or upgrading your LS7's bottom end, aiming for improved power and longevity under racing conditions. It comes with a 58-tooth reluctor wheel, which is important for proper engine management system communication.

When you're building an engine for racing, especially a powerful LS7, the rotating assembly is the heart of it all. This Eagle Pro Street kit gives you a complete, balanced rotating assembly from a well-known name in performance engine components. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
