Eagle Chevy 4.8/5.3 LS 3.900in Crank 24 Tth Relctr 6.125in I-Beam 3.780in Pistons Rotating Assembly

If you're building a naturally-aspirated LS engine for racing, a solid rotating assembly is the heart of your build. This Eagle Pro Street rotating assembly is designed to handle the demands of that kind of performance. It's a well-built package that gives you the core components needed to get your engine's bottom end sorted out.

This assembly features a 3.900-inch stroke crankshaft, which is a common choice for increasing displacement and torque in 4.8L and 5.3L LS engines. Paired with the crankshaft are 6.125-inch I-beam connecting rods. These rods are a strong choice for naturally-aspirated applications, offering a good balance of strength and weight. The assembly also includes 3.780-inch pistons, which are sized to work with the crank and rod combination to achieve the desired displacement. The 24-tooth reluctor wheel is standard for many LS applications, ensuring compatibility with your engine's computer system.

When you're putting together a performance engine, having a matched rotating assembly like this one simplifies the process. It ensures that your crankshaft, connecting rods, and pistons are all designed to work together harmoniously. This is crucial for engine balance, longevity, and performance, especially when you're pushing the limits in a racing environment. Remember that this assembly is not CARB approved and cannot be shipped to California.
