Eagle Chevy LS1 3.900in Crank 24 Tth Reluctor 6.125in I-Beam Rods 3.903in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you a complete package for your Chevy LS1 engine build, including a 3.900-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 3.903-inch pistons. It's designed specifically for naturally-aspirated racing applications, meaning it's built to handle the demands of high-RPM operation without forced induction.

The crankshaft is forged from high-strength steel and features a 24-tooth reluctor wheel, essential for LS1 engine management systems. The I-beam connecting rods are well-built for durability under racing stress, and the pistons are sized to match the bore and stroke for optimal compression and performance. This assembly is a solid foundation for building a powerful, naturally-aspirated LS1 engine that can withstand the rigors of the track.

When assembling this rotating group, pay close attention to balancing and clearances as per the manufacturer's specifications. This assembly is not CARB approved and cannot be shipped to California. Please consult all manufacturer documentation before installation.
