Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 3.913in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this Pro Street rotating assembly is a prime example of their commitment to performance. If you're building a naturally-aspirated LS1 engine for racing, this assembly is designed to handle the demands of that application. It brings together all the critical rotating parts you need to get your engine project moving forward.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, providing a strong foundation for your build. It's paired with 6.125-inch I-beam connecting rods made from durable 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable performance under stress. The assembly includes forged 4032 DSS pistons with an inverted dome design, featuring a -15cc volume. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's specific needs. To ensure smooth operation and proper lubrication, King XP rod and main bearings are included, offering excellent wear resistance.

This rotating assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS1 applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's essential to verify fitment and ensure all components meet your local emissions regulations before installation.
