Eagle Chevy LS3 4.000in Crank 24 Tth Reluctor 6.125in I-Beam Rods 4.005in Pistons Rotating Assembly

When you're building a naturally-aspirated LS3 engine for racing, the rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly gives you the core components you need to get started. You'll receive a 4.000-inch forged 4140 crankshaft, designed for strength and durability under demanding conditions. It's set up with a 24-tooth reluctor wheel, which is standard for many LS applications.

Paired with the crankshaft are 6.125-inch I-beam connecting rods made from strong 4340 steel. These rods come equipped with 7/16-inch ARP 8740 bolts, known for their reliability in high-stress environments. The assembly also includes forged 4032 DSS flat-top pistons with a -5cc dish, sized at 4.005 inches. These pistons are designed to work with the included plasma-moly file-fit piston rings, allowing for precise gap setting during installation. For the main and rod bearings, Eagle has included King XP bearings, which offer improved performance and durability for racing applications.

This is a well-built rotating assembly intended for serious racing use where a naturally-aspirated setup is preferred. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures, as these components are typically balanced as a set.
