About this part

Product Details

If you're building a naturally-aspirated LS engine for racing, this balanced rotating assembly from Eagle is a solid choice for your Chevy 4.8L or 5.3L. It includes a forged 4140 crankshaft with a 4.000-inch stroke, a 58-tooth reluctor wheel for compatibility with most LS engine management systems, and 6.125-inch I-beam connecting rods made from strong 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability under stress.

The assembly also features forged 4032 DSS flat-top pistons with a -5cc dish, designed for a 3.820-inch bore. These come with plasma-moly file-fit rings, giving you the flexibility to set your own ring gap for optimal performance and sealing. King XP rod and main bearings are included, providing well-built lubrication surfaces for the crankshaft and connecting rods. This entire assembly is balanced at the factory, saving you a significant step and ensuring smooth operation right out of the box.

This rotating assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary tools and knowledge for engine assembly, or consult a professional mechanic to ensure proper installation and performance.
