About this part

Product Details

If you're building a high-performance Chevy LS3 engine for serious racing, a strong rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is designed to handle the demands of competition, including nitrous and forced induction setups. It includes a forged 4.000-inch crankshaft made from 4340 steel, which is a well-known material for its strength and durability under stress. The assembly also features a 58-tooth reluctor wheel, essential for proper engine management on LS3 applications.

The connecting rods are 6.125-inch H-beam style, also forged from 4340 steel, and come equipped with 7/16-inch ARP 8740 bolts for a solid connection. For the pistons, you get SRP Pro forged 4032 aluminum pistons with an inverted dome design, creating a -10cc volume to achieve a specific compression ratio when paired with the correct cylinder heads and deck height. These pistons are designed for plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. To ensure smooth operation and durability, the kit includes King XP rod and main bearings.

This rotating assembly is a complete package for those looking to build a robust LS3 engine. Keep in mind that this assembly is not CARB approved and cannot be shipped to California.
