Eagle LS3 Pro Street Balanced Rotating Assembly

This is the Eagle LS3 Pro Street Balanced Rotating Assembly, a well-built package designed for naturally-aspirated racing applications. If you're rebuilding the heart of your Chevy LS3 engine for performance, this assembly gives you the core components you need to get started. It includes a forged 4140 crankshaft, strong 4340 I-beam connecting rods with ARP 8740 bolts, and forged Mahle pistons with an inverted dome design. This assembly is balanced at the factory, saving you a significant step in the engine building process.

The crankshaft features a 4.000-inch stroke and a 58-tooth reluctor wheel, common for many LS applications. The 6.125-inch connecting rods are made from durable 4340 forged steel and come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under stress. The included Mahle pistons are forged from 2618 aluminum and feature a -20cc inverted dome, designed to work with specific compression ratios. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's bore and intended use. King XP rod and main bearings are also included, offering robust performance for demanding conditions.

This assembly is balanced by Eagle, which is a critical step for smooth engine operation and longevity, especially in performance builds. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's a solid foundation for a high-performance naturally-aspirated LS3 engine build.
