Manley Chevy LS 402 4.00in Stroke 4.005in Bore -18cc Rotating Assembly

If you're building a high-performance Chevy LS engine, this Manley rotating assembly is a solid foundation. It's designed for a 4.000-inch stroke and a 4.005-inch bore, giving you a 402 cubic inch displacement when combined with the appropriate block. This assembly includes all the key components you need to get your engine's bottom end built, saving you time and ensuring compatibility between parts.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle the stresses of a performance engine. Paired with it are 4340 forged steel H-beam connecting rods, known for their robust design. These rods come equipped with 7/16-inch ARP 8740 cap screws, or you can opt for ARP 2000 screws for even more clamping force under extreme conditions. The pistons are 2618 forged aluminum Platinum Series, a material selected for its durability and heat resistance. They come with premium chrome moly wrist pins for reliable operation. Topping off the package are high-performance piston rings and high-performance Clevite 'H' Series rod bearings (narrowed) and 'P' Series main bearings, all chosen to work together for optimal lubrication and reduced friction.

This assembly is a significant step up from stock components and is intended for serious engine builds. Please note that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Manley's detailed specifications to ensure this rotating assembly meets the specific requirements of your project.
