About this part

Product Details

When you're rebuilding the heart of your Ford 4.6L, starting with a solid rotating assembly is key. This Manley Performance rotating assembly gives you the core components you need to build a strong engine. You get a lightweight 4340 forged steel crankshaft, 4340 forged steel H-beam connecting rods, and 2618 forged aluminum pistons, all designed to handle increased performance demands.

The crankshaft is forged from 4340 steel for strength and durability, while the H-beam connecting rods are also made from 4340 forged steel. These rods come equipped with 3/8-inch ARP 8740 cap screws, or you can opt for ARP 2000 cap screws for even more clamping force. The Platinum Series pistons are forged from 2618 aluminum, known for its strength and ability to withstand high temperatures. They come with premium chrome moly wrist pins for reliable operation. This assembly also includes high-performance piston rings and narrowed high-performance Clevite H Series rod bearings, which are crucial for proper oil clearance and bearing life in a performance application.

This assembly is intended for performance builds and is not CARB approved, meaning it cannot be shipped to California. It's important to note that this is a major engine component, and proper installation by a qualified mechanic is recommended to ensure optimal performance and longevity.
