What material are these pistons made from and why is it important?

These pistons are forged from a domestic 2618 alloy. This alloy is chosen for its superior strength and performance characteristics, making it ideal for high-output engines where durability under stress is critical.

What is the purpose of the moly skirt coating and the cam/barrel profiles?

The moly skirt coating helps reduce friction and improve durability. The cam and barrel skirt profiles are designed to generate substantial power while also minimizing wear on the cylinder walls, contributing to a longer engine life.

Are these pistons compatible with all 5.8L engines from those years?

This set is specifically designed for the 5.8L engine found in the 2013-2014 Ford Mustang Shelby GT500. It's important to confirm your specific engine configuration to ensure proper fitment, as variations can exist.

Product Details

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious engine builds in your 2013-2014 Ford Mustang Shelby GT500 with the 5.8L engine. The 2618 alloy is chosen for its exceptional strength, making it a reliable choice when you're pushing your engine hard.

Manley incorporates proven cam and barrel skirt profiles, which help generate substantial power while also being designed to be gentle on your cylinder walls. This design, combined with exacting standards for ring lands and grooves, ensures a better ring seal, translating directly into more power. The pistons also feature a moly skirt coating for improved durability and reduced friction. Each set includes tool steel wrist pins, known for their toughness, and the unique fixturing Manley uses allows for skirt turning and ring groove machining in a single operation, ensuring ultimate squareness between the ring groove and the skirt. This attention to detail is why professional engine builders trust Manley for their performance builds.

This set is for the 5.8L engine and features a 3.681-inch bore with a 1.22-inch compression distance. Please note that these pistons are not CARB approved and cannot be shipped to California.
