Manley 13-14 Ford Mustang Shelby GT500 5.8L 3.681in Bore 1.22in CD Coated Pistons - Set of 8

Built with domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds in your 2013-2014 Ford Mustang Shelby GT500 with the 5.8L engine. The 3.681-inch bore size and 1.22-inch compression distance are specific to this application, ensuring a proper fit for your engine rebuild. Manley's commitment to precision means exacting standards for ring lands and grooves, which directly translates to better ring seal and more power from your engine.

You'll find that these pistons feature proven cam and barrel skirt profiles. This design choice helps generate substantial power while also being gentle on your cylinder walls, contributing to longer engine life. The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in one operation. This ensures ultimate squareness between the piston skirt and the ring grooves, a critical detail for optimal performance and reliability in high-output engines. Each set includes tool steel wrist pins for added durability, and these particular pistons come with a Moly skirt coating for improved wear resistance.

If you're rebuilding the top end of your 5.8L Shelby GT500, these pistons are a solid option. They are built to handle the demands of performance tuning and professional engine builders. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
