Manley Chrysler Hemi 6.1L 4.080in Bore 3.579in Stroke -11.5cc Dish Platinum Series Extreme Duty

Manley Performance is well-known for building high-performance engine components, and their Platinum Series pistons are a prime example of that expertise. If you're working on a Chrysler Hemi 6.1L engine and need pistons that can handle serious power, this set is designed for you. These pistons feature a -11.5cc dish, a 4.080-inch bore, and a 3.579-inch stroke, making them a solid choice for rebuilding or upgrading your Hemi.

What sets these pistons apart is the material and the precision machining. They're forged from domestic 2618 alloy, which is chosen for its exceptional strength and ability to perform under high stress. Manley also uses proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating power. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings, leading to more efficient combustion and better power output. For added durability, these pistons come with premium Chrome Moly wrist pins, and Manley's unique machining process ensures the ring grooves are perfectly square to the skirt.

When you're building a high-performance engine, the details matter. This set includes everything you need to get started with the pistons themselves, and the quality of the forgings and machining means they're built to last. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any engine build where durability and performance are key, Manley's Platinum Series pistons are a popular choice among professional builders.
