What makes these pistons 'Extreme Duty'?

The 'Extreme Duty' designation comes from the use of strong 2618 alloy forgings and the precise machining of ring lands and grooves. These features allow the pistons to handle higher cylinder pressures and temperatures common in performance applications.

What is the compression ratio and bore size for this piston set?

This set is designed for a 3.662-inch bore and achieves a 10.0:1 compression ratio with its -0.5cc dome piston design.

Are these pistons suitable for a stock engine rebuild?

While these pistons are well-built, their design and materials are optimized for performance builds that often involve modifications. For a standard stock rebuild, you might consider a different piston set unless you plan on significant performance upgrades.

About this part

Product Details

If you're building a high-performance Ford 3.5L EcoBoost engine, you need pistons that can handle the stress. This set from Manley Performance is built for just that, using their signature Platinum Series construction. These aren't just any pistons; they're designed to be a strong foundation for serious engine builds, whether you're aiming for more power or just want the peace of mind that comes with well-built components.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to withstand high temperatures and pressures. They also feature proven cam and barrel skirt profiles, which help generate power while being easier on your cylinder walls. The ring lands and grooves are machined to strict standards, ensuring a better seal for your piston rings, which translates directly to more power and efficiency. For added durability, these pistons come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance.

This set is designed for a 3.662-inch bore and a 10.0:1 compression ratio, with a -0.5cc dome. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're serious about your EcoBoost build, these pistons are a popular choice among professional engine builders for their reliability and performance.
