What is the compression ratio of these pistons?

These JE Pistons feature an 11:1 compression ratio. This is achieved through the piston dome design and volume, which is 2.4 cc for this specific set.

Are these pistons compatible with all Coyote 5.0 engines?

This set is designed for the Coyote 5.0 Modular engine platform. It's always recommended to verify the bore size and other specifications against your specific engine build to ensure a perfect match.

What does the 'Not CARB approved' note mean?

This means the pistons do not meet the emissions standards set by the California Air Resources Board (CARB). As a result, they cannot be legally shipped to California for use on vehicles registered in that state.

Product Details

If you're rebuilding the top end of your Coyote 5.0 Modular engine and looking for serious performance, a set of JE Pistons is a solid choice. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the strong tensile strength needed for high-demand applications. With a compression ratio of 11:1, they're designed to optimize power output for your specific engine build.

JE Pistons brings over 75 years of experience to the table, and it shows in their design. You'll find features like their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for weight savings. Depending on the specific application, these pistons may also include an accumulator groove to help control combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also get a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set includes eight pistons, each with a 3.660-inch bore and a dome volume of 2.4 cc, contributing to that 11:1 compression ratio. JE Pistons are engineered and machined 100% in the USA, ensuring you're getting a well-built component proven on tracks across the country. Please note that these pistons are not CARB approved and cannot be shipped to California.
