JE Pistons COYOTE 5.0 MODULAR 9.5:1 Set of 8 Pistons

Forged in the USA from 2618 aluminum, these JE Pistons are built to handle the demands of a high-performance Coyote 5.0 Modular engine. With a 9.5:1 compression ratio and a 3.660-inch bore, this set of eight pistons is designed for builders looking for serious power and durability. JE Pistons brings over 75 years of experience to the table, ensuring that each piston is engineered specifically for its application, offering a balance of strength and performance proven on tracks across the country.

This piston set features JE Pistons' proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also contributes to saving weight. Depending on the specific application, these pistons may also include an accumulator groove. This feature helps reduce pressure from combustion gases, which in turn minimizes ring fluttering and improves ring seal for more consistent power delivery. Additionally, a skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This kit includes eight pistons, each with a 3.660-inch bore, a 1.174-inch compression distance, and a 0.866-inch wrist pin. The dish volume is -8.7cc, contributing to the 9.5:1 compression ratio. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for the ultimate combination of durability and performance in their Coyote 5.0 build, these JE Pistons represent a well-built choice.
