JE Pistons 302/351 SBF DOME Set of 8 Pistons

If you're building a high-performance 302 or 351 Windsor small-block Ford engine, getting the right pistons is crucial for durability and power. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for demanding performance applications where stock cast pistons just won't cut it. They are designed specifically for these engines, ensuring optimized performance and longevity whether you're hitting the drag strip or the track.

JE Pistons brings over 75 years of experience to the table with these components, and they're forged and machined right here in the USA. You'll find features like their proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Some applications also feature a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set includes eight pistons, each with a 4.125-inch bore, a 1.280-inch compression distance, and a 0.927-inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build where reliability and performance are paramount, these JE Pistons are a solid choice.
