What material are these pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all 302 SBF engines?

This set is designed for a 4.030 inch bore. While intended for 302 SBF engines, it's crucial to verify that your specific engine build and bore size match the piston specifications for optimal performance and fitment.

Product Details

JE Pistons is known for making well-built forged racing pistons, drawing on over 75 years of experience. They've applied that knowledge to this set of 8 pistons for the 302 SBF engine. These aren't just generic pistons; they're engineered specifically for this engine and demanding performance applications, aiming for the best balance of durability and power.

Forged in the USA from 2618 aluminum, these pistons have the strong tensile strength needed for high-stress situations. They feature JE's 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, you might also find an accumulator groove to help control combustion gas pressure, reducing ring flutter and improving seal for consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set is designed for a 4.030 inch bore with a 1.175 inch compression distance and a -11.0 cc dish volume. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
