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

The FSR design on these JE Pistons 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.

What benefits does the accumulator groove offer?

When present, the accumulator groove helps reduce pressure from combustion gases. This can lead to less ring fluttering and an improved ring seal, resulting in more consistent power output from your engine.

Are these pistons compatible with all 350 SBC engines?

These pistons are specifically designed for 350 SBC engines with a 4.060-inch bore. It's always recommended to verify your engine's specific dimensions and requirements against the piston specifications before installation.

Product Details

Forged from 2618 aluminum, these JE Pistons are built for serious performance in your 350 SBC engine. This set includes eight pistons, each featuring a .450-inch dome and designed for a 4.060-inch bore. JE Pistons brings over 75 years of experience to the table, focusing on creating durable and high-performing components for demanding racing applications, from dirt tracks to drag strips.

The proprietary Forged Side Relief (FSR) design is a key feature here. It helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also shaves off extra weight. Depending on the specific application, these pistons may also include an accumulator groove to manage combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the cylinder walls, leading to quieter operation and longer life.

Every part of this piston set is made 100% in the USA, ensuring you're getting a well-built component designed specifically for your engine and its intended use. This attention to detail means you get optimized performance and durability, straight from the forge. Keep in mind these are not CARB approved and cannot be shipped to California.
