What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This alloy is chosen for its high tensile strength, which is necessary to withstand the extreme pressures and temperatures found in high-demand performance and racing engines.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that reduces skirt width and uses a shorter wrist pin. This construction helps to minimize friction and power loss while also saving weight, contributing to overall engine efficiency and performance.

Are these pistons compatible with all 350 engines?

This set is specifically designed for 350 Small Block Chevy engines with a 4.070 inch bore. It's important to verify your engine's specific bore size and compression distance requirements to ensure proper fitment.

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into this set of pistons specifically for the 350 Small Block Chevy. If you're building a high-performance engine, especially for racing applications, these pistons are built to handle the stress and deliver consistent power. They're engineered and machined right here in the USA, using a strong 2618 aluminum alloy that's well-suited for demanding use.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means they've reduced the skirt width and used a shorter wrist pin, which not only cuts down on weight but also helps minimize friction and power loss. Depending on the specific application, you might also find an accumulator groove, which helps control combustion gas pressure to keep the rings seated properly and prevent fluttering. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, leading to a quieter engine and longer life for both the piston and the cylinder. Because they're designed for each specific engine and use, you're getting optimized performance and durability.

This set includes eight pistons, each with a .450 dome and designed for a 4.070-inch bore. They use a 0.927-inch pin and have a 13.5cc volume in the dome. Keep in mind these are not CARB approved and cannot be shipped to California. If you're serious about building a powerful 350, these pistons are a solid choice from a well-known name in performance engine components.
