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

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is essential for handling the extreme pressures and temperatures found in high-performance and racing engines.

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

The FSR design helps to minimize friction and power loss. It achieves this by reducing the piston skirt width and using a shorter wrist pin, which also contributes to saving weight in the engine.

Are any special tools or components needed for installation?

Installation of performance pistons typically requires specific tools and knowledge, including piston ring compressors and proper torque wrenches. It is recommended to consult the manufacturer's installation instructions or a qualified mechanic for proper fitment and assembly.

Product Details

If you're building a high-performance LS engine, getting the right pistons is crucial for durability and power. This set of eight JE Pistons LS ASYM DM 4100STRKR pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for demanding performance applications where reliability is key.

JE Pistons has over 75 years of experience in creating forged pistons, and these are made 100% in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for weight savings. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and maintaining consistent power. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise.

This set is designed specifically for LS engines with a 4.070-inch bore, a 1.065-inch compression distance, and a 0.927-inch pin. They are a dome-style piston with a -1.1cc volume. Please note that these pistons are not CARB approved and cannot be shipped to California.
