What materials are these pistons made from?

These pistons are forged from 2618 aluminum. This material is selected for its high tensile strength, making it well-suited for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary feature from JE Pistons that 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 LS engines?

These pistons are designed for LS engines, but specific fitment can vary. It's important to confirm that the 4.065 inch bore size and other specifications match your particular LS engine build.

Product Details

This is a set of eight JE Pistons LS ASYM DM 6098 pistons, designed for LS engines. You get the pistons themselves, ready to be installed in your build. These are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of demand and high performance applications.

JE Pistons has been making forged pistons for over 75 years, and these are made entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design. This design helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons might also include an accumulator groove to help manage combustion gas pressure, which can improve ring seal and prevent fluttering. Some applications also come with a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

These pistons are specifically designed for each engine and its intended use, aiming for a balance of performance and durability. Keep in mind that these are not CARB approved and cannot be shipped to California. They are also subject to Prop 65 warnings.
