About this part

Product Details

JE Pistons is known for making strong, forged racing pistons, and they've put over 75 years of experience into this LS ASYM FT 4100STRKR piston set. These aren't just generic pistons; they're built specifically for high-demand performance applications, especially for LS engines. They're engineered, forged, and machined entirely in the USA, using 2618 aluminum, which gives them the high tensile strength you need when you're pushing your engine hard, whether that's on the track or the street.

What sets these apart is the attention to detail. They feature a proprietary Forged Side Relief (FSR) design that helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps control combustion gas pressure to prevent ring flutter and keep your rings sealed for consistent power. Some applications also include a skirt coating designed to cut down on friction and wear, making your engine run quieter and last longer.

This set includes 8 pistons, each with a 4.155-inch bore and a flat-top design. They are designed for optimal performance and durability, making them a solid choice for anyone rebuilding or upgrading their LS engine for serious use. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
