JE Pistons LS ASYM DISH/INV DM Left Single Piston

If you're building or rebuilding a Chevrolet LS Gen III or IV engine, this single inverted dome/dish piston from JE Pistons is a solid option. JE Pistons has been making forged racing pistons for over 75 years, and they build these right here in the USA using 2618 aluminum. This material gives you the strong tensile strength you need when you're pushing your engine hard, whether that's on the track or just for spirited street driving.

What sets these pistons apart is how they're designed specifically for each engine and application. This means you get optimized performance and durability tailored to your LS engine. They feature a proprietary Forged Side Relief (FSR) design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Some applications also include a skirt coating to cut down on friction and noise, and an accumulator groove to improve ring seal for consistent power delivery.

This is a single piston, designed for a 4.010 inch bore with a 1.115 inch compression distance and a 0.927 inch pin. Keep in mind that this part is not CARB approved and cannot be shipped to California.
