JE Pistons LS ASYM DISH/INV DM Right Single Piston

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into their LS engine components. This single piston is built for Chevrolet LS Gen III and IV engines, featuring an inverted dome/dish design. It's forged in the USA from 2618 aluminum, which gives it the high tensile strength needed for demanding performance applications.

This piston is designed specifically for the LS engine and its intended use, aiming for an optimal balance of durability and performance. It includes features like a proprietary Forged Side Relief (FSR) design to minimize friction and power loss, and depending on the application, it may have a skirt coating to reduce friction and wear on the cylinder walls while also quieting operation. An accumulator groove, also application-dependent, can help reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery.

This is a single piston, measuring 4.010 inches in bore diameter, with a 1.115 inch compression distance and a 0.927 inch pin. Please note that this part is not CARB approved and cannot be shipped to California.
