JE Pistons LS ASYM DISH/INV DM Set of 8 Pistons

JE Pistons is known for making strong, reliable forged pistons that have proven themselves on tracks all over the country. They've put over 75 years of experience into their parts, and this set of eight pistons for LS engines is no different. These aren't just off-the-shelf parts; they're engineered and machined right here in the USA using 2618 aluminum, which gives them the high tensile strength needed for demanding performance builds.

What sets these pistons apart is their specific design for the LS engine and your particular use. They feature a proprietary Forged Side Relief (FSR) forging design that helps cut down on friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the exact application, you might also find an accumulator groove, which helps manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. Plus, a skirt coating can further reduce friction and wear on the piston skirts and cylinder walls, leading to quieter operation.

This kit includes everything you need for an 8-cylinder LS engine build, with a 4.130-inch bore and a 0.927-inch pin. Keep in mind these pistons are not CARB approved and cannot be shipped to California. They are designed for high-demand performance applications where durability and optimized power are key.
