JE Pistons Nissan 91-98 240SX KA24DE 89.0mm Bore Std. Size -4 Dome Vol F Skirt Pistons - Set of 4

JE Pistons has been a leader in forged racing pistons for over 75 years, known for applying their experience to a wide range of engines. This piston set is specifically crafted for the Nissan 240SX with the KA24DE engine, covering models from 1991 to 1998. These pistons are designed to handle high-demand performance applications, offering a solid combination of durability and power for your engine build.

Forged in the USA from 2618 aluminum, these pistons offer the high tensile strength needed for demanding use. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width and a shorter wrist pin to minimize friction and power loss while saving weight. Depending on the specific application, you might find an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes everything you need to get your engine rebuilt: four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. They are designed specifically for the KA24DE engine, with a bore size of 89.0mm and a standard size. Please note that these pistons are not CARB approved and cannot be shipped to California.
