JE Pistons Nissan 91-98 240SX KA24DE 89.5mm Bore -4.6cc Dome Vol F Skirt Piston Kit - 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 applications. This piston kit is specifically built for the Nissan 240SX with the KA24DE engine from 1991 to 1998. These aren't just replacement parts; they're forged components designed to handle the stresses of high-demand performance builds.

Forged in the USA from 2618 aluminum, these pistons offer the high tensile strength needed for serious engine work. They feature JE Pistons' proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width to minimize friction and power loss while also saving weight. Depending on the specific application, you might find an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This kit is designed specifically for the KA24DE engine to optimize performance and durability. It comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for your engine rebuild. Please note that these pistons are not CARB approved and cannot be shipped to California.
