Wiseco 95-98 Nissan 240SX KA24 4V Dished 9:1 CR 90.50MM Piston Shelf Stock Kit

Starting with a 2618 aluminum forging, these Wiseco pistons are built for serious performance in your 1995-1998 Nissan 240SX with the KA24DE engine. This set is specifically sized at 90.50mm bore with a dished crown that results in a 9:1 compression ratio, making it a solid choice for builds that demand more than stock. The material choice here is key; 2618 aluminum offers improved tensile strength over other alloys, which is crucial when you're pushing an engine hard.

Wiseco doesn't stop at the forging. These pistons feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring better combustion efficiency and durability under stress. The crown is fully machined for accuracy, and they even include forced pin oiling to keep the wrist pin lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a nice touch for a performance part that's also meant to last through heavy or severe duty applications.

This kit includes a set of four pistons, ready for your engine build. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
