Wiseco Nissan KA24 Dished 9:1 CR 89.5 Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components for performance applications. This piston set is built for the Nissan KA24 engine, specifically for the 1995-1998 240SX. These aren't your average pistons; they're designed for serious builders who need parts that can handle heavy use and severe duty race conditions. If you're rebuilding the top end of your KA24 and want a solid foundation, these pistons are a great place to start.

Forged from 2618 aluminum right here in the USA, these pistons are built for improved tensile strength. The machining on the crown is fully done, and they feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and makes for quieter operation. This set is designed to withstand the demands of performance builds where reliability is key.

This kit includes four pistons, each with an 89.50 mm bore and a dished crown that results in a 9:1 compression ratio. The kit also includes premium rings to ensure a good seal. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
