Wiseco Nissan KA24 Dished 9:1 CR 89.0 Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components for performance builds. If you're working on a 1995-1998 Nissan 240SX and need to rebuild or upgrade the engine, this Wiseco Professional Series piston set is built for serious applications. These pistons are designed to handle heavy to severe duty performance use, giving you the confidence to push your engine further.

Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine environments. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they come with forced pin oiling to ensure proper lubrication. Wiseco also applies an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. This set is designed to be a shelf stock kit, meaning it's ready to go for your build.

This kit includes a set of four pistons, each with an 89.00 mm bore and a 9:1 compression ratio. The compression height is 33.94 mm, and they use a 0.8268-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for performance builds where engine durability under extreme conditions is a priority.
