Wiseco Nissan KA24 Dished 10.5:1 CR 89.0 Piston Shelf Stock Kit

When you're rebuilding the engine in your 1995-1998 Nissan 240SX, especially for demanding builds, this Wiseco forged piston kit is what you'll want. You get a full set of four pistons, complete with premium rings and wrist pins, all designed to handle serious performance applications. These pistons are made from 2618 aluminum, which is known for its strength, and are forged and machined right here in the USA.

Wiseco has packed a lot of smart features into these pistons. The crown is fully machined, and they include precision ring grooves, anti-detonation grooves, and other features to help seal the rings better. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizing, which is crucial when you're pushing your engine hard. The design also includes forced pin oiling to keep the wrist pins well-lubricated.

This kit is built for heavy to severe duty performance builds, aiming to remove limits for serious racers and builders. Keep in mind that 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 procedures.
