Wiseco Nissan SR20 Professional Piston Set - 86.50mm Bore - 32.00mm CH

This is a set of four Wiseco Professional Series forged pistons for your Nissan SR20 engine. These pistons are built from 2618 aluminum, which is known for its improved tensile strength, making them a solid choice for demanding builds. They feature precision ring grooves, anti-detonation grooves, and additional features designed to improve ring seal, all contributing to better performance and durability under stress.

You'll also find an ArmorGlide skirt coating on these pistons. This coating helps reduce friction, makes operation quieter, and resists seizure, which is crucial when you're pushing your engine hard. The fully machined crown is designed for optimal combustion, and the forced pin oiling system ensures the wrist pins stay well-lubricated. These pistons are designed and built in the USA to handle heavy to severe duty performance applications, giving you the confidence to remove your limits.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have all the necessary supporting components and refer to the manufacturer's installation instructions for proper fitment and assembly.
