Wiseco Nissan QR25DE 89.50 mm Bore 32.00 mm CH 1.80 CC Piston Set

What you get in this set are four forged pistons for your Nissan QR25DE engine, ready for a serious build. These aren't your average pistons; they're made from 2618 aluminum, which gives them improved tensile strength compared to other aluminum alloys. This means they can handle the extra stress and heat that comes with heavy or severe duty racing applications.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features that help improve ring seal. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation, which is a nice bonus when you're pushing an engine hard. The fully machined crown is also designed for performance, and the forced pin oiling helps keep the wrist pins lubricated under extreme conditions.

If you're building a performance engine for racing or heavy use, these pistons are designed to be a strong foundation. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll want to check the manufacturer's instructions for any specific installation requirements or recommended pairings for your build.
