Wiseco Nissan RB25 DOME 6578M87 Piston Shelf Stock Kit

If you're building a serious performance Nissan RB25 engine, these forged pistons from Wiseco are a solid choice. They're made from 2618 aluminum, which is known for its strength, and are forged and machined right here in the USA. This means they can handle the kind of stress that comes with heavy or severe duty racing applications. Wiseco designed these pistons with features like precision ring grooves, anti-detonation grooves, and extra ring seal improvements to ensure they perform reliably under extreme conditions.

You'll also notice the ArmorGlide skirt coating on these pistons. This isn't just for looks; it helps reduce friction, resist seizure, and even makes the engine run a bit quieter. The fully machined crown also adds to the overall durability and performance. Plus, they come with forced pin oiling to keep the wrist pins well-lubricated, which is crucial for longevity in high-performance builds. This set includes six pistons, each with an 87.00 mm bore and a 31.50 mm compression height, ready to be installed in your RB25.

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.
