What material are these pistons made from and why is it important?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to perform reliably under the high temperatures and pressures found in demanding engine builds.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize power output while minimizing friction and wear against the cylinder walls. This helps ensure both performance and longevity for your engine.

Are these pistons compatible with all RB26DETT engines?

These pistons are designed for the Nissan RB26DETT engine with a bore size of 87.25mm. It's important to verify your specific engine's bore and clearance requirements before installation, as they are not CARB approved and cannot be shipped to California.

Product Details

If you're rebuilding the heart of your Nissan RB26DETT engine, a solid set of pistons is crucial for handling increased power and ensuring long-term reliability. These Manley Performance pistons are built for that exact purpose, designed to handle the demands of serious engine builds.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. They feature proven cam and barrel skirt profiles that help generate power efficiently while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to strict standards, which is key for achieving a good seal and maximizing the power your engine makes. Each set also includes premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.
