What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, especially under high-temperature and high-pressure conditions common in performance engines.

What is the purpose of the skirt coating?

While not all part numbers include it, select Manley pistons feature moly skirt coatings. This coating helps to reduce friction between the piston skirt and the cylinder wall, leading to improved performance and reduced wear over time.

Are these pistons suitable for a street car or just a race car?

These pistons are built with materials and profiles that offer both strength for performance applications and reduced wear for longevity. They are a popular choice for professional engine builders and tuners, indicating they are well-suited for high-performance street or track use where durability and power are key.

About this part

Product Details

If you're rebuilding the heart of your Nissan RB26DETT engine, a solid set of pistons is where you start. These Manley pistons are built for the demands of a high-performance 2.6-liter engine, ensuring your build can handle serious power. They are designed to be a direct replacement for your stock pistons, but with a significant upgrade in strength and reliability.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still generating power. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for a good seal and maximizing the power your engine makes. These pistons also come with premium Chrome Moly wrist pins, offering excellent durability for demanding builds.

When you're putting together a performance engine, every component matters. These Manley pistons are a popular choice among professional engine builders because they offer a well-built foundation for serious power. They are machined with unique fixturing that ensures the ring grooves are perfectly square to the piston skirt, which contributes to better ring seal and overall engine performance. Keep in mind these are not CARB approved and cannot be shipped to California.
