Manley Nissan RB26DETT 86.5mm Bore 9.0 CR +17cc Dome Extreme Duty Piston Set w/ Rings

If you're building a high-performance Nissan RB26DETT engine, this Extreme Duty Piston Set from Manley Performance is a solid choice. These pistons are designed for an 86.5mm bore and feature a 9.0:1 compression ratio with a +17cc dome, making them suitable for serious engine builds where durability and power are key. Manley uses domestic 2618 alloy forgings, which are known for their exceptional strength and ability to withstand high stress and temperatures, a critical factor for performance engines.

You'll find that Manley pays close attention to the details that matter for engine longevity and power. The pistons feature proven cam and barrel skirt profiles, designed to generate power efficiently while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, leading to improved power output and reduced blow-by. Each set also includes premium chrome moly wrist pins for added strength, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set includes the pistons and rings needed to get your RB26DETT engine rebuilt. Keep in mind that these are not CARB approved and cannot be shipped to California. For professional engine builders and tuners looking for reliable components for demanding applications, Manley pistons are a popular choice.
