Manley Nissan RB26DETT 87.25mm Bore 9.0 CR +20cc Dome Extreme Duty Piston Set w/ Rings

This is a set of Manley Performance Extreme Duty pistons for your Nissan RB26DETT engine. You get six pistons, each with a +20cc dome designed to achieve a 9.0:1 compression ratio with an 87.25mm bore. They also come with the necessary rings and tool steel wrist pins to get them installed. These pistons are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their strength and performance under demanding conditions.

Manley puts a lot of thought into how these pistons interact with your engine. They feature proven cam and barrel skirt profiles that help generate power while being easy on your cylinder walls. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings and maximizing power output. This attention to detail extends to their unique fixturing process, which allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the skirt, contributing to better sealing and overall engine health.

These pistons are a solid choice for serious engine builds where durability and performance are key. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
