About this part

Product Details

These Manley Platinum Series pistons are forged from 2618 alloy, a material chosen for its exceptional strength and performance under demanding conditions. They are specifically designed for the Nissan RB26DETT engine, featuring an 86.75mm bore and a +17cc dome that contributes to a 9.0 compression ratio. This setup is built for serious engine builders and tuners looking for a well-built component that can handle significant power.

Manley's design incorporates proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on the cylinder walls. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved power output. A unique fixturing process allows Manley to machine the skirt and ring grooves in a single operation, which guarantees ultimate squareness between the ring groove and the skirt. This attention to detail means you're getting a piston that's not only strong but also precisely made for optimal engine function.

Included with these pistons are premium chrome moly wrist pins, known for their durability. For those pushing the limits, Manley offers upgrades to even stronger wrist pin alloys. This set is not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your RB26DETT and need a robust, high-performance piston, this Manley set is a solid option.
