About this part

Product Details

If you're rebuilding the heart of your Nissan RB26DETT engine, Manley's Extreme Duty Piston Set is a solid choice for serious performance. These pistons are specifically made for the RB26DETT 2.6L engine, with a bore size of 86.5mm and a 9:1 compression ratio, featuring a +20cc dome to help achieve your power goals.

Manley uses their signature 2618 alloy forgings, which are known for being strong and reliable under high stress. They've also incorporated proven cam and barrel skirt profiles designed to generate power efficiently while being kind to 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, ultimately translating to more power. Plus, Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance.

This set includes premium chrome moly wrist pins for added durability, and comes with rings. Keep in mind these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a robust and powerful RB26DETT build, these pistons are a well-built option that professional engine builders trust.
