Manley Nissan SR20 86.50mm 5.365in Rod 86mm Stroke 9:1 Dish Piston Set - Set of 4 Extreme Duty

This is a set of four Manley Performance Extreme Duty pistons designed for Nissan SR20 engines. You get the pistons themselves, each featuring a 9:1 compression dish. These are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings for serious strength. They also come standard with premium chrome moly wrist pins, and the pistons themselves have moly skirt coatings to help them glide smoothly against the cylinder walls.

Manley puts a lot of care into the details that make an engine perform well and last. The cam and barrel skirt profiles are carefully shaped to make good power while also being easy on your cylinder walls. They also machine the ring lands and grooves to very strict standards, which helps ensure a solid seal for the piston rings, leading to more power and better efficiency. A unique fixturing process allows them to machine the skirt and the ring grooves in the same operation, which guarantees the ring grooves are perfectly square to the skirt. This attention to detail is why professional engine builders trust Manley for demanding builds.

Because these are a performance-oriented component, it's important to note they are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your SR20 for serious performance, these pistons are a well-built option to consider.
