Manley 08+ Mitsubishi 4B11T 86.5mm (+.5mm) -11cc Dome 9.0:1 CR Turbo Tuff Series Piston Set w/ Rings

Built from domestic 2618 alloy forgings, these Manley Turbo Tuff series pistons are made for serious performance in your 2008 and later Mitsubishi 4B11T engine. They feature an 86.5mm bore size, which is a 0.5mm overbore from stock, and an -11cc dome dish that helps achieve a 9.0:1 compression ratio. This setup is designed to handle the demands of boosted applications, offering a solid foundation for engine builds aiming for more power and durability.

Manley's attention to detail is evident in the cam and barrel skirt profiles, which are shaped to generate power efficiently while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion and power output. These pistons also come with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures the ring grooves are perfectly square to the skirt, which is critical for proper ring function and sealing under high stress.

This set includes the pistons and rings needed to get your engine rebuild underway. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
