Manley 08+ Mitsubishi 4B11T 86mm STD -11cc Dome 9.0:1 CR Turbo Tuff Series Piston Set w/ Rings

This Manley Turbo Tuff Series piston set includes four forged pistons, rings, and wrist pins, ready to be installed in your 2008 and newer Mitsubishi 4B11T engine. These pistons are built for demanding performance applications, offering a 9.0:1 compression ratio with an -11cc dome, making them a solid choice for boosted setups where reliability and power are key.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle high cylinder pressures. The pistons feature proven cam and barrel skirt profiles designed to reduce friction and wear on your cylinder walls while still generating substantial power. You'll also find exacting standards applied to the ring lands and grooves, which helps ensure a better seal for more efficient combustion. The included wrist pins are made from premium Chrome Moly for added durability, supporting the robust nature of these Turbo Tuff series components.

Manley's manufacturing process includes unique fixturing that allows for skirt turning and ring groove machining in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, contributing to optimal ring seal and overall engine performance. If you're rebuilding or upgrading your 4B11T engine for serious performance, these pistons are a well-built option that professional engine builders trust.
