Manley Mitsubishi 4B11 86.5mm Bore 10.0:1 CR +2cc Dome Turbo Tuff Piston Set w/ Rings

Manley Performance is well-known for building strong engine components that professional builders trust. This Turbo Tuff piston set is designed for the Mitsubishi 4B11 engine, offering a significant upgrade for those looking to build a more powerful and durable engine. With a bore of 86.5mm, a compression ratio of 10.0:1, and a +2cc dome, these pistons are engineered to handle increased performance demands.

These pistons are forged from domestic 2618 alloy, a material chosen for its superior strength and ability to withstand high temperatures and pressures common in performance applications. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being gentle on your cylinder walls, reducing wear over time. Manley also pays close attention to the details, ensuring exacting standards for ring lands and grooves. This precise machining enhances ring seal, which is crucial for maximizing power output and preventing blow-by. The included wrist pins are made from premium Chrome Moly for added durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

This set includes the pistons, rings, and wrist pins necessary for installation. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Manley's installation guidelines for specific details regarding assembly and break-in procedures to ensure optimal performance and longevity of your new engine build.
