Wiseco Mitsubishi EVO 10 4B11-T 2008+ -4.5cc Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components for performance applications. If you're building or rebuilding the 4B11T engine in your 2008, 2010-2014 Mitsubishi Lancer for serious racing or heavy-duty use, their Professional Series forged pistons are a solid choice. These pistons are designed from the ground up to handle the kind of stress that comes with demanding performance builds.

Each piston is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for durability under high loads. You'll find precision ring grooves, anti-detonation grooves, and other features to help improve ring seal and overall combustion efficiency. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these are built for severe duty performance.

This kit includes a set of four pistons, each with an 87.00 mm bore and a 33.25 mm compression height. The pin diameter is 0.9055 inches. 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.
