MIA's Description

The Wiseco 6598M9955AP is a forged piston designed for high-performance engines. It features a 99.55 mm bore and a 1.209-inch compression height. The piston is constructed from a 2618 high-strength alloy and includes a fully machined crown with precision ring grooves.

This piston also utilizes an ArmorGlide skirt coating, which provides seizure resistance, reduces friction, and contributes to quieter operation. Wiseco manufactures these pistons in the U.S. at their Mentor, Ohio facility.
