Vertex Pistons Vertex Piston Kit

Description

The Vertex Piston Kit offers high-quality replacement pistons for both 2-stroke and 4-stroke engines. The 2-stroke pistons are gravity-cast from aluminum alloy with 18% silicone content, ensuring a lightweight yet strong design. The 4-stroke pistons are forged from 2618 aluminum for superior strength and durability. For performance enhancements, the high-compression 4-stroke pistons increase power and torque across the entire RPM range, while big-bore pistons boost engine displacement, torque, and peak horsepower. All pistons undergo a T-5 heat treatment process for added strength and durability. The piston skirts feature a molybdenum disulfide (MoS2) coating, reducing break-in time and improving longevity. Each kit includes a piston, rings, wrist pin, and circlips. Standard and replica pistons serve as direct OEM replacements. Two-stroke replacement rings are sold individually, while four-stroke piston rings are sold as a set.
