VERTEX Piston Kit 23870B

A piston kit is the foundation of engine reliability and performance—whether you're rebuilding after wear or upgrading for increased displacement and power. The VERTEX Piston Kit 23870B delivers the durability and precision needed for demanding applications, with forged construction, advanced surface coatings, and OEM-quality engineering. Choose the right piston type for your build: cast pistons for cost-effective reliability, forged pistons for extreme durability, high-compression variants for peak power, or big-bore options to unlock additional displacement.
