VERTEX 23879B Cast Stroker Piston Kit

All pistons are heat treated with a T-5 hardening and tempering cycle

All piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life

Cast piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston

Forged pistons are forged from 2618 aluminum for superior strength and durability

Forged High Compression pistons improve power and torque across entire rpm range

Big Bore pistons increase engines displacement, torque, and peak horsepower

Forged Replica pistons are forged OE replacements

Replica pistons and all rings are OEM replacements

The VERTEX 23879B Cast Stroker Piston Kit is a replacement engine component set designed for builders and technicians working with compatible stroker applications. Manufactured as a cast piston kit, it provides a practical solution for refreshing or assembling an engine where the correct piston configuration, compression requirements, and internal component compatibility have been confirmed. The kit format helps keep the related piston components organized for installation and service.
Before ordering or installation, verify that VERTEX part number 23879B matches the engine application, bore specification, stroke configuration, compression ratio, connecting rod arrangement, and any other required internal measurements. Proper piston-to-wall clearance, ring
