Vertex Pistons 15-19 ACE 570/15-19 ACE 570 HD Wrist Pin - 56.500mm Length

This is a Vertex Pistons wrist pin, measuring 56.500mm in length, designed for specific Polaris Ranger and Sportsman models. It's a crucial component that connects the piston to the connecting rod, allowing the piston to pivot as it moves up and down in the cylinder. For your 2014 Polaris Ranger 570 EFI, ensuring this part is in good condition is key to a healthy engine.

Vertex Pistons uses a fully case-hardened process for these wrist pins, which includes a nitride coating. This coating helps create a hard surface that resists wear and prevents galling, meaning it's less likely to seize or damage the piston or connecting rod under stress. The nitride process is notable because it achieves this surface hardness without the risk of distortion that can sometimes come with quenching, ensuring a more stable part.
