Polaris ACE Piston Kit - Vertex Pistons - Cast Replica - `17-`19. These cast-replica Vertex pistons are made for 2017–2019 Polaris ACE 500 models and provide a precise, OEM-style replacement designed to restore proper compression and reduce blow-by.

The kit is engineered for an exact fit in A, B or C bore sizes, giving you options to match your existing cylinder condition without guesswork. Each piston is heat treated with a T-5 hardening and tempering cycle and finished with a molybdenum disulphide (MoS2) skirt coating to promote faster break-in and improved piston life. The kit includes everything needed for installation so you can rebuild quickly and reliably.
