Vehicle Information
Polaris Ranger Crew XP 1000 Side-by-Side (2017-2026)
The Polaris Ranger Crew XP 1000 (2017-2026) is a robust utility side-by-side vehicle, known for its versatility and capacity to transport passengers and gear. It is powered by a 999cc, 4-Stroke Twin Cylinder DOHC ProStar engine, delivering reliable power for both work and recreation. This model has undergone several significant evolutions. In 2018, a complete redesign introduced a new chassis and an 80 HP engine. From 2019, horsepower increased to 82 HP, alongside durability improvements including a more rigid one-piece chassis and a heavy-duty clutch. The 2025 and 2026 model years brought a major upgrade with a Gen 2 transmission, refined electronic power steering, enhanced durability, a redesigned front end, and 29-inch Pro Armor X Terrain tires starting in 2026. Trims such as the Premium and NorthStar editions have been offered throughout this period. Q : How can I ensure this part fits my Ranger Crew XP 1000?
