Polaris Ranger 1000 Complete Engine Rebuild Kit + Upgraded Tensioner (2017–2024)

If your Ranger 1000 is knocking, losing oil pressure, or showing crank or timing wear, this complete engine rebuild kit gives you everything needed to rebuild it correctly the first time. Designed specifically for 2017–2024 Polaris Ranger 1000 models, this kit includes upgraded internal components built for durability in real-world Powersports applications.

This is not a partial refresh. This is a full bottom-end and top-end engine rebuild solution built for serious DIY mechanics and professional shops.

Why This Ranger 1000 Rebuild Kit Stands Out

• • Heavy-duty twin crankshaft for improved durability
  • Forged connecting rods for strength under load

  • Complete bearing and seal solution

Every component is precision-engineered to meet or exceed OEM specifications, ensuring proper bearing clearances, crankshaft alignment, and timing system reliability.
