Complete Bottom End Rebuild Kit with Engine Cases for Polaris Ranger 1000 (2017–2018)

If your Ranger 1000 bottom end is worn or damaged, this complete rebuild kit gives you a full solution. Instead of trying to reuse questionable cases or mix parts, this setup replaces the entire lower assembly. As a result, your engine gets a solid foundation built to handle load and long-term use.

What This Kit Includes

• OEM crank case
• HD twin crankshaft
• Crankshaft main bearings
• Connecting rod bearings
• Balance shaft bearings
• Complete gasket & seal kit
• Timing chain
• Oil pump chain
• (2) Forged connecting rods

Built for a True Bottom-End Reset

This kit goes beyond a standard refresh. Because it includes new engine cases, it eliminates issues caused by worn or damaged housings. In turn, bearing alignment improves and internal tolerances stay where they should. That difference matters when you’re rebuilding for reliability, not just getting by.

Heavy-Duty Components Where It Counts

The HD twin crankshaft and forged rods handle more stress than stock components. At the same time, new bearings and chains support smooth rotation and proper timing. Because everything works together, the engine holds up better under load and maintains consistent performance.

Why This Kit Stands Out

Most bottom-end kits reuse engine cases. However, this setup replaces them completely. That approach removes guesswork and gives your rebuild a clean starting point. As a result, you avoid hidden wear that can shorten engine life.

Warranty & Support

All REV6 parts include a 1-year warranty, so you can install with confidence. If you need help before ordering, visit the contact page or review details in the warranty policy.
