Description

Rebuild your Outlander’s foundation with confidence using the REV6 Complete Bottom End Rebuild Kit for 2016–2025 models. This kit gives you every part needed to bring the lower end of your engine back to life while keeping power and reliability where they should be.

Each part is built to factory standards and tested for strength and accuracy. Because of this, your engine will run smoother, stay cooler, and last longer. The crankshaft, bearings, seals, and gaskets all work together to keep oil flowing and pressure sealed tight. In addition, the kit ships nationwide with a 1-year warranty. You can also upgrade to a 2-year no-fault plan for extra peace of mind.

Since REV6 has years of hands-on experience with Powersports engines and parts, you can trust the fit and finish of every component. As a result, your rebuild will go together easier and perform better once complete. Need torque specs or install help?
