Description

If you’re ready to bring your Can-Am Maverick 1000 X3 engine back to full strength, this complete rebuild kit from REV6 has you covered. Designed for 2017–2023 models, it replaces every major internal component—from pistons and crankshaft to bearings and seals—so you can restore compression, oil pressure, and power output in one rebuild.

Each component is precision-machined to meet or exceed OEM standards for reliability and fit. The crankshaft and connecting rods deliver smooth rotation, while the upgraded gaskets and seals prevent leaks and keep oil where it belongs. In short, this kit helps your Maverick run cooler, stronger, and longer—mile after mile.

REV6 technicians inspect every part before shipping to ensure accuracy and quality. We also provide nationwide shipping to keep your project moving. With our 1-year warranty (and optional 2-year no-fault coverage), you’ll have confidence every time you turn the key.
