Can-Am Maverick X3 Transmission Gear Reduction Kit, 8620 Chromoly, 10-30%

Bolt bigger tires on a Maverick X3 and the snap you used to feel off the line goes soft, because the drivetrain is now turning a much taller tire. This transmission gear reduction kit gears the X3 back down so the torque comes back, launches feel punchy again, and the clutch isn't working overtime. Pick the reduction that matches how far you've gone on tire size.

Highlights

• Restores lost torque and acceleration after a tire upgrade
• Made from 8620 chromoly steel
• Heat treated and precision ground gears for a better contact pattern
• Smooth, quiet meshing
• 10%, 20%, or 30% reduction depending on kit and model

Choosing the Right Reduction

If your tires are only a little bigger than stock, a light reduction is plenty. Run tires that are much larger and you'll want a bigger reduction to get the torque back where you expect it. The two kits work out differently on XMR models, so pick your model first:

• All other X3 models: GRK-CA-X3-020 gives a 20% reduction, and GRK-CA-X3-030 gives a 30% reduction.
• XMR models: GRK-CA-X3-020 gives a 10% reduction, and GRK-CA-X3-030 gives a 20% reduction.

The fitment section below lists exactly which years and models fall under each.

Built for Performance

These gears are made from 8620 chromoly steel for durability under heavy load. Each gear is heat treated and then ground to final shape, which improves the overall contact pattern between the teeth. Better contact means the gears mesh smoothly, carry load better, and run quieter than a rough-cut gear.

Features and Specs

• Made of 8620 chromoly steel
• Improved contact pattern for smooth, quiet operation
• 10%, 20%, or 30% reduction options
• Run larger tires with punchier acceleration
• Precision cut gears for smooth meshing

Who It's For and What Pairs Well

This kit is for X3 owners who have moved up to bigger mud or rock tires, or added a lift and heavy accessories, and want the bottom-end pull back. A tougher belt is a smart add at the same time; see Can-Am Maverick X3 clutch and transmission parts. Running big tires is hard on axles too, so check the X3 axles and CVs.

Installation

Installing a gear reduction means opening up the transmission, so it is a job for a mechanically confident owner or a shop. Confirm whether you have an XMR or another model before ordering, since the reduction you get depends on it.
