Demon Can-Am Maverick X3 Rear Race Spec 300M Axle (2017-2024)

Can-Am Maverick X3 owners run out of axle strength before they run out of nerve. This Demon race spec 300m axle is a direct-fit replacement for the rear position on the listed 2017-2024 Maverick X3 applications, built to hold up where the stock part gives in.

Demon’s X-Treme Race Spec axles are redesigned and re-engineered around a 300M shaft built to flex and absorb force rather than snap under it. They are aimed squarely at constant CV breakage and drivetrain failure on machines running heavy lifts, oversized tires and long days, and they keep the same goal as the rest of the line: a race-ready axle that does not burn a hole in your pocket.

What sets 300M apart is the composition. This aircraft-grade alloy is a modified, reinforced version of the already robust 4340 chromoly, with vanadium added and a higher silicon content. Vanadium — a common element in high-speed tool steel — raises the steel’s strength substantially, and the added silicon increases strength and hardness while improving resistance to high-temperature oxidation. The result is an axle built to hold up in the harshest conditions.

Key Features

• 300M aircraft-grade alloy shaft — reinforced 4340 with vanadium and higher silicon
• Designed to flex and absorb force rather than fail under shock load
• 4340 chromoly throughout shaft, housing, cage, race and balls
• Micro-polished internals so the CV joints run cooler
• Molybdenum grease for low friction and smooth motion

Built To Solve: Broken Rear Axles On A High-Power Sport Machine

• Rear shafts twisting or snapping on hard launches and hill climbs
• Driveline shudder that shows up under throttle and not on coast
• Torn boots throwing grease across the rear suspension
• Heat build-up in the rear CVs on long, fast desert runs
• Repeat rear axle replacement once tire size and power go up

Best For: Sport Riders Who Load The Driveline

• Dune and sand riders putting power down through soft ground
• Desert and whoop riders running long miles at speed
• Owners who have already broken an OEM shaft on this chassis
• Machines running a tune, a turbo or taller tires
• Anyone who carries a spare axle and would rather not need it

Fitment

Demon lists this part for 2017–2024 Can-Am Maverick X3/X3 Max Rear Left, Rear Right Xtreme Heavy Duty Axle Race Spec 300M.

Fitment is not guaranteed on applications outside that range. Confirm your model year, trim and machine width before ordering — and if you run aftermarket suspension, confirm your kit.

FAQ

Is this one axle or a pair?

One axle, sold each. Order quantity two if you are replacing both sides.

Why do stock axles break?

Axles fail where the shaft and CV joint run out of articulation and plunge travel under load. Demon uses larger CV joints and shafts and a dual heat treated chromoly shaft to raise that limit.

What are TPEE boots?

Thermoplastic polyester elastomer. Demon uses them because they are stiffer and more fatigue, puncture and temperature resistant than a standard OEM boot — boots are where many axle failures start.

What is 300M steel?

Demon describes 300M as an aircraft-grade alloy: a modified, reinforced 4340 chromoly with vanadium and higher silicon content added for strength and high-temperature oxidation resistance.

Does this fit my machine?

Check the fitment section above against your year, model and trim. Demon lists this part only for the applications shown, and fitment is not guaranteed outside them.

What warranty does Demon offer?

See the specifications above for the warranty Demon lists on this part.

Why Demon

Demon Powersports developed this line through years of research and development, aiming at parts that outlast the stock component without a race-parts price. Their products go through testing before launch, and the heavy duty and X-Treme tiers are what they put behind their own racers.

Complete Your Can-Am Maverick X3 Build

Confirm your year, model and trim against the fitment above before ordering, and check the position line — some Demon parts are sold each and some as a set. If you are replacing a worn part, look at what wears alongside it: on a driveline that means the carrier bearing and u-joints, on the front end it means ball joints and tie rods. Replacing one worn component next to another about to fail is how people end up doing the job twice.
