Demon Yamaha YXZ Front Long Travel Axle 3.5" 4340 (2016-2023)

Yamaha YXZ owners run out of axle strength long before they run out of nerve. This Demon long travel axle is a direct-fit replacement for the front position on the listed 2016-2023 YXZ applications, built to hold up where the stock part gives in.

Demon’s X-Treme Heavy Duty Axles are “Hell Rated” — upgraded from the Heavy Duty line to handle the harshest terrain in desert, sand, mud, rock and short course racing. The entire axle is 4340 chromoly steel, in and out: shaft, housing, cage, race and balls. Larger CV joints and shafts are paired with a proprietary dual heat treatment process and a re-engineered cage design, the internal components are micro-polished so the CVs do not heat up the way a standard joint does, and molybdenum grease lubricates the internals.

4340 chromoly is more elastic than stock material, so the shaft and its components absorb stress and keep it within themselves instead of transferring it into the differential and on through the drivetrain — that protects the rest of the driveline, not just the axle. The X-Treme line is also built to work with the major long travel suspension and lift kits, and Demon backs it with an industry-first two-year limited warranty.

Key Features

• Demon X-Treme Heavy Duty Axles are our strongest axles to date
• The success behind our products stems from thorough quality control
• This gives the axles the edge it needs for superior strength and longevity
• We re-engineered our cage design to enhance durability and use Molybdenum grease to lubricate the internal components
• The axle's inner components are micro-polished, so the CVs don't heat up like other products
• This helps preserve other components on the car

Built To Solve: Broken YXZ Front Axles From Real Sport Use

• Torn boots slinging grease in sand and whoops

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 Yamaha YXZ 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.
