Demon Polaris RZR Rear Long Travel Axle 3.5" 300M (2014-2023)

Polaris RZR 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 rear position on the listed 2014-2023 RZR 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.

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 Polaris RZR 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.
