When you push your Yamaha YXZ 1000R beyond stock suspension limits, your driveline needs to be just as capable. The Cognito Motorsports Demon Powersports Xtreme Duty Rear Axle Assembly is engineered specifically for long travel suspension setups, delivering the strength and reliability required for aggressive off-road use.
Built from 4340 chromoly steel, the CV joints, axle shaft, and internal components are designed to withstand high torque loads, hard landings, and extended high-speed abuse. Dual heat-treated components add another layer of durability, helping prevent premature wear under extreme conditions. The double offset joint (DOJ) design reduces heat buildup during sustained desert riding, keeping performance consistent when temperatures climb.
With swing angles up to 45 degrees, this rear axle maintains smooth power delivery throughout the full range of long travel suspension movement. Precision CNC machining ensures tight tolerances for proper fitment, while high-quality lithium-based molybdenum grease with a high drop point keeps internal components protected during demanding rides.
This axle assembly is purpose-built for riders running upgraded suspension systems who demand confidence in harsh terrain, whether you’re racing, trail riding, or exploring open desert. Backed by a 24-month manufacturer limited warranty, it delivers peace of mind along with serious performance.
Designed to fit 2016–2021 Yamaha YXZ 1000R models, including SE, SS, SS SE, and SS XT-R trims, this long travel rear axle is a critical upgrade for anyone looking to maximize suspension performance without sacrificing reliability. If you’re building your YXZ to handle more travel and more abuse, this axle belongs in your setup.
