If your Yamaha YXZ 1000R sees aggressive trail riding, desert miles, or upgraded suspension components, the rear axle is not a place to compromise. The Cognito Motorsports Demon Powersports Heavy Duty OE Replacement Rear Axle Assembly is engineered to deliver strength, reliability, and smooth power transfer far beyond stock limitations—without sacrificing OEM fitment.
At the core of this axle is a 4340 chromoly cage, chosen for its exceptional resistance to shock loads and torsional stress. Compared to factory axles, this heavy-duty design features a 15–20% increase in shaft diameter and 10–15% larger CV joints, giving you added confidence when running larger tires, higher traction setups, or spirited driving styles. Wider articulation angles allow the suspension to cycle more freely, reducing bind and stress during full droop or compression.
Durability extends beyond the metal components. High-quality TPEE boots are packed with high-load molybdenum grease, helping maintain lubrication under extreme heat and movement while resisting cracking and tearing in harsh environments. Precision CNC machining ensures consistent tolerances, smooth rotation, and dependable performance mile after mile.
Designed as a direct OEM replacement, this rear axle installs easily with no modifications required, making it an ideal upgrade for riders who want added strength without complex installation. It’s fully compatible with 2016–2021 Yamaha YXZ 1000R models, including SE, SS, and SS XT-R trims, and is backed by a 12-month manufacturer limited warranty.
Whether you’re reinforcing your drivetrain for tougher terrain or replacing a worn factory axle with something stronger, this Cognito Motorsports rear axle delivers the durability and performance serious YXZ owners demand. Upgrade with confidence and keep your machine pushing forward when conditions get rough.
