    Heavy Duty Ball Joint — stud
    What Makes Them "Heavy-Duty"?

    Demon Heavy-Duty Ball Joints are built from high-grade, heat-treated 4340 chromoly steel, giving them immense tensile strength and resistance to bending or snapping. Unlike stock joints, the stud doesn't narrow, making the entire unit stronger. This heavy-duty design ensures your suspension can handle aggressive riding, heavy tires, mud, rocks, and high-speed trails without failure, providing unmatched reliability and peace of mind for every ride.

    Heavy Duty Ball Joint — complete ball joint
    2X the Strength of OEM

    Stock ball joints are designed to be cost-effective and provide a comfortable ride for average use, but for riders who push their machines, whether mudding, rock crawling, high-speed trail riding, or running heavy tires, OEM components quickly become a weak link. They wear out faster from dirt, water, and grit, can bend or break under extreme stress, and often develop looseness or “play” that leads to poor handling, vague steering, and uneven tire wear. The solution is Demon Heavy-Duty Ball Joints, engineered to be twice as strong as OEM and far more durable and reliable. Made entirely from dual heat-treated 4340 chromoly steel with zinc plating for maximum longevity, they are a direct-replacement upgrade built to withstand aggressive riding.

    Heavy Duty Ball Joint — grease fitting
    On-Demand Flush System

    Unlike OEM “sealed-for-life” joints that fail when grease breaks down, Demon HD Ball Joints come equipped with a Grease Zerk fitting for quick, easy maintenance. Pump in fresh, high-quality grease whenever needed to maintain a constant protective film inside the joint. This simple maintenance dramatically extends the life of the ball joint, keeps it performing at peak levels, and saves you from costly and frequent replacements.

    Heavy Duty Ball Joint — threaded cap
    Serviceable Threaded Cap Design

    Demon HD Ball Joints feature a unique threaded cap design that lets you adjust for wear and eliminate vertical play. As joints naturally develop slack, simply remove the pin, rotate the cap, and reinstall to restore tight, like-new tolerances. Maintains precise steering, eliminate wobble, and ensure safe handling without the hassle or cost of full replacement. This design gives your joints a second life, keeping you riding longer.

    Fitment: 2016–2024 Yamaha YXZ and Wolverine models. Fits the Upper or Lower position — one part covers either. See the Fitment tab for the full model list.
