The Stemco Trifecta Pre-Adjusted Hub Assembly wheel end system, developed in partnership with Webb Wheel Products, provides a quick and easy installation to ensure the hub is installed correctly. The Trifecta features the Discover XR (extreme runtime) wheel seal with GlideLock technology. The seal glides on and is self-locking, reducing installation force by 50 percent, according to the company, with no prelube required. The combination of the Discover XR wheel seal, Webb Wheel’s hub and the Defender composite hub cap provide exceptional contamination and corrosion resistance. The Trifecta assembly also features STEMCO’s Zip-Torq fully unitized axle spindle nut, increasing simplicity and safety for end users. There are no additional clips, keepers, snap rings or screws to install. The self-ratcheting locking feature prevents inadvertent back-offs. Installation of the new hub assembly requires no bearing adjustment, ensuring the hub is installed correctly, quickly and easily.
