The Titan 779-017 Wheel Spacer is a precision-machined component that fits onto the axle between the wheel hub and the frame or between dual wheels (where applicable). It positions the wheel correctly to prevent rubbing against the sprayer frame, fenders, or other components, ensuring smooth rolling and stable maneuverability. The spacer also helps distribute load evenly across the axle bearing.
Over time, wheel spacers can crack from impact, corrode from chemical exposure, or become lost during wheel changes. A missing or damaged spacer causes wheels to rub, leading to uneven tire wear, difficult steering, frame damage, or axle failure. Replacing a worn or missing wheel spacer with a genuine Titan 779-017 restores proper wheel alignment, protects the axle assembly, and ensures safe, easy transport on ProMark II and PowrLiner units.
