Exmark or Toro zero-turn mower owners (like Lazer Z, Advantage, Z Master, Professional Series models), if your steering feels loose or shaky, these steering dampers (stabilizers) are likely the fix. This listing is for a pack of TWO upgraded dampers. The key upgrade is a dual-seal design with an extra external dust shield. This helps keep dirt and grout out of the internal seal, which is what usually causes them to fail prematurely. They're direct replacements for part numbers like 116-0027 and 109-9820. Replacing worn dampers will restore smooth, precise steering control and reduce feedback through the handles. Always confirm the fit for your specific mower model and year. A common maintenance item that makes mowing much more comfortable.
