      Make sure you select parts designed for the type of dolly you own—motorcycle, self-loading wheel, car carrier, or standard automotive dollies.

      Axles, hubs, and bearings tend to wear out over time. Regularly replacing these ensures smoother operation and prevents costly breakdowns.
    3. Stock Hardware for Quick Repairs
      Having bolts, pins, and camlocks on hand minimizes downtime, especially for operators working in the field.
    4. Match Brand-Specific Components

    FAQ: Dolly Parts

    What types of dolly parts are available?
    We offer axles, frames, hubs, wheels, bearings, hardware, trip assemblies, and more for maintaining or repairing all major dolly types.

    Do dolly parts fit all brands?
    Not always. Collins, In The Ditch, and GoJak dollies often require brand-specific parts, so it’s important to confirm compatibility before purchasing.

    How often should dolly parts be replaced?
    It depends on usage. High-frequency towing operators may need to replace wear components like bearings and axles more often, while shops may see longer service life.

    Are OEM dolly parts better than generic replacements?
    Yes. OEM parts are designed to match the exact specifications of your dolly, ensuring safety, performance, and long-term reliability.

    Can I buy individual dolly parts or only kits?
    You can purchase both. We carry individual parts for targeted repairs as well as complete assemblies when full replacements are needed.
