Dolly Parts Shopping Guide

  1. Identify the Right Dolly Type
    Make sure you select parts designed for the type of dolly you own—motorcycle, self-loading wheel, car carrier, or standard automotive dollies.
  2. Replace Critical Wear Components
    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
    Collins, GoJak, and In The Ditch dollies each use brand-specific parts for best performance. Be sure to match replacements to your equipment.
  5. Inspect Regularly
    Routine checks help identify small issues before they become big problems. For more insights, check out our blog: Dolly Inspection Tips.

Frequently Asked Questions About 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.
