What Info is Needed to Pick Out Replacement Slipper Spring for Harbor Freight Trailer

Published 08/26/2025

Question:

Hi….looking for slipper springs for the older 12” tire 40x48 haul master trailer Harbor Frieght . There must be millions of these trailers out there so I expect you know the ones I need. The trailer is away from my location but I could get measurements if you need them. Thanks, Steve Go Army!

Hey Steven, I would need you to get me the dimensions of your springs to see what you'd need as we don't have a way to look up what your trailer has. Especially since its a slipper setup which has a bit more variance.

If you can get me the length, width, and the axle capacity that would be what I would need.
