Mobile Trailer Hitch & Coupler Repair
Stockton β€’ Lathrop β€’ Manteca

In the heavy logistics hubs of Stockton, Lathrop, and Manteca, towing double trailers is the standard. But the stress on pintle hooks, drawbars, and couplers is immense. A worn hitch or seized plunger means that trailer is dead weight in the yard. We don't just grease the fittingβ€”we weld, fabricate, and replace heavy-duty hitch components on-site. Fleet yards 100+ trailers across Northern California including Sacramento, Tracy, Modesto, Roseville, Fairfield, Dixon, Elk Grove, West Sacramento & Woodland.

FAQ: Hitch & Coupler Repair

Can you repair a coupler or do you replace it?

If the internal latch kit is broken, we can often rebuild it. If the metal housing is cracked or bent, we must replace the entire coupler for safety.

My pintle hook has "slop" in it. Is that bad?

Yes. Excessive play causes "trailer whip." We can install air-cushioned pintle hooks or replace the wear boosters to tighten up the ride.
