Parts Support Across the United States
Western Truck & Trailer supplies trailer parts to fleets and owner-operators across the United States including:
Parts can be ordered through our locations and shipped anywhere in the continental US.
Parts, Yard by Yard
Where a part physically lives depends on the branch. Here's the honest layout so you're not driving to the wrong yard:
Salt Lake City, UT (HQ): Full parts counter. Brakes, suspension, hydraulics, electrical, decking, and hardware on the shelf, plus the deep bench for special orders. Walk in, or call and we'll pull it.
North Las Vegas, NV: Common wear parts on hand, with anything else pulled from Salt Lake and shipped down — usually a day or two. Our Vegas service bay installs what you order.
Belgrade, MT and Atlanta, TX: Sales yards. You don't lose parts support here — you order by phone and we ship to your shop or the job site, continental US. Same parts team, same catalog, freight instead of a counter.
One parts team runs all four. Call the branch closest to you and you'll reach someone who knows the difference between a Ranco belly-dump gate cylinder and a SmithCo side-dump ram — not a call center.
What we actually stock
Six systems cover most of what puts a trailer down:
Brakes
Shoes, drums, hubs, S-cams, complete brake kits.
Suspension
Axles, spring and air-ride components, bushings, hangers.
Hydraulics
Cylinders, pumps, valves, hoses for dump and detachable-neck systems.
Electrical & lighting
Harnesses, LED and sealed lighting, wiring, connectors.
Decking
Apitong (keruing) and hardwood deck boards, milled to trailer thickness; single boards or full sets. See trailer decking.
Hardware
Mud flaps, mounts, D-rings, fittings, fasteners.
OEM from the lines we sell and service — Ranco, SmithCo, XL Specialized, Dorsey, Manac, Trail King — plus aftermarket when you want the cost-effective route. Tell us the trailer make and, if you have it, the part number; if you don't, a photo and a description gets our team to the right SKU.
