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.

“Great to work with ordered parts over the phone had them shipped directly to my shop”
Western Truck & Trailer supplies trailer parts to fleets and owner-operators across the United States, including Utah, Idaho, Arizona, California, Colorado, Wyoming, Montana, Texas, Oklahoma, Louisiana, North Dakota and South Dakota. Parts can be ordered through our locations and shipped anywhere in the continental US.
Parts by brand
We are the dealer for these lines, which is why our parts desk knows the difference between a Ranco belly-dump gate cylinder and a SmithCo side-dump ram. There is no catalogue to browse. Tell us the trailer and the part, on the form above or over the phone, and we source it and ship it.
- Ranco
- Belly dump and end dump parts: gate cylinders, hinges, windrow gates, Versa hydraulic controls, hopper sheets and tarp systems. Ranco is the line our dump inventory is built on. Ranco trailers we carry.
- SmithCo
- Side dump parts across the SX line, SX1 through SX7: tub rams and cylinders, tub pivots, Ridewell air-ride components, tarp motors and bows. Authorized dealer since 2011. SmithCo side dumps we carry.
- Dragon
- Vacuum trailer, crude transport, frac tank and roll-off parts: valves, hose pans, pumps, liners and gaskets. Dragon owns Ranco and Vantage, so a Vantage-badged end dump is the same parts desk. Dragon trailers we carry.
- Manac / CPS
- CPS belly dump and hopper parts: gate doors and slide locks, air cylinders and Versa valves, landing gear, and Manac flatbed decking, rub rails and winches. Manac and CPS trailers we carry.
Not on this list? We source parts for most commercial trailer brands whether or not the trailer came from us, including dry van, flatbed and pneumatic equipment. Shipping is nationwide, continental US.
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.
