The parts that keep our drayage trucks pulling containers

Uptime is the quiet half of on-time delivery. The container can't come off the terminal if the tractor that's supposed to pull it is stuck in the shop waiting on a backordered part.

Why parts availability is a logistics problem

Drayage runs on appointments and free-time clocks. Miss a pull because a truck is down and you're not just losing a day — you might be paying demurrage on a box that couldn't move. So keeping the fleet running is part of running the freight, and that starts with getting the right part fast instead of waiting a week on a dealer.

The parts we lean on most

Container work is hard on trucks — constant stops at gates, heavy loads, tight yards. The categories that wear fastest are the ones we source quickest through our parts partner PartStop:

• Brakes & wheel ends — air brakes take a beating in stop-and-go drayage
• Suspension & steering — loaded and empty, all day
• Cooling system — idling at terminals runs temps up
• Engine & performance, fuel system — keep the diesel healthy
• Electrical & lighting — a dead lamp is a DOT stop
• Tires, wheels & hubcaps — heavy loads, tight turns

Parts for the brands we run

PartStop stocks parts for Freightliner, Kenworth, Peterbilt, Volvo, Mack, International, Western Star, Hino and Isuzu — plus the component names that actually fail on a truck: Bendix, Meritor, Wabco, Haldex, Dana, Eaton, Cummins and Fleetguard. That range is why we're not stuck cross-shopping five suppliers when a tractor needs a part today. You can reach PartStop at (253) 600-1351 or partstop.net.

Fleet parts FAQ

Why does Ad Hoc care about truck parts?

Because we're an asset-based drayage carrier — we own our fleet. A truck waiting on a part is a container that doesn't get pulled on time, so fast parts sourcing is part of keeping freight on schedule.

What parts wear out fastest on a drayage truck?

Brakes and wheel ends, suspension, cooling and tires — the stop-and-go, loaded-empty grind of container work wears them faster than long-haul miles.
