If you own a diesel truck, you already know that repairs can get expensive fast. But here’s what a lot of truck owners don’t realize: not every part needs to come out of a box from the dealer. Some of the best parts you can put on your truck come from a quality salvage yard and they’ll cost you a fraction of the price.
At Interstate Auto & Truck Salvage, we see all types of trucks come through every day. We’ve learned which parts hold up great when bought used and which ones you’re better off buying new. Here’s our top five list.
Transfer Cases
A transfer case from a wrecked truck with low miles is one of the best buys in the used parts world. These units are built to last, and if the truck was in a front-end collision, the drivetrain components are often completely untouched. You can save hundreds, sometimes over a thousand dollars, compared to a remanufactured unit.
Always ask for the mileage on the donor vehicle. Under 100k miles on a transfer case is a solid buy.
Turbochargers
Diesel turbos are expensive new. A used turbo from a low-mileage truck can work just as well and cost 50–70% less. The key is knowing what to look for, no excessive shaft play, no oil leaks at the inlet, and clean blades with no cracks or chips.
Have your mechanic inspect the turbo before you buy if you’re not sure what to look for. A quick inspection can save you from a bad purchase.
Transmission Assemblies
Allison transmissions, 6-speeds, and Aisin units all hold up well in the used market. A salvage transmission with documented mileage and no shifting complaints from the donor vehicle is a smart buy. Compare that to a rebuild cost and the math speaks for itself.
Doors, Hoods, and Body Panels
Body damage from an accident doesn’t mean the whole truck is worthless. Panels, doors, tailgates, and hoods from salvage trucks are often in great shape and matching the color at a salvage yard is easier than you’d think. This is especially useful for fleet owners keeping older work trucks on the road.
Axles and Differentials
Front and rear axle assemblies, differential housings, and ring and pinion sets from salvage trucks are solid used buys. These are robust components that rarely fail on their own, they usually end up at a salvage yard due to accident damage elsewhere on the vehicle.
Final Thoughts on Buying Used Parts
Buying used parts isn’t about cutting corners. It’s about being smart with your money. The right salvage yard, one that knows its inventory and is honest about mileage and condition, can be one of the best resources a truck owner has.
