Western Star Truck Parts - A/C, Heater & Beyond
Western Star builds trucks for the toughest environments on the planet, and keeping them running demands parts that meet that same standard. TruckAC+ started as a heavy-duty A/C specialist, and that expertise runs deep across our Western Star inventory - compressors, condensers, evaporators, heater cores, blower motors, receiver driers, expansion valves, control head assemblies, wiring harnesses, and electrical components, all stocked and ready to ship.
That foundation is expanding. Today, TruckAC+ carries a growing range of Western Star parts across multiple systems - because fleets and owner-operators shouldn't need five suppliers to keep one truck on the road. Whether you're sourcing a compressor or tracking down a component from another system entirely, we're building toward being the single source that heavy-duty operators can rely on.
Every Western Star part we sell - OEM or aftermarket - ships from our warehouse and carries full manufacturer warranty coverage. No guesswork, no delays, no gaps in support.
Western Star Truck Parts FAQs
Do you carry A/C parts for both on-highway and vocational Western Star models?
Yes. TruckAC+ stocks climate system components across Western Star's lineup, including on-highway models like the 5700XE and vocational configurations like the 4900 and 6900. If you're unsure which part fits your specific build, contact us with your make and model year and we'll confirm compatibility.
Are your Western Star compressors direct OEM replacements or aftermarket?
Both. We stock OEM compressors that match factory specifications exactly, as well as quality aftermarket alternatives that meet or exceed OEM performance standards. The choice depends on your preference and application - either way, the part ships with full manufacturer warranty coverage.
How quickly can I expect my Western Star parts to ship?
Orders placed on in-stock items ship same day from our warehouse. Western Star trucks are often running demanding schedules, so we don't hold inventory behind - what's listed is most often on our shelf and moves fast.
My Western Star heater core is leaking. Do you carry the full set of components needed for that repair?
Yes. Beyond heater cores, we stock the fittings, hoses, and related components that typically come into play during that repair. It's worth pulling the full system while the dash is apart - we can help you identify what else to order at the same time.
Are the manufacturer warranties on Western Star parts handled through TruckAC+ or directly with the manufacturer?
TruckAC+ fully supports and facilitates the warranty process with the manufacturer for all covered components. Please see our Warranty Information for more details.
Can fleet accounts order Western Star parts in bulk quantities?
Yes. Fleet and wholesale customers can contact us directly to set up a customer account for bulk or tax free ordering as permitted. We regularly supply fleets that run multiple Western Star units and need consistent parts availability across their maintenance cycle.
