Western Star Parts
Aftermarket parts for Western Star trucks — the severe-service 4900 and the newer 5700/49X. Logging, oilfield and heavy-haul duty is hard on cooling, wheel-end and body parts; we stock direct-replacement components with OEM cross-reference numbers for the trucks that work hardest.
