Peterbilt 389 market position
The 389 is a long-hood conventional offered in highway and heavy-spec configurations. Wheelbase, sleeper, axle and powertrain choices have a large effect on intended use and operating characteristics.
Powertrain considerations
Available engines, transmissions and emissions equipment vary by model year. Confirm component serials, ratings and service history, especially when a truck has been modified or repurposed.
Common configurations
The 389 is commonly used for traditional-styled highway, owner-operator and heavy-spec work. Exact equipment changes by model year, market and original order.
- Day-cab and sleeper variants
- Wide wheelbase and axle configuration range
- Powertrain choices vary substantially by year and build
Buying a used 389
Inspect hood alignment and mounts, frame and crossmembers, steering, suspension, fifth wheel, sleeper structure, wiring modifications and emissions history. Price should reflect condition and specification, not appearance alone.
Models buyers also compare
A Kenworth W900 is a common traditional-conventional comparison; aerodynamic models may offer a different balance for dedicated highway work.
