The Peterbilt 389 is the direct successor to the legendary 379 and is basically the modern torchbearer of the classic long nose look.

Compared to the 379, the 389 adds:

• Better aerodynamics.
• Modern dash & electronics.
• Advanced safety systems (collision mitigation, stability control).
• Better HVAC, insulation, and ride quality.

Why Drivers Love It:

• Keeps the long hood + external air cleaner.
• Insanely customizable (chrome, lights, stretched frames).
• Still feels like a “real truck”.

Dura-Lite supplies radiators for the Peterbilt 389, a heavy-duty long-haul truck where cooling performance really matters. Dura-Lite Peterbilt 389 radiators are designed to be direct aftermarket replacements for OEM cooling systems and are stronger and longer-lasting thanks to reinforced headers and rugged construction.
