2005 Peterbilt 379X Conventional Sleeper Semi Truck

This 2005 Peterbilt 379X is not just another used truck—it’s a fully rebuilt, performance-focused unit designed for serious work. At the heart of it is a CAT 6NZ pre-emission engine that has been completely gone through with high-performance pistons, a new cylinder head, camshaft, turbo, and injectors. The engine has been dyno tested and properly broken in, now delivering an impressive 555 horsepower thanks to a high-performance kit, with all maintenance records available to support the build. Paired with an Eaton 18-speed transmission and upgraded drivetrain components including new differentials, this truck is built to handle demanding applications such as oilfield work or heavy hauling. It features a 270-inch wheelbase and 3.55 gear ratio, providing an ideal balance of power, efficiency, and road performance. Additional upgrades include a fresh CVIP, new brake components, ABS module, and cooling system improvements, meaning you’re stepping into a truck that has already had the major work completed. The 70-inch sleeper provides comfort for long hauls, while features like a Webasto heater, LED lighting, dual stacks, and a Herd SRT bumper add both functionality and presence. With 325,770 miles and extensive documentation available, this is a rare opportunity to own a mechanically refreshed 379X that’s ready to go straight to work.
