The DuraStar® was built with drivers in mind — and their businesses, too. Standard service-related features all help prevent costly breakdowns and keep you running longer.

The Diamond Logic® electrical system streamlines the process of integrating equipment into the chassis electrical system, giving you on-board diagnostics and a range of programmable features and safety interlocks.

Built completely of commercial-grade components and materials, DuraStar® boasts a nearly indestructible huck-bolted chassis and a sturdy cab that exceeds SAE rollover safety regulations.

TESTED AND PROVEN

From its best-in-class HVAC system to its three-piece, high-strength composite hood to its optimized drive train, this truck's components have all been tested — and proven.

READY FOR ANYTHING

Bolt-on front frame extensions allow for plows and other applications, and C-Channel reinforcements allow for heavy loads and severe-duty applications.


DRIVER SATISFACTION

 

YOUR WORK IS HARD.
YOUR RIDE SHOULDN'T BE.

The 82"-wide cab gives drivers and passengers room to maneuver. The ergonomic design of the seats, steering wheel and instrument panel help reduce driver fatigue.
