Diesel Design

Fuel Tank

The MB Chassis comes with a 60-, 80- or 90-gallon rectangular steel fuel tank mounted between the rails for increased safety and reduced fuel stops.

Lowered Engine Position

A lowered engine position provides a flat floor in the cockpit area, enabling drivers to safely move from cockpit to passenger area without having to step over a “doghouse.”

Viscous Fan Clutch

The MB's viscous fan clutch only activates when triggered by engine temperature, which means you get where you are going faster. It also reduces load on the engine, provides more available horsepower and increases fuel economy – all with less engine noise.

Engine and Exhaust Brakes
