Freightliner Trucks announced six severe-duty vocational product options, including the Allison 4700 Rugged Duty Series (RDS) automatic transmission, LifeGuard RollTek seats, improved routing and clipping, LED headlights in the M2 106 and M2 112, Bendix Tire Pressure Monitoring, and the 122SD auto hauler package.

All three vocational trucks featured in the Freightliner Trucks booth at the North American Commercial Vehicle (NACV) show are equipped with Detroit engines.

Freightliner launched its severe-duty product line in 2011, and has since expanded the line with product enhancements and additional options such as the Allison 4700 RDS Automatic Transmission. Available for the Freightliner 114SD, the Allison 4700 RDS provides heavy vocational operators with improved start ability, two reverse gears, enhanced PTO options, and the durability required for severe applications. The Freightliner 122SD is also available with the Allison 4700 RDS.

The LifeGuard RollTek Seats side-impact airbags inflate in the event of a rollover. The seat belt tightens and the air-suspension seats compress to the lowest position to provide additional protection to the driver.

Freightliner’s vocational product line has been updated with new standoff brackets and optimized routing and clipping of chassis electrical and plumbing harnesses to provide simpler installation and long-term durability. The body and equipment mounting is also simplified with more consistent routing paths.

Freightliner M2 106 and M2 112 trucks can be equipped with modular LED headlights.

Bendix Tire Pressure Monitoring System is available for Freightliner’s vocational product line for improved tire wear, fuel economy, and overall vehicle performance.

The Freightliner 122SD is available with a low profile auto hauler package. The package, made in collaboration with Fontaine Modification Inc., lowers the laden roof height to approximately 100-inches, for auto hauler applications that require a sleeper berth.

Vocational trucks on display in Freightliner’s NACV booth will include a Detroit DD5-powered M2 106 upfitted with a Valew service body and electric over hydraulic PTO, a Detroit DD8-powered M2 106 crew cab upfitted with a heavy spec Miller Industries rollback car and equipment carrier, and a Detroit DD13-powered 114SD set forward axle upfitted with a TBEI/OX aluminum dump body.
