The Ram 3500, 4500, and 5500 Chassis Cab trucks add several fleet-friendly options for the 2015 model-year, including a maximum speed limiter to help fleet managers reduce excessive speeding, according to Ram Truck.

The 2015 Ram Chassis Cab offers the maximum speed setting on all three models equipped with the 6.4L HEMI V-8. Fleet managers can set the top speed at 60, 65, 70, or 77 mph to improve fuel efficiency and safety. The National Fire Protection Association (NFPA) requires a 77 mph limit on ambulance, fire, and other rescue vehicles.

Certain Ram 4500 and 5500 models will also gain increased GVWR for 2015. A Max Payload Package offered on the 5500 equipped with a 6.4L HEMI V-8 adds a new torque converter to the commercial-duty Aisin AS66RC automatic transmission.The package increases GVWR to 19,500 pounds on 84-, 108-, and 120-inch wheelbase models and 19,000 pounds on the 60-inch wheelbase.

The Max Payload package also increases the GCWR to 26,000 pounds and equips the truck with a 4.88:1 rear axle ratio.

Standard GVWR will increase on all 60-inch wheelbase 4500 and 5500 chassis cab trucks. Gasoline and diesel 4500 models will increase standard GVWR to 16,500 pounds and 5500 models will increase to 19,000 pounds.

Other options include ParkSense back-up sensors available for upfitter installations and Ram Work Grade vinyl seats for the interior.

The Ram 4500 and 5500 Chassis Cab models still top out with 6.4L HEMI V-8 and 6.7L Cummins diesel engine options. The V-8 produces 410 hp and 429 lb.-ft. of torque while the diesel produces 325 hp and 750 lb.-ft. of torque. Ram also offers a 5.7L HEMI V-8.

The 2015 Ram 4500 and 5500 Chassis Cab trucks carryover towing and GCWR from the 2014 model-year. The Ram 4500 offers a maximum trailer weight of 24,650 pounds and a GCWR of up to 32,500 pounds. The Ram 5500 offers a maximum trailer weight of 29,600 and a GCWR of up to 37,500 pounds.

    Anyone with a handheld tuner can set the speed limiter on just about everything made nowadays. It only took a few seconds to change the limiter on my 2013 Silverado 1500. Problem is, few people are aware that speed limiter features are built in to the ECM of just about every vehicle being made.
