The heavy-duty truck battle continues, with Ram announcing increased capacities for its 4500 and 5500 models. The 2012 Ram 4500 and 5500 medium-duty (Class 4 and 5) Chassis Cab commercial trucks will be available with an optional 30,000-pound gross combined weight rating (GCWR), an increase from 26,000 pounds.

The new Ram 4500/5500 Chassis Cab GCWR upgrade is part of an optional "Max Tow" package, and is available on both regular and crew cab models and in 4x2 and 4x4 configurations. Max Tow is available on Ram Chassis Cab trucks equipped with the optional, commercial-grade Aisin six-speed automatic transmission and 4.88 rear-axle ratio. Ram 4500 and 5500 Chassis Cab trucks come equipped with the commercial-spec 6.7-liter Cummins Turbo Diesel inline-six engine with 305 horsepower and 610 lb.-ft.

The 2012 Ram Chassis Cab with Max Tow will reach dealerships in the third quarter of 2011. Max Tow pricing will be announced closer to launch.
