Dodge offers Class 4-5 chassis
Dodge unveiled the Ram 4500 and 5500 Chassis Cabs, expanding into the Class 4 and 5 markets from the Class 3 Ram 3500 chassis cab introduced last year. The new trucks, offering gross vehicle weight range of 14,000 to 19,500 lbs., feature a 305-hp Cummins Turbo Diesel engine with 6.7-liter displacement and 610 lb.-ft. of torque, and a six-speed automatic or manual transmission with power takeoff (PTO) capability. The truck also has the largest standard fuel tank (52 gallons) in its segment, Dodge says.

“With commercial performance, durability and capability, the 2008 Dodge Ram 4500 and 5500 Chassis Cabs offer dominant powertrain packages, a commercial-grade upfit-friendly chassis, and bold, ‘big-rig’ Ram styling,” says George Murphy, senior vice president of global brand marketing for the Chrysler Group.

Dodge also touts the largest brake rotors (390 mm) and largest caliper pistons (66 mm) in their class, as well as best-in-class first-gear launch. The trucks feature standard 34-inch frame rail spacing and a one-piece C-channel rear-frame rail fashioned from 50,000-psi steel. As with the 3500, the company emphasizes the trucks’ upfit-friendliness; all chassis components are below the frame surface, improving adaptability. Offered in dual-rear-wheel models, four cab-axle lengths (60, 84, 108 and 120 inches) are available.

The engine is compatible with biodiesel up to a 5 percent (or B5) blend. A standard diesel exhaust brake system offers extended brake life and increased driver control, Dodge says. Two-wheel-drive and four-wheel-drive models feature a recirculating ball system that provides precise response and an on-center steering feel through lower internal friction. The rear suspension on two- and four-wheel-drive models is equipped with leaf springs and includes standard two-stage springs as part of the spring design for greater load-carrying capability.

Among the safety and security features of the Dodge Ram 4500 and 5500 Chassis Cabs are an enhanced seat belt reminder system; an energy-absorbing steering column; an enhanced accident response system that turns on interior lights and unlocks doors following air bag deployment; knee bolsters to further protect occupants during frontal impacts; and a theft deterrent system that uses a transponder in the engine key to ensure authorized operation.

Isuzu’s 2008 N-Series
Isuzu Truck’s N-Series low cab forward medium-duty truck for model year 2008 will feature more cab room, more power and enhanced safety features, the truck maker says. The N-Series also meets more stringent federal and California diesel emissions requirements that took effect at the beginning of this year.

“As with other recent enhancements, the all-new N-Series was developed with direct input from those who know this vehicle best – our customers,” says Joe Totaro, executive vice president and general manager for General Motors Isuzu Commercial Truck. “It’s why we say that the 2008 N-Series was designed by our customers, for our customers.”

The greatest focus in the 2008 model enhancements was driver comfort. Features include an improved cab mounting that delivers a smoother ride and a larger cab with more side-to-side and front-to-back room, providing more seat travel and increased head, shoulder and leg room. To help with ingress and egress, the 85-degree swing-out door opening is wider, as is the self-cleaning entry step.

Other changes to improve driver convenience include:

  • A new dashboard featuring a 5-din opening for optional electronic equipment such as radios, GPS systems and rearview cameras;
  • An easy-to-remove panel at the front of the cab for easy access to the wiper motor and linkage, electrical cab connections and air intake filters, facilitating maintenance of these items;
  • New storage areas in seat backs, the dashboard and the glove box as well as overhead storage shelves and rear storage organizer;
  • Large map pockets incorporated into the new, fully trimmed door panels;
  • Standard power windows and door locks;
  • Cup holders in the center console for extra-large fountain drinks and in the dash for regular-sized cans and cups;
  • An auxiliary power outlet for a cell phone or other electronics; and
  • Door-mounted ashtrays.

While reducing emissions, the overhead cam 5.2L 4HK1-TC turbocharged, intercooled, diesel engine in the 2008 model N-Series features an increase in horsepower to 205 at 2400 rpm – up from 190 hp. Torque increases to 441 lb.-ft. at 1850, up from 387. The engine covers GVW ranges from 12,000 to 19,500 pounds and has a B10 durability rating of 310,000 miles, meaning 90 percent of the engines should reach this mileage before a major component failure, assuming that good maintenance practices have been followed.

Isuzu N-Series diesel models include the NPR, NPR HD (regular and crew cab) NQR (regular and crew cab) and NRR.

For Isuzu N-Series customers who prefer a gasoline engine, NPR and NPR HD models are available with the Vortec 6.0L V-8 engine. For 2008, the Vortec 6.0L delivers 325 horsepower – 25 more than the previous version – and 360 lb.-ft. of torque. These models are mated to the Hydra-Matic 4L80 four-speed automatic with lockup torque converter and overdrive.

Ford 2008 F-Series Super Duty
Ford launched its 2008 F-Series Super Duty work truck, the industry’s best-selling pickup in the over 8,500-pound truck segment. The 2008 product line comes in three cab styles – Regular Cab, SuperCab and Crew Cab – and two bed lengths. The new Super Duty trucks have a new 6.4-liter Power Stroke Diesel, a new look and several unique features including a

With its 2008 launch, Ford has expanded its Super Duty trucks to include the new F-450 pickup for pulling a heavier trailer while maintaining ride comfort. The F-450 incorporates a new rear leaf-spring suspension and dual rear wheels to offer a maximum payload of more than 6,000 pounds and towing capacity of more than 24,000 pounds – a 5,000-pound increase over the F-350.

The all-new 6.4-liter Power Stroke Diesel is cleaner and 10 decibels quieter than the 6.0-liter engine in 2007 models, the company says. The new engine delivers 350 horsepower at 3,000 rpm and 650 lb.-ft. of torque starting at 2,000 rpm. It uses Ford Clean Diesel Technology, which includes, among other features, a high-pressure, common rail fuel system, Piezo-electric fuel injectors and an advanced diesel particulate filter system. The engine reduces particulate output by more than 90 percent and posts emissions numbers on par with gasoline engines, according to Ford.

On the inside, the new trucks have a prominent center stack that houses most of the vehicle’s switches, integrating all functions into one easy-to-reach central area. The auxiliary switches and Trailer Brake Control system are now fully integrated into the center stack for a cleaner, user-friendly appearance. Super Duty utilizes several technologies to provide a quiet cabin, the company says. Quiet Steel, a unique composite laminated steel sheet, makes up the vehicle’s dash panel and works with extra sound padding in the dash and floor. A rear bulkhead panel and thicker side glass helps keep unwanted noise out of the cabin.

All audio systems now are MP3-capable and feature a standard auxiliary audio input. The input allows an MP3 player to play through the vehicle’s stereo system. A DVD-based navigation system with an in-dash screen is available on FX4 and Lariat SuperCabs and Crew Cabs.

The larger, more prominent grille, sharply sculpted fender flares and fender-mounted air vents are just a few of the new design features. The larger grille also helps improve cooling, which in turn improves, among other things, trailer towing capability.

The optional tailgate step is housed in the tailgate with the lower step becoming the center of the top rail of the tailgate when not in use. A grab handle folds up and out of the tailgate to provide extra support when using the step, supporting up to 300 pounds. When not in use, the grab handle fits snugly into a channel molded into the tailgate inner-liner. For added safety, the tailgate liner has an added coating, creating a nonslip walking surface.

Enhanced air dryer
Haldex says that its Multi-Treatment Cartridge Plus (MTC+) soon will be available as standard on Haldex DRYest and PURest Air Dryers. The coalescent filter on the outlet passage of the MTC+ removes 40 percent more of the fine oil and hydrocarbon particles from the air brake system than competitive air drying cartridges, according to the company; once the air has passed through the desiccant bed of the cartridge, the coalescent filter removes the oil particles remaining in the air stream.

The MTC+ – using a five-stage process to deliver the driest, cleanest air – also is designed to remove more than 99 percent of contaminants from the air brake system. This drying capacity does not impede air flow, Haldex says; by preventing oil contaminants from building up in the air system reservoir, the MTC+ ensures adequate air volume is available for air brake system components downstream of the air dryer. This reduces corrosion and freezing problems caused by inadequate air flow, according to the company.

The MTC+ cartridge’s drying capabilities also allow it to last longer, resulting in lower lifecycle cost, Haldex says. There are no hard-to-remove, spin-on cartridges where seizing can become a problem; instead, a 4-bolt slide-in and -out design is designed to allow for quick replacement of the cartridge while the air dryer is still on the vehicle. The MTC+ also is engineered for a direct fit, with no modifications necessary to DRYest and PURest Air Dryers already in operation.

Rolling tarp system
Aero Industries says its new Conestoga 2 rolling tarp system – the only system in the industry where steel wheels glide on a stainless steel track insert – features many innovations:

  • Aero’s proprietary bow shocks are designed to reduce road shock and add to the longevity of the tarp system; the standard double uplift bows reduce tarp sag to 8 inches, and the optional quad uplift bows reduce tarp sag to 3 inches, maximizing internal clearance.
  • A panelized tarp looks like it is one, smooth piece. Panelized tarps allow damaged sections to be replaced easily. The aluminum bows are hidden, providing a continuous surface for graphics.
  • The tarp fabric is formulated for the Conestoga 2 and has a urethane outer coat to provide a clean and shiny appearance. The tarp automatically seals between the track and bump rail, and an internal rubber seal minimizes air entry and stabilizes the tarp. The system eliminates the need for the cable in the bottom tarp hem. The bump rail, in addition to helping the tarp seal, also protects the tarp during loading with forklifts.
  • The rear locking mechanism allows the driver to determine and set the proper tarp tension, eliminating the need for periodic maintenance adjustments. It is operated easily from the ground, and the rear lock mechanism travels with the rear bow assembly; there are no cumbersome ratchet straps or bulky devices to remove and store. The front locking mechanism is a positive catch design, allowing the driver to simply turn a crank to draw the front bow securely to the bulkhead. It eliminates the risk of latches not locking.
