Mack Trucks’ new Advantage chassis for highway tractors features lower weight, greater maneuverability, smoother ride, reduced cab noise and a lower center of gravity than the truck maker’s current offering, the company says. The Advantage chassis will be standard on all new Mack Vision and CH models beginning in mid-July 2004.
Advantage offers four rail options – 6 mm, 7 mm, 8 mm and 9.5 mm – all with increased resistance bending moment, or RBM. Weight-sensitive bulk haulers, for example, can use the 7 mm rail, which has a higher RBM than Mack’s current 8 mm. But depending upon wheelbase, the 7 mm is up to 100 pounds lighter. For customers requiring a very heavy-duty rail, the new 9.5 mm is a lighter alternative to the 6 mm with inside channel reinforcement. Foregoing the channel reinforcement helps eliminate the potential for corrosion.
The new chassis provides up to 50-degree outside wheel cuts. An Advantage-equipped vehicle with a 185-inch wheelbase could have an improvement of up to 15 feet in turning diameter, the company says. On the Mack Vision chassis, Advantage decreases the turning radius by 10 feet.
The standard front taper leaf suspension has new taper leaf springs spaced slightly apart to reduce friction. And the spring rate has been reduced to provide a softer ride, Mack says. An optional Hendrickson AIRTEK air-ride front axle-suspension combination provides a smooth ride and additional weight savings.
The Advantage chassis addresses a leading cause of driver fatigue – excessive interior noise and vibration, Mack says. The combination of a new engine support cross member and a new cab mounting system – complemented by new sound-dampening material in the cabs – reduces vibration and cuts noise levels by 3 decibels. Other Advantage features include:
- overall lower center of gravity and improved handling because of new engine mounts and the new taper leaf front suspension;
- Wider, “bowed-out” front frame section allowing for a 10 percent larger cooling system;
- MaxLite rear air suspension with outboard-mounted shocks for increased stability and a more accessible ride height adjustment;
- Color-coded lines for ease-of-service;
- Push-to-connect fittings to reduce the risk of air leaks;
- Charge air cooler piping re-routed to avoid potential damage from road debris;
- New Lo-Pro deckplate that accommodates lower fifth wheel heights and meets driver demand for a surface that is easier on the knees. The driveshaft is also covered to help keep debris from being thrown up on to the deckplate.
City-friendly exhaust brake
Pacbrake’s new PRXB modulating exhaust brake is designed for both in-city driving and steep long downhills, and its packaging allows for a traditional exhaust brake to be upgraded to a PRXB. The brake has up to one-third more retarding horsepower than a standard exhaust brake at 1500 rpm, and up to three-quarters the power of an engine brake, Pacbrake says. Constant backpressure adjusts as engine speed changes to maintain optimum retarding performance throughout the entire rpm range. Pacbrake says the PRXB is about one-quarter the weight and half the price of a typical engine brake.
The PRXB will be available later this year on a number of engines produced by Caterpillar, Chevy/GMC, Cummins, Detroit Diesel, Dodge, Ford, International and Mack.
Optional iron hubs for Peterbilt trucks and tractors have been upgraded to Low Maintenance System iron hubs, providing customers with increased warranty coverage and longer maintenance intervals, the company said.

Two-piece AC system
Tundra’s auxiliary air conditioning system for trucks features a split-system design, consisting of two major components. The condenser and cooling fan are mounted outside the sleeper to save space and isolate fan noise. A second compact unit, consisting of the compressor, evaporator, discharge blower and heating strip, is installed inside the sleeper. This small unit can easily be placed under a bunk or in the bottom of a closet or cabinet. Discharge air is ducted to one or more air grills. The two units are connected by insulated refrigerant tubes, which are precharged at the factory for easy installation. They can be integrated into the truck’s AC power system for operation on an auxiliary generator or shorepower connection when available.
The split air conditioning systems are offered in 10,000 and 14,000 BTU capacities, with a built-in 2.0- or 2.5-KW heating strip. They are designed to be installed by truck builders as original factory-installed equipment or for integration with auxiliary power units for retrofit on existing trucks.
Great Dane’s PunctureGuard Plus is now available on its Super LT refrigerated trailer and its popular SSL van trailer. The company introduced its PunctureGuard scuffband in early 2003. Now it is available throughout the interior of Great Dane van and reefer trailers.
PunctureGuard’s newest application is available as a van liner in a 0.100-inch thick panel and as a reefer liner in 0.050-inch, 0.070-inch and 0.100-inch thick panels. As a scuffband, PunctureGuard is available in 0.200 and 0.120 bondable scuff thicknesses for reefers and in 0.160 and 0.200 inch thicknesses as non-bondable scuff for dry freight vans.
The polypropylene material is impervious to moisture and will not deteriorate like wood liners, Great Dane says. Because PunctureGuard is a thermoplastic, it remains pliant over time, so impacts from loading equipment will not cause the material to set or curl away from the walls. As a thermoplastic, PunctureGuard can be reheated and reformed, which makes it easy to repair. It is installed with the same drill-screw fasteners used for plywood lining. Logistic post trailers will have fasteners installed vertically on 6-inch centers.

Long-haul drive tire
Yokohama Tire Corp.’s TY577 is built on Yokohama’s exclusive MSC (Maintenance Saving Concept) design. It is equipped with a combination of STEM-2 (Strain Energy Minimization) and MC compounding technologies. STEM-2 technology redirects normally destructive internal strain, reinforcing the casing to allow multiple retreads, while MC compounding technology generates less heat, allowing longer casing life and decreased rolling resistance.
Additionally, the TY577 possesses a Stress Wear Control Groove specifically positioned to redistribute the load on the outside rib of the tire, reducing shoulder step down wear. A closed shoulder rib means more rubber-to-the-road contact and increased mileage. The TY577 utilizes Yokohama’s optimal funnel-shaped groove technology that promotes stone ejection and reduces stone damage, increasing block rigidity for added traction, enhanced resistance against uneven wear and superior ride comfort. The TY577 also features a newly contoured bead design, allowing the tire to seat evenly against the rim for extremely high uniformity levels around the entire circumference for better tire-to-rim fit, smoother ride and long even wear.
The TY577 is available in four sizes: 295/75R22.5, 11R22.5, 285/75R24.5 and 11R24.5 – all with a 14-ply rating. The TY577 is supported by an extended warranty covering the product for five years through three retreads.

Rear obstacle warning
Grote’s Obstacle Detection System is an ultrasonic system that provides drivers with increased awareness while driving in reverse. With the Grote system, ultrasonic waves are sent out eight times within one second to detect obstacles within a 150-degree horizontal field of vision behind the vehicle. When properly installed, it can pick up objects as small as 10 inches tall. It uses a patented single-processing algorithm within the microprocessor that filters out erroneous signals to provide built-in error detection.
The system features a weather-resistant sensor unit mounted to the rear of the vehicle and a control unit, which is spliced into the vehicle’s back-up lamp wiring, engaging it to the transmission. The control unit is mounted inside the vehicle within easy view of the driver during normal backing practices. It will alert the driver when the vehicle is within approximately seven feet of an object by using a light and a volume-controlled audible beep. As the vehicle backs closer to the object and thus enters one of the two remaining detection zones, additional LEDs light up, and the beeps get faster.
Engine brake silencer
Walker’s NoiseBreaker, manufactured by Tenneco Automotive, is available in both single- and dual-exhaust class 7 and 8 applications. Walker says the product, designed to reduce engine noise and bark braking, features a patented ultra-high-flow design that outperforms conventional original equipment and aftermarket silencers in backpressure reduction and acoustical performance. The NoiseBreaker also combines durable construction with a high-efficiency design utilizing dual concentric Helmholtz tuners and fiberglass roving, the company says. Tenneco backs the NoiseBreaker with a four-year/500,000-mile warranty and a risk-free 90-day trial period.
