Dana introduced its new Spicer S172 series single drive axle for Class 7 and 8 vehicles during a press conference at the Technology & Maintenance Council annual meeting in Atlanta. According to Dana, the new axles retains the robustness and strength of the existing S170 drive axle while reducing weight by more than 60 pounds.

The axle is crafted for 4x2, 6x2, and 8x2 applications up to 25,000 pounds gross axle weight rating. It offers a broad range of gear ratios, from 3.07 to 6.14, and features a low hypoid offset with High-Power Density AdvanTek gearing to optimize efficiency. The high-strength pinion bearings allow for greater lifespan under heavy loads, improving durability and overall performance, the company says. In addition, a passive lube management system has been added that requires less lubricant overall while maintain optimum lobe flow.

"It uses a venturi-cover design to optimize the lube flow in the axle and to make better use of the available lubricant, so we require less lubricant that a standard axle," said Steve Slesinski, director of Dana's global product planning. "We coupled the venturi-cover with a patented lube meter that controls the amount of lubricant going in between the bearing system of the pinion. That helps reduce spin losses due to churning and thus improves axle efficiency."

The single drive axle can also be paired with the Dana tag axle as part of the Spicer EconoTrek tandem axle, a durable, lightweight 6x2 configuration that offers increased fuel economy, improved performance, and reduced maintenance for heavy-duty linehaul tractors. This system is up to 3% more efficient and up to 380 pounds lighter than typical 6x4 offerings.

The tandem version is more than 60 pounds lighter than existing D170 series ...Read the rest of this story

Trump trade adviser sees business exemptions for new tariffs

A top trade adviser to U.S. President Donald Trump said on Sunday a process will be in place for businesses to get exemptions from the White House plan to place steep tariffs on steel and aluminum, offering the first indication a tariff hike could be less broad than first thought. Peter Navarro, director of the White House National Trade Council, said countries will not be excluded from the tariffs because that would become a slippery slope, but there will be a mechanism for corporate exemptions in some cases. "There will be an exemption procedure for particular cases where we need to have exemptions, so that business can move forward," Navarro said on CNN's "State of the Union" program.

Cooper Tires Announces Proprietary Truck Tire Line

The Cooper Tire and Rubber Company has been designing and making tires for over 70 years. The company, which has had its RoadMaster line of truck tires on the market for the past decade, is now launching its own line of Cooper truck and bus radial tires.

Gary Schroeder, director of Cooper's global truck and bus tire business, explained during a press conference at the Technology & Maintenance Council annual meeting in Atlanta that the Cooper TBR (truck and bus radial) lineup of tires have been engineered to deliver quality and value.

“Fleets are continually faced with the pressure of lowering their operating costs, and tires are an area that can have a big impact on meeting those targets,” he noted. “Our North American team of engineers developed the Cooper brand truck tires with a focus on lowering the total cost of ownership for fleets.”

Cooper Truck Tires will be offered in three application-based series: The Pro Series for long-haul fleets, the Work Series tires for regional-haul and P&D applications, and the Severe Series for demanding mixed-service fleets.

According to Schroeder, all commerical Pro Series tires feature proprietary compounds and tread designs that provide a balance of fuel efficiency and long miles to removal. Work Series tries are designed to deliver fuel efficiency combined with scrub-resistant properties. And the Severe Series tires are built to withstand heavy scrub and cut/chip environments. All the Cooper TBR tires have a full-width, four-steel bet package to allow multiple retreads.

The new Cooper TBR tire family is SmartWay certified and backed by a 7-year, two-retread warranty, with full replacement value on the first 50% of tread life on all Pro and Work Series tires.
