WARRENVILLE, Ill. — International has added a new air bag suspension system to its 9000-series sleeper cabs which promises to deliver a smoother ride and better vehicle control for drivers.
The company says it has relocated the cab suspension system to provide improved driver comfort and vehicle stability. It will also allow team drivers to get a better sleep while their driving partner is behind the wheel, the company says, as it will reduce cab roll and sway.
Enhancements to the new suspension system include: locating the air bags and shock absorbers farther apart and outboard, nearer the edge of the truck providing more stability and a smoother ride; adding a second bumper to help with the yaw and provide more resting surface for the cabs when they’re stacked to reduce damage from bumps; a new cup around the bumpers to give them better load characteristics allowing them to flatten less than before and limiting cab sway; and centering the bumpers over the mating stop to allow the full face of the bumper to contact the stop, improving ride performance.
“This new suspension system for the International 9000 Series sleepers provides value to owners and delights the drivers,” says Allen Renfrow, product-development engineer for chassis-system engineering at International Truck and Engine Corporation. “And happy drivers recommend our vehicles to the people who make the buying decisions.”
Company officials say the changes will be especially appreciated when driving through cross-winds. The relocation of the shock absorbers and air bags provides for a smoother and more stable ride, International representatives claim.
