International® PayStar® 5900 Set-Back Axle Now Available with 10-Inch Frame Rails
Expanded Product Options Provide Customers with Additional Flexibility

LAS VEGAS (February 3, 2009) – To meet the needs of vocational truck customers looking for a lighter-weight and more nimble truck chassis, the International® PayStar® 5900 Set-Back Axle will now be available with 10-inch frame rails.

While the more traditional 12.25-inch frame rails will remain a standard option for the PayStar®, smaller, lighter-weight 10.25-inch frame rails will provide customers and truck equipment manufacturers (TEMs) with additional flexibility for a variety of unique on- and off-highway severe service applications.

“We’re always listening to our customers to deliver the products and options they need,” said Jim Hebe, Navistar senior vice president, North American sales operations. “Offering a lighter-weight, smaller frame rail option gives our customers the flexibility they require while maximizing payload.”

The smaller, lighter frame rail option will provide a distinct advantage for vocational tractor customers looking to take advantage of standardized trailer heights in straight dump, dump trailer and combination truck-trailer applications. In addition, for states with highly sensitive weight restrictions, the 10.25-inch frame rails could reduce total vehicle weight by as much as 90 lbs., providing customers with additional payload capacity, with a direct impact on the bottom line.
