Severe service truck makes debut at contruction industry's biggest show

LAS VEGAS, Nev. (March 12, 2008)
– The heavy-duty construction market has a new powerhouse.The newest truck model in the proven PayStar line – the International® PayStar® 5900i Set-Back Axle (SBA) was introduced at the CONEXPO-CON/AGG Show held in Las Vegas March 11-15, 2008.

The new Paystar 5900i SBA is a class 8 vocational on/off-highway vehicle that features a new axle configuration to meet the needs of customers in severe service applications such as construction, oilfield, logging, heavy-hauling, mining, recovery and more.

Powered by Caterpillar or Cummins diesel engines up to 15-liter and up to 625 horsepower, the PayStar 5900i SBA is built on the strength of a standard 12.25-inch frame rail PayStar chassis. It provides the highest standard strength-to-weight ratio with RBM ratings at 2.3 million RBM. An optional double frame rail provides an increase to 4.7 million RBM.

The 5900i SBA offers the widest aluminum cab in the industry and comes with standard Whisper Cab® sound insulation package for a comfortable environment. The sloped hood was designed for better visability on the jobsite.

This newest model adds to a robust International big-bore line-up, which includes the PayStar 5500i, 5600i and 5900i set forward axle models and WorkStar 7600 and 7700 models.
