All-wheel drive conversion for Acterra

Acterra trucks will now come with a factory-authorized all-wheel drive conversion as an option, announced Sterling Trucks. The feature targets a wide range of vocations, including construction, utilities and municipal and emergency services, the company said.

The feature, manufactured by Fabco Automotive Corp., is available immediately for all Acterra 4×2 versions, with conversions for Acterra 6×4 trucks expected later this year.

The Acterra Fabco all-wheel drive conversion is offered with front axle ratings of 12,000, 14,000 or 16,000 pounds, and comes with a choice of one-or two-speed transfer cases. It is available for Acterra products equipped with MBE and Caterpillar medium-duty engines and with transmission choices from DaimlerChrysler Powersystems, Eaton and Allison.

The conversion features a technologically-advanced offset front-drive carrier axle and four-shaft transfer case, designed to ensure a minimal increase in vehicle height of only four-to-six inches over standard height. Coupled with no step frame modifications, the product retains frame integrity and durability, maintains a low center of gravity and eliminates up to 300 pounds of weight, the company says. Superior driveline angles comply with industry standards, and a single piece forward driveshaft avoids the cost and weight of a two-piece shaft. The all-wheel drive system is engaged through two easy-to-reach electro-pneumatic switches located on the dash.
