Kenworth has recently released three new options for vocational trucks: a box bumper available on the T880, Allison’s 4700 RDS 7-speed automatic transmission, and a fixed grill option for the W900S with the PACCAR PX-9 in a set-forward front axle configuration.

The box bumper is compatible with the Kenworth T880 (both short and standard sizes) and features a unique tapered design for hood pivot clearance. The steel bumper comes in either ¼ or 3/8-inch in diameter, while the chrome version is available in ¼-inch diameter. It is available in aluminum or steel. In addition, it offers additional protection for the grille and headlight region.

For the Allison 4700 RDS 7-Speed transmission is now available for T880, T800, W900 and C500 models. The transmission has an optional second “deep reverse” and is part of the Allison Rugged Duty series. It is intended for customers operating dumps, mixers, heavy-haulers, and cranes. This is ideal for situations where there is an increase in transmission ratios.

“It’s a great choice for our customers operating mixers, dumps, cranes, and heavy-haulers, where the application calls for an increase in overall transmission ratios,” said Kurt Swihart, marketing director. “In the construction world, trucks often need better speed control for job-site maneuverability in steep and often tricky terrain. That’s the beauty of the Allison 4700 RDS, as it offers a lower reverse ratio, and a lower first gear ratio for maneuverability. The new Allison transmission also features no-power interrupts, which gives full power shifts and allows full use of the engine’s horsepower.”

The fixed-grilled is now available for W900S models in the set-forward front axle configuration with the Paccar PX-9. The grille is optimal for crane operators as well as vacuum trucks with boom supports or a steady leg. According to Swihart, the fixed grille option, “allows our customer or body builder to utilize the front of the truck without impacting the ability to open the hood. This option is especially useful for crane operators or those using the W900S as vacuum trucks with a ‘steady leg,’ or boom supports.”
