Kenworth’s T370 is now available with several Meritor heavy duty axle options: MFS20 non-drive front steer axles rated 16,000, 18,000 and 20,000 pounds, and MT-44 and RT-46 rear tandems with 44,000- and 46,000-pound capacities, the company announced. They are in addition to Dana axles previously offered. 

“The expanded axle offering will now enable operators to leverage the T370 for a broader range of vocational applications that require 20K front and 46K rear suspensions such as dump, fuel, utility, crane, service trucks, or mixers,” said Jason Skoog, Kenworth assistant general manager for sales and marketing.

The MFS20 front axles, available with 16,000-, 18,000-, and 20,000-lb. gross axle weight ratings, include a heavy-duty, cross-brace-reinforced front frame assembly, bolted cross members and either 10-5/8-inch frame rails with insert or 10 3/4-inch frame rails. Full inserts are available for both of these rail sizes.

Iron hubs, drum brakes, and dual-power steering gears, along with a power steering cooler, complete the lighter engine/higher-capacity front axle combination.

Meritor says the MFS20 features a sharp wheel cut and short turning radius for good maneuverability, and uses an EasySteer king pin and bushings. I-beam construction delivers proven durability and long life for tires.

The MT-44 and RT-46 tandem rear axle models offer a broad range of gear ratios for varying applications and operations. A rugged single-piece carrier supports precise gear alignment, and a low-maintenance tandem design extends the range up to 500,000 miles between lube changes.

Along with the new Meritor axles, the T370 is now available with heavy-duty rear suspensions rated up to 46,000 pounds from a variety of leading suppliers in either spring or air configurations. The truck is powered by the PX-9 diesel.

“The Paccar PX-9 offers excellent power in a smaller footprint to move more weight,"  Skoog said. "Coupled with the higher-capacity Meritor front axles, customers can have more of the payload’s weight shifted to the steer axle and still take advantage of the T370’s short bumper-to-back-of-cab (BBC) measurement.”
