Meritor adds two new ratios for 14X tandem drive axle

TROY, Mich. — Meritor is offering two new ratios for its 14X rear-drive axle for improved fuel economy, the company announced.

The company will offer the 14X tandem drive axles with a 2.79 ratio beginning in June, while a 2.85 ratio will be launched later this summer. The axles, when combined with the Eaton/Cummins SmartAdvantage powertrain, will allow for greater downspeeding, allowing the engine to cruise at lower rpms.

“With these new axle ratios, drivers will experience a fuel-economy ‘sweet spot’ at road speeds of 62 to 65 mph,” said Ken Hogan, general manager, axles, North America for Meritor. “We’ve optimized this engine-transmission-axle combination to deliver uncompromising performance and efficiency.”

Customers are urged to consider how the engine, transmission, axles and tire sizes all interact when spec’ing new trucks, Hogan said.

“The new axle ratios specifically target the needs of fuel efficiency-minded customers and are another example of how we are continually creating and updating our offerings to better-serve the industry,” he said.
