drive axle delivers every benefit of its predecessor, the legendary Meritor
RT-40-145 - and more. Including a more robust 20 percent larger Inter-Axle (IAD)
to handle today's higher-torque engines. It features as standard equipment the
smooth, efficient performance of our premium Meritor Amboid™

Features and Benefits
The 14X tandem drive axle features a more robust
Inter-Axle Differential (IAD) that is 20 percent larger than its competition
with fewer parts; ability to handle up to 2,050 lbs. per foot of torque in
certain applications. Additionally, it includes new IAD needle bearings system
for reduced heat and wear, which delivers increased reliability.
Its premium Amboid design is now standard for
improved driveline angles that reduce vibration while increasing ride quality
and overall component life. Amboid gearing on the rear drive axle allows
parallel positioning between forward and rear drive axles.
This axle offers the industry's most complete ratio
range - 2.47 to 7.17 range can match your application and specific engine
manufacturer's recommendations. The new 2.47 ratio is the industry's fastest
axle ratio and is also the most efficient solution for vehicles with direct
The use of wide-based tires with optional DualTrac
housing is another available option. This offers bearing life equal to
dual-tire-configured tandem axles, while allowing the ability to convert between
wide-based single tires and duals within legal axle spread dimensions. DualTrac
is offered in 9.5 mm and 11.0 mm housing wall thickness options.
With an industry-leading axle breather, designed for
today's extended-drain synthetic lubes, water and other contaminants are
prevented from entering the axle while keeping lube in place.
