Advanced technology in the MTA trailer suspension system sets new standards in ride, handling, tire life and durability. Exhaustive modeling, analysis and prototyping have led to an innovative structure and manufacturing process which has been validated in the laboratory, on independent proving grounds and in real-world applications. The result is a suspension system that meets the needs of North America’s demanding vocational market. Three top-mount models ranging from 23,000-lb. to 30,000-lb. capacities and two recently introduced low-mount models in 25,000-lb. and 30,000-lb. capacities optimize performance and weight.
Features & Benefits
Increased durability
- The innovative axle wrap, with its continuous robotic welds, eliminates high-stress concentrations
- Large-bore, high-damping shock absorber is tuned to the suspension, allowing for greater control and protection against air spring overextension
Excellent handling and ride quality
- The MTA is one of the lightest suspensions in its market segment, allowing for larger payloads
Better braking and tire life
- High-damping shock absorber offers 2.5 to 3.5 times the damping force of leading competitors with better tire-to-road contact to improve braking performance and extend tire life
Ease of maintenance
- Unique lightweight, stamped brake spider includes a patented, easy-service, bolt-on bushing retainer and allows for service or replacement of components without removing the hub
- Pivot-and-alignment connection features a unique collar design for simple and convenient axle re-alignment
- Plug-and-play design for simple installation, designed to fit common installation envelopes on a variety of trailer frames
Integrated design
- All elements are designed as part of a fully integrated system to optimize system performance and weight:
- Integrated Cummins-Meritor genuine axles, from the industry leader and world’s largest manufacturer of trailer axles
- Variety of brakes and wheel-end components optimize weight and improve braking performance
- Cummins-Meritor Tire Inflation System (MTIS™) maintains proper and even tire inflation, reducing wear and increasing fuel economy.
- Standard ThermALERT™ wheel-end heat-sensing technology immediately alerts drivers to overheating wheel-ends so that drivers can take preventive action to avoid damage
- Optional lift kits available
