Meritor adds to MTA suspension family

Meritor Inc announced the production of the MTA25 low-mount and MTA30 low-mount trailer suspensions, the two newest family members of its MTA (Meritor Trailing-Arm Air) suspension series for North American trailer operators.

These units are specifically designed as part of a fully integrated system to optimize performance and weight, and are ideal for vocational applications like single-drop flatbed, double-drop flatbed, loggers, and chip hauler trailers.

The MTA lineup now includes the MTA23 (23,000-lb capacity), the top-mount MTA25 (25,000-lb capacity), the top mount MTA30 (30,000-lb capacity), and the two newest low-mount products. All MTA models are available with the optional lift kit, a quick-response system that efficiently raises select axles, improving maneuverability and extending tire life. Available in painted or galvanized finishes, the lift kit attaches easily and can be installed as original equipment or field-retrofitted.

The two new low-mount suspension systems feature improvements and technology advancements including:

  • Durability — The MTA design outperforms leading competitive products two-to-one in laboratory and track testing.

  • Light weight — one of the lightest suspensions in its market segment.

  • Patent-pending, axle-wrap design — foundation for a secure and durable axle connection.

  • Patented pivot bushing — absorbs road inputs resulting in a softer ride, more cargo protection and reduced stress on the trailer's structure. Patented steel interleaf shims in the bushing provide superior fore-aft stiffness aiding in improved axle alignment, better tire wear, and reduced roll steer.

  • Higher damping shock absorber — provides improved road-to-tire contact and contributes to better braking and longer tire life.

The MTA trailer suspension system is integrated with Meritor trailer axles and Q Plus Cam Brakes. All are covered by the company's five-year, 500,000-mile warranty on structural components. Optional components include air disc brakes, automatic slack adjusters, the SteelLite X30 drum and lightweight hub, and the Meritor Tire Inflation System (MTIS) by PSI.
