Meritor’s new MTA25 and MTA30 low-mount trailer suspensions are now in production. First announced a year ago, the two newest MTA (Meritor Trailing-Arm Air) suspensions are specifically designed as part of an integrated system to optimize performance and weight. They’re aimed at vocational applications like single-drop flatbed, double-drop flatbed, loggers, and chip trailers.
The MTA lineup now includes the MTA23 (23,000-lb capacity), the top-mount MTA25 (25,000 lb), the top-mount MTA30 (30,000 lb) and the two newest low-mount products.
All MTA models are available with the optional lift kit, a quick-response system that 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, says Meritor.
The two new suspensions feature a “unique” patent-pending, axle-wrap design that’s the foundation for a secure and durable axle connection. A patented pivot bushing is said to absorb 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. MTA suspensions are said to be among the lightest in their market segment.
The MTA 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.
