Meritor Inc has unveiled the newest suspension family members—the MTA25 (25,000-lb capacity) and MTA30 (30,000-lb capacity)—to its line of trailing-arm air ride trailer suspension systems. The Meritor Trailing-Arm Air (MTA) suspension is designed to meet the needs of North America truck and trailer operators in vocational markets.
Both suspensions, plus the previously offered MTA23, are available with the company’s new optional lift kit. This quick-response system allows MTA suspension system users to efficiently raise select axles, which improves maneuverability and extends tire life. Available in painted or galvanized finishes, the lift kit attaches easily and can be installed as original equipment (OE) or field retrofit.
Introduced in 2010, the MTA23 was the first member of the new suspension systems family. The two new models join it to complete the company’s lineup of top-mount air-ride suspension systems. They will be joined by new low-mount models in summer 2012. The new suspension systems feature six technology advancements with these benefits:
•Durability—the MTA design outperforms competitive products two-to-one in laboratory and track testing.
•Light weight—one of the lightest-weight suspensions in its market segment.
•Patent-pending axle wrap design—foundation for a secure and durable axle connection.
•Larger, more robust shock absorbers—specifically tuned to the MTA suspension with three times the damping power. The larger-bore design provides greater suspension control and more consistent tire contact with the ground, reducing tread wear, improving braking, and enhancing handling.
•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.
•Lift kits—quick-lifting response, light weight, durable, easy to install and maintain, and designed to mount under the frame brackets to prevent interference with tires.
The MTA trailer suspension system is integrated with Meritor trailer axles and Q Plus Cam Brakes. All are covered by a 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.
