FRANKFORT, KY. ArvinMeritor has introduced a new family of trailing arm air suspensions for platform, tank, dump and other vocational trailer applications. The first Meritor Trailing-Arm Air (MTA) suspension -- a 23,000-lb. capacity top-mount mode – goes into full production this fall. It will be followed by five other top- and low-mount models with capacities up to 30,000 lbs., all produced at ArvinMeritor’s trailer axle plant in Frankfort, Ky.
Technology highlights for the new air-ride includes a patented pivot bushing designed to provide a soft ride while also offering firm lateral control for good roll stability and better tire wear; larger shock absorbers specifically tuned for the MTA, and a new axle wrap design that cuts weight while improving durability.
Replacing the company’s current RFS Series of trailing-arm air suspensions, the new MTA also features integrated Meritor Q Plus cam or air disc brakes. Other integrated options include ArvinMeritor’s automatic slack adjusters, SteelLite drum and lightweight hub, and the Meritor Tire Inflation System.
Warranty for the MTA will be five years, 500,000 mi.
