Ridewell says its RAR-260 trailer air-ride suspension — available in overslung and underslung configurations for both 25,000- and 30,000-pound capacities — is suited for any application and is manufactured with Securelok pivot nuts to maintain pivot clamping force. The unitized nut, washer and shim combination is designed to resist loosening under vibration.
Additional features, according to the company, include Tenneco multifunctional bushing, integrated shock-absorber mounting, a pivot bolt that requires only 500 ft.-lbs. of torque, axle-alignment adjustment capability of plus or minus .25 inch at the hanger, and mounting heights that range from 14 to 18 inches for the overslung configuration and 5.5 to 9 inches for the underslung model.
