Mack Trucks has launched its Twin Y Air Suspension, with a new Y-shaped high-strength steel design, which is offered with proprietary Mack axles. The OEM also announced the availability of Mack proprietary axles on its mRide spring suspension.
The new Mack Twin Y suspension, according to the manufacturer, is up to 400 lbs. lighter than other air suspensions. Available on Mack Pinnacle Axle Back and Axle Forward models, the Twin Y features Mack S38 and S40 series axles with C125/126 and C150/151 carriers. The design of the new air suspension puts the load entirely on the air ride and not on the pivot bushing. Included are two stamped high-strength steel Y-shaped blades per wheel end, which are joined to the axle with upper and lower axle seats to reduce suspension windup and improve tire traction and braking control, and axle seats that are clamped to the axle housing by Huck U-bolts on both sides, the maker added.
The Mack mRide spring suspension, paired with C150/151 series axle carriers, is available on Mack Granite, Titan, Pinnacle Axle Forward and TerraPro model trucks. mRide features spring leafs over four separate rubber block packs, which offer stability and articulation that provides constant ground contact for all wheels, in turn maximizing traction. The design, Mack adds, also allows clearance for larger tires and brake components required in construction and vocational applications.
