Mack Raises the Bar with Suspensions Featuring Proprietary MACK Axles

MACK Twin Y Air Suspension and MACK mRIDE Offer Customer Benefits

Mack Trucks has launched its breakthrough MACK Twin Y Air Suspension, the trucking industry’s first suspension to utilize an innovative Y-shaped high-strength steel design.

Offered with proprietary MACK axles, the Mack Twin Y Air Suspension delivers unmatched comfort, handling and fuel efficiency for highway customers desiring a smoother, more stable ride. The Twin Y is up to 400 pounds lighter than other air suspensions, offering a significantly lighter weight option for customers.

Mack also announced the availability of Mack proprietary axles on its MACK mRIDE spring suspension, ideal for vocational customers demanding a durable, stable ride with greater articulation.

“The Mack Twin Y and Mack mRIDE are designed specifically for what customers have told us they need to be successful,” said John Walsh, Mack vice president of marketing. “Both of these suspensions benefit from our Mack proprietary axles, which provide even greater stability and fuel efficiency.”

Design of Mack Twin Y Key to Improved Control, Stability

Customer field tested for more than three million miles and available on the MACK Pinnacle Axle Back and Axle Forward models, the MACK Twin Y features MACK S38 and S40 series axles with C125/126 and C150/151 carriers.

The design of the Mack Twin Y air suspension includes two stamped high-strength steel Y-shaped blades per wheel end. The Twin Y blades are joined to the axle with both upper and lower axle seats, which greatly reduces suspension windup and significantly improves tire traction and braking control.

Mack mRIDE for the Tough, Vocational Applications

The Mack mRIDE spring suspension, paired with the Mack C150/151 series axle carriers, delivers superior performance for vocational applications and is available on the MACK Granite, Titan by MACK, Mack Pinnacle Axle Forward and the MACK TerraPro model trucks.

The use of spring leafs over four separate rubber block packs offer stability and articulation, while also allowing the needed clearance for larger tires and brake components required in construction and vocational applications.
