Mack Twin Y Air Suspension Wins 2013 Swedish Steel Prize

Overdrive Staff | November 26, 2013

The Mack Twin Y Air Suspension won the 2013 Swedish Steel Prize, an annual award recognizing the world’s most innovative design utilizing high-strength steel. The award was given by SSAB during an event Nov. 21 in Stockholm, Sweden. Mack Trucks was one of four finalists for the award.

The Mack Twin Y air suspension is the trucking industry’s first suspension to utilize high-strength steel in a Y-shaped design. The strong, yet lightweight design reduces suspension windup and improves tire traction and braking control. 

Mack will donate the 10,000 euros ($13,400) SSAB awarded to the Wounded Warrior Project, a non-profit that empowers wounded service members in the United States, raising public awareness and providing unique, direct programs to meet the needs of injured servicemen and women.

The Twin Y Air Suspension was introduced in January 2013. It utilizes two stamped high-strength steel Y-shaped blades at each wheel end. Along with improved tire traction and braking control, the suspension also offers a stable ride, better handling and gains in fuel efficiency. Because of the greater flexibility of the steel and the reduced torque reactivity and lighter weight design of the Twin Y, truck components last longer and tire life is extended.

Available on the Mack Pinnacle Axle Back and Axle Forward models, the Twin Y is paired with the Mack S38 and S40 series axles and C125/126 and C150/151 carriers. The load of the suspension is completely on the air ride and not on the pivot bushing.
