MACK® Twin Y™ and MACK mRIDE Suspensions Debut at MATS
Both Suspensions Now Available for Order
LOUISVILLE, KY (March 21, 2013) – Underscoring its commitment to meeting the needs of all customers, regardless of application, Mack Trucks today unveiled two new suspensions offered with proprietary MACK® axles for superior fuel efficiency, performance, ride and handling.
The MACK® Twin Y™ Air Suspension and MACK mRIDE spring suspension were showcased in the Mack booth at the 2013 Mid-America Trucking Show.
The Mack Twin Y Air Suspension is the trucking industry’s first suspension to utilize an innovative Y-shaped high-strength steel design. Delivering unmatched comfort, handling and fuel efficiency for highway customers desiring a smoother, more stable ride, the Twin Y is up to 403 pounds lighter than other air suspensions, offering customers a significantly lighter weight option.
Field-tested by customers 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, C150/151 and 200 Series carriers.
The Mack mRIDE spring suspension, now offered with Mack axles, is ideal for vocational customers demanding a durable, stable ride with greater articulation. Paired with the Mack C150/151 series axle carriers, the Mack mRIDE is available on the MACK Granite®, Titan by MACK, Mack Pinnacle Axle Forward and the MACK TerraPro® model trucks.
“Customers want a durable, rugged truck that gets the job done, but they also demand outstanding performance, handling and comfort,” said John Walsh, Mack vice president of marketing. “This is where Mack excels. The fully integrated Mack Twin Y and mRIDE suspensions featuring our proprietary Mack axles offer improved stability, fuel efficiency, and ultimately a greater ROI for our customers.”
Unique, Industry-First Twin Y Design Improves Stability and Control
The design of the Mack Twin Y air suspension includes two stamped high-strength steel Y-shaped blades per wheel end. Clamping the axle with both upper and lower axle seats, the Twin Y blades greatly reduce suspension windup and significantly improve tire traction and braking control, as well as increase tire life by up to 25 percent.
The axle seats are clamped to the axle housing by Huck U-bolts on both sides and never need to be re-torqued.
Bushings in the upper and lower axle seats offer greater roll control and deliver easier handling with a more comfortable ride. The Twin Y’s lighter weight and reduced torque reactivity means less maintenance and extended tire and component life, which also significantly improves customer ROI.
The Twin Y’s design means the load on the suspension is entirely on the air ride and not on the pivot bushing.
Mack mRIDE Absorbs the Work, Keeping Drivers Productive, Comfortable
The use of spring leafs over four separate rubber block packs on the mRIDE provides stability and articulation, while also allowing the needed clearance for larger tires and brake components required in construction and vocational applications.
In addition to being lighter than other spring suspensions, the mRIDE delivers a smoother ride, improved stability and greater ground clearance over difficult terrain. The Mack mRIDE provides constant ground contact for all wheels over its articulation range, which in turn maximizes traction on any jobsite.
The parallel pinion angles of the Mack axles extend the driveline joint life. Coupled with the greaseless mRIDE suspension, the offering boasts easier maintenance and is easier to align, contributing to reduced customer maintenance costs.
