Mack Raises the Bar with Suspensions Featuring Proprietary MACK Axles
GREENSBORO, NC (Jan. 28, 2013) - Mack Trucks today
launched its breakthrough MACK(r) Twin Y(tm) Air Suspension, the
trucking industry's first suspension to utilize an innovative Y-shaped
high-strength steel design.
Offered with proprietary MACK(r) 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 today the availability of Mack proprietary axles
on its MACK(r) 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(r) Pinnacle(tm) Axle Back and Axle Forward
models, the MACK Twin Y features MACK(r) 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.
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 and a more comfortable ride. Lighter
weight and non-torque reactive, the Twin Y requires less maintenance
and extends tire and component life, significantly improving customer
The Twin Y's design means the load on the suspension is entirely on
the air ride and not on the pivot bushing.
"The industry has never before seen an air suspension system
engineered like the Mack Twin Y," said Jerry Warmkessel, Mack
marketing product manager for on-highway. "Offered with Mack axles for
even greater fuel efficiency, the Twin Y air suspension sets the bar
for the industry. Our customers demand a good ride at a competitive
cost and lower weight. We're offering all of that and more with the
Mack Twin Y."
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(r), Titan
by MACK, Mack Pinnacle Axle Forward and the MACK TerraPro(tm) model
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
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.
"The completely integrated drivetrain offered by a Mack
MP engine, Mack transmission, Mack axles and now the Mack mRIDE
suspension creates superior performance, stability and handling," said
Curtis Dorwart, Mack vocational marketing product manager. "Mack
vocational customers can count on mRIDE-equipped trucks to absorb more
of the rough work on jobsites, keeping drivers more comfortable and
