The Mack Trucks mRIDE spring leaf over rubber block suspension, which Mack says is ideal for vocational customers needing improved stability and greater traction on jobsites, now offers additional weight savings for increased payload when paired with proprietary Mack axles, the company says.
Available at 40,000-lbs. and 46,000-lbs. suspension ratings and with standard track axles, customers can save 140 lbs. with drum brakes and 146 lbs. with air disc brakes as a result of casting suspension components into the Mack axle housing, Mack says. Mack axles are produced at Mack’s powertrain facility in Hagerstown, Maryland.
The mRIDE’s parabolic springs are thickest at the center to ensure the clamp load area offers the greatest strength and are tapered to improve driver comfort, the company says.
The spring leaf design and V-shaped torque rods ensure stability to efficiently transmit forces into the truck’s frame. Shock absorbers, along with rubber and steel shock towers, improve ride and handling, Mack says.
The mRIDE is fully integrated with Mack MP engines, transmissions and axles and can be spec’d in the Mack Pinnacle axle forward, Mack Granite, Mack TerraPro and Mack LR.
Mack also recently announced that it has enhanced its standard axle warranty for Model Year 2022 Mack models, extending time and mileage coverage. Mack vehicles available with the extended standard axle coverage include the Mack Anthem, Pinnacle, Granite, TerraPro and LR models.
