Air Suspension for Tridem Axles

AD Series ● 100% off-highway rated performance.

● Designed for maximum durability in challenging operational environments. ● Non-torque reactive design maintains proper pinion angle to reduce unwanted driveline vibration and noise while helping increase driveline component life. ● Propriety SAF-Holland rubber bushings and Sachs shocks are standard for increased durability and service life. Developed for severe duty applications characterized by: – Heavy vertical loads – High gross combined weights – High torque drive trains

– High center of gravity loads – Significant off-highway travel

Severe and Heavy Duty Applications Include: ● Heavy haul/heavy construction ● Mine/Pit/Quarry

● Logging ● Oilfield

● Mixers and dumps for aggregate ● Asphalt and concrete transfer ● Straight truck in municipal, utility, and maintenance
