LIGHTWEIGHT – More Payload | Quiet, Cushioned Ride | LOW MAINTENANCE
SUspension
There’s a reason Freightliner’s AirLiner® rear suspensions shoulder the weight of more vehicles in North America than any other suspension. With the most
advanced design on the road, our family of AirLiner suspensions keeps weights lower and payloads higher. Smart engineering means drivers, and their freight, get
a quiet and cushioned ride, reducing driver fatigue and the possibility of damaged cargo. In addition, maintenance-friendly features ensure a long life and minimize
maintenance costs year after year.
LIGHTWEIGHT – More Payload Capacity
•Advanced design reduces weight, allowing for greater revenue-earning payload
• Fewer total parts offer more simplicity and less weight
• Aluminum brackets used on all but the 23,000 and 46,000 pound models
• Composite or aluminum air bag pistons used on all models to reduce weight
• Lightweight standard-duty design rated at 40,000 pounds, higher than most
competitors’ standards at 38,000 pounds
FULL SELECTION – Almost Any Application
• Full selection of single and tandem drive suspensions tuned for almost
any application
• For larger payloads, a 46,000 pound AirLiner Heavy-Duty version is
available with a C-channel crossbeam stabilizer

RIDE AND HANDLING – Optimized for Performance
• Optimized suspension geometry provides superior handling, excellent lateral
control and enhanced roll stability
• Freight-cushioning ride, dynamically tuned to the vehicle, reduces damage
to payloads
• Proven combination of trailing arm leaf springs and self-leveling air bags
provides a uniformly soft spring ride
• Excellent ride either loaded or unloaded
• Designed to reduce sway when turning or negotiating curves
• Delivers greater comfort and handling when compared to other suspensions
• Underslung, parabolic leaf-spring trailing arms permit low fifth wheel heights
for today’s tallest trailers
• Premium rotary height-control valve provides for a constant spring rate for
optimum cushioning performance and ride height
LOW MAINTENANCE – Lower Cost of Ownership
• Substantially fewer parts than competing systems provide reduced
maintenance and greater reliability
• Double-bonded rubber bushings on moving joints require no lubrication,
reducing maintenance costs and ensuring metal parts don’t rub together,
increasing product life
• No wear surface points to lubricate or replace
ECONOMICAL – Low Cost, High Resale
• Attractively priced
• Resale price comparisons show trucks with air ride suspensions command
higher resale value
