17730-254 3 Product Description
■
Genuine Hendrickson torque rods — Optimized configuration helps improve handling and
roll stiffness for expanded applications.
■
QUIK-ALIGN
®
— Allows for easy axle alignment without shims. Reduces maintenance time
and helps extend tire life.
■
Air springs — Large volume, low frequency design for premium ride quality. Advanced
design air springs lift and support the load with less air pressure.
■
Structural beams / cross beams — Cast structural beams form a solid connection with
the square cross brace to form a rigid torsion and stabilizer system. Redesigned structural
beams utilize premium materials and are proven in some of the most challenging environ-
ments. Integrated beam end cap allows for a maintenance-free connection with the cross
beam for increased uptime. Robust rubber bushings improve service life and eliminate
lubrication requirements.
■
Heavy-duty shock absorbers — Positioned and tuned for optimum damping characteristics.
■
Axle connections — D-pin axle connection decreases torsional axle stress for reduced main-
tenance and increased joint integrity. Integrated axle stop contact pads reduce axle stress.

1. Operators using vehicles equipped with liftable push or tag axles must not exceed published ratings. Ratings are
limited to no more than five percent of vehicle operation at a speed not to exceed five mph. Liftable pusher or tag
axles should be raised (or unloaded) to improve vehicle maneuverability in off-road use or when vehicle is empty.
Site travel ratings are consistent with specifications and must not be exceeded.
2. Axle travel may be limited by vehicle manufacturer; axle stop settings may restrict suspension’s articulation.
3. For different ride height options, please contact Hendrickson, your vehicle manufacturer or authorized vehicle
dealer for further information.
