PRIMAAX®EX / PRIMAAX®for Volvo Vehicles
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.
