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.
