PRIMAAX®EX / PRIMAAX®for International Truck Vehicles
17730-283 3 Product Description
* Some vehicle configurations, such as vehicles equipped with outriggers, may require alternate suspension air valving. Contact vehicle manufacturer or
Hendrickson for more information.
PRIMAAX EX — MAAXimize the performance of vocational and heavy-haul vehicles with a
suspension engineered specifically for demanding on- and off- road conditions including, but
not limited to: truck, tractor, dump, front and rear discharge mixer, crane, refuse, drilling rig, log-
ging, platform, specialty and vehicles equipped with outriggers*.With more than 95 years of
robust suspension design,Hendrickson delivers another premium suspension with PRIMAAX EX.
Rugged, dependable and extensively tested in challenging applications, PRIMAAX EX paves a
new road for suspension technology.
■ Structural beams and cross beams — Advanced structural beams utilize premium materi-
als for high durability and reliability.Structural beams include integrated end caps that form
a solid connection with the square cross tube to form a rigid torsion system for improved
stability and control.
■ Unique suspension geometry — Optimized suspension geometry contributes to more
than twice the roll stability of competitive air suspensions,helps improve handling and roll
stiffness for expanded applications,and significantly controls suspension-induced driveline
vibration.
■ Large volume air springs — Reduce noise, vibration and harshness to cab, chassis and
body equipment for reduced total vehicle maintenance. Also reduce air pressure required
to lift and support loads.
■ QUIK-ALIGN®— Hendrickson’s proven QUIK-ALIGN axle alignment system helps save time
and money – offers a fast method to ensure proper alignment to reduce maintenance time
and help extend tire life.
■ D-pin axle connection and clamp group — Reduces stress input into the axle housing by
transferring the torsional loads to the integrated stabilizer system, which helps extend axle
and joint service life.
■ Heavy-duty shock absorbers — Positioned and tuned for optimum damping characteris-
tics and also protect air springs from overextension.
■ Premium heavy-duty torque rods and bushings — The three-rod configuration reduces
axle stress, welding and complexity. Optimized configuration contributes to exceptional
handling.Premium rubber bushings increase service life and resistance to bushing walkout.

■ SAFETY PRECAUTIONS
FASTENERS
DISCARD USED FASTENERS.ALWAYS USE NEW FASTENERS TO COMPLETE A REPAIR. FAILURE TO DO
SO COULD RESULT IN FAILURE OFTHE PART,OR MATING COMPONENTS,LOSS OF VEHICLE CONTROL,
PERSONAL INJURY,OR PROPERTY DAMAGE.
LOOSE OR OVER TORQUED FASTENERS CAN CAUSE COMPONENT DAMAGE, LOSS OF VEHICLE
CONTROL, PROPERTY DAMAGE, OR SEVERE PERSONAL INJURY. MAINTAIN CORRECT TORQUE
VALUE AT ALL TIMES. CHECK TORQUE VALUES ON A REGULAR BASIS AS SPECIFIED, USING A
TORQUE WRENCH THAT IS REGULARLY CALIBRATED.TORQUE VALUES SPECIFIED IN THIS TECHNICAL
PUBLICATION ARE FOR HENDRICKSON SUPPLIED FASTENERS ONLY. IF NON HENDRICKSON
FASTENERS ARE USED, FOLLOW TORQUE SPECIFICATION LISTED IN THE VEHICLE MANUFACTURER’S
SERVICE MANUAL.
QUIK-ALIGN FASTENERS
DISCARD USED QUIK-ALIGN FASTENERS.ALWAYS USE NEW QUIK-ALIGN FASTENERS TO COMPLETE
A REPAIR. FAILURE TO DO SO COULD RESULT IN FAILURE OF THE PART, OR MATING COMPONENTS,
LOSS OF VEHICLE CONTROL,PERSONAL INJURY,OR PROPERTY DAMAGE.
DO NOT ASSEMBLE QUIK-ALIGN JOINT WITHOUT THE PROPER FASTENERS.USE ONLY HENDRICKSON
GENUINE FASTENERS WITH SPECIAL COATING (H-COAT) TO SUSTAIN PROPER CLAMP FORCE.
FAILURE TO DO SO CAN CAUSE LOSS OF VEHICLE CONTROL, PROPERTY DAMAGE OR PERSONAL
INJURY AND VOID WARRANTY. ENSURE THAT THE QUIK-ALIGN FASTENER’S TORQUE VALUES ARE
SUSTAINED AS RECOMMENDED IN THE TORQUE SPECIFICATIONS SECTION OF THIS PUBLICATION.
FAILURE TO DO SO CAN CAUSE LOSS OF VEHICLE CONTROL RESULTING IN PERSONAL INJURY OR
PROPERTY DAMAGE.
LOAD CAPACITY
ADHERE TOTHE PUBLISHED CAPACITY RATINGS FOR THE SUSPENSION.ADD-ON AXLE ATTACHMENTS
AND OTHER LOAD TRANSFERRING DEVICES, SUCH AS LIFTABLE AXLES, CAN INCREASE THE
SUSPENSION LOAD ABOVE ITS RATED AND APPROVED CAPACITIES, WHICH CAN RESULT IN
COMPONENT DAMAGE AND LOSS OF VEHICLE CONTROL, POSSIBLY CAUSING PERSONAL INJURY
OR PROPERTY DAMAGE.
MODIFYING COMPONENTS
DO NOT MODIFY OR REWORK PARTS WITHOUT AUTHORIZATION FROM HENDRICKSON. DO NOT
SUBSTITUTE REPLACEMENT COMPONENTS NOT AUTHORIZED BY HENDRICKSON.USE OF MODIFIED,
REWORKED, SUBSTITUTE OR REPLACEMENT PARTS NOT AUTHORIZED BY HENDRICKSON MAY
NOT MEET HENDRICKSON’S SPECIFICATIONS,AND CAN RESULT IN FAILURE OF THE PART, LOSS
OF VEHICLE CONTROL, POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE, AND WILL VOID
WARRANTY.USE ONLY HENDRICKSON AUTHORIZED REPLACEMENT PARTS.
TORCH/WELDING
DO NOT USE A CUTTING TORCH TO REMOVE ANY FASTENERS.THE USE OF HEAT ON SUSPENSION
COMPONENTS WILL ADVERSELY AFFECTTHE STRENGTH OF THESE PARTS.A COMPONENT DAMAGED
IN THIS MANNER CAN RESULT IN THE LOSS OF VEHICLE CONTROL AND POSSIBLE PERSONAL
INJURY OR PROPERTY DAMAGE. EXERCISE EXTREME CARE WHEN HANDLING OR PERFORMING
MAINTENANCE IN THE AREA OF THE SUPPORT BEAM. DO NOT CONNECT ARC WELDING GROUND
LINE TO THE SUPPORT BEAM.DO NOT STRIKE AN ARC WITH THE ELECTRODE ON THE SUPPORT BEAM.

17730-283 7 Important Safety Notice
SHOCK ABSORBERS
THE SHOCK ABSORBERS ARE THE REBOUND TRAVEL STOPS FOR THE SUSPENSION. ANYTIME
THE AXLE ON A PRIMAAX EX / PRIMAAX SUSPENSION IS SUSPENDED IT IS MANDATORY THAT THE
SHOCK ABSORBERS REMAIN CONNECTED. FAILURE TO DO SO CAN CAUSE THE AIR SPRINGS TO
SEPARATE FROM THE PISTON AND RESULT IN PREMATURE AIR SPRING FAILURE. REPLACEMENT OF
SHOCK ABSORBERS WITH NON-HENDRICKSON PARTS CAN ALTER THE REBOUND TRAVEL OF THE
SUSPENSION.
AIR SPRING INFLATION AND DEFLATION
PRIOR TO DISASSEMBLY OF THE SUSPENSION, AIR SPRING ASSEMBLIES MUST BE DEFLATED.
UNRESTRICTED AIR SPRING ASSEMBLIES CAN VIOLENTLY SHIFT. DO NOT INFLATE AIR SPRING
ASSEMBLIES WHEN THEY ARE UNRESTRICTED. AIR SPRING ASSEMBLIES MUST BE RESTRICTED
BY SUSPENSION OR OTHER ADEQUATE STRUCTURE. DO NOT INFLATE BEYOND PRESSURES
RECOMMENDED BY AIR SPRING MANUFACTURER, CONTACT HENDRICKSON TECHNICAL SERVICES
FOR DETAILS. IMPROPER USE OR OVER INFLATION MAY CAUSE AIR SPRING ASSEMBLIES TO BURST,
CAUSING PROPERTY DAMAGE AND/OR SEVERE PERSONAL INJURY.
PRIOR TO AND DURING DEFLATION AND INFLATION OF THE AIR SUSPENSION SYSTEM, ENSURE ALL
PERSONNEL AND EQUIPMENT ARE CLEAR FROM UNDER THE VEHICLE AND AROUND THE SERVICE
AREA, FAILURE TO DO SO CAN CAUSE SERIOUS PERSONAL INJURY, DEATH, OR PROPERTY DAMAGE.
AIR SPRING INFLATION
INFLATE THE SUSPENSION SLOWLY AND MAKE SURE THE RUBBER BLADDER OF THE AIR SPRING
INFLATES UNIFORMLY AND IS NOT BINDING. FAILURE TO DO SO CAN CAUSE DAMAGE TO THE AIR
SPRING AND/OR MOUNTING BRACKETS AND VOID WARRANTY.
AIR SPRING LOWER MOUNTING STUDS
IF THE AIR SPRING IS BEING REMOVED, IT IS MANDATORY TO LUBRICATE THE LOWER AIR SPRING
FASTENERS WITH PENETRATING OIL AND REMOVE WITH HAND TOOLS TO PREVENT DAMAGE TO THE
LOWER AIR SPRING MOUNTING STUD. FAILURE TO DO SO CAN CAUSE COMPONENT DAMAGE AND
VOID WARRANTY.
AIR SPRING PRESSURE RETENTION
SOME VEHICLE APPLICATIONS, SUCH AS VEHICLES EQUIPPED WITH OUTRIGGERS, RETAIN SOME AIR
PRESSURE IN THE AIR SPRINGS AT ALL TIMES.PRIOR TO PERFORMING ANY MAINTENANCE, SERVICE,
OR REPAIR OF THE SUSPENSION,VERIFY EACH AIR SPRING IS COMPLETELY DEFLATED. FAILURE TO
DO SO COULD RESULT SERIOUS PROPERTY DAMAGE AND/OR SEVERE PERSONAL INJURY.
FAILURE TO PRESS THE AIR SPRING AGAINST THE UNDERSIDE OF THE FRAME WHILE TIGHTENING
THE UPPER AIR SPRING BRACKET CAN RESULT IN COMPONENT DAMAGE AND PERSONAL INJURY OR
PROPERTY DAMAGE.
PROCEDURES AND TOOLS
A TECHNICIAN USING A SERVICE PROCEDURE OR TOOL WHICH HAS NOT BEEN RECOMMENDED
BY HENDRICKSON MUST FIRST SATISFY HIMSELF THAT NEITHER HIS SAFETY NOR THE VEHICLE’S
SAFETY WILL BE JEOPARDIZED BY THE METHOD OR TOOL SELECTED. INDIVIDUALS DEVIATING IN
ANY MANNER FROM THE INSTRUCTIONS PROVIDED WILL ASSUME ALL RISKS OF CONSEQUENTIAL
PERSONAL INJURY OR DAMAGE TO EQUIPMENT INVOLVED.
TRANSVERSE RODS
PRIMAAX EX / PRIMAAX SUSPENSIONS INCORPORATE TRANSVERSE RODS FOR VEHICLE STABILITY.IF
THESE COMPONENTS ARE DISCONNECTED OR ARE NON-FUNCTIONAL THE VEHICLE SHOULD NOT
BE OPERATED.FAILURE TO DO SO CAN RESULT IN ADVERSE VEHICLE HANDLING AND POSSIBLE TIRE
CONTACT WITH THE FRAME. OPERATING A VEHICLE WITH NON-FUNCTIONAL TRANSVERSE TORQUE
RODS CAN RESULT IN LOSS OF VEHICLE CONTROL, SEVERE PERSONAL INJURY,AND PREMATURE
COMPONENT DAMAGE.
