SECTION 2

Product Description
STEERTEK NXT - Integrated into the AIRTEK/SOFTEK system, the box-shaped design provides a
stiffer axle and resists torsional, longitudinal and vertical loads more effectively than traditional
I-Beam axles. Together with the front limbs of the leaf springs, the fabricated axle beam forms a
torsion system, enhancing roll stability characteristics and improving handling.
Axle Clamp Group - The Clamp Group consists of the top pad,%" hex bolts I U-bolts, washers, and nylon locknuts
Integrated Axle Seats - Integrated axle seats to improve ground clearance, reduce part
count, and simplify assembly.
Adjustable Tie Rod - To help maximize tire life, the tie rod easily adjusts toe-in/out.
Steering Knuckles - The steering and tie rod arms are integrated for increased strength
and reduced weight. The unique steering knuckle packaging delivers up to a maximum of
50° wheel cut. The two piece knuckle design makes replacing the kingpin bushings easier
by eliminating the need to remove the kingpins.
AIRTEK- Winner of the 2001 Automotive News and Cap Gemini Ernst & Young PACE Award
for Product Innovation. AIRTEK is an integrated front air suspension and fabricated steer axle
that work together to form an integrated torsion system. This lightweight system provides driver
comfort and is ideal for a variety of applications. Utilizing a system approach, Hendrickson has
engineered and optimized the following components to form a system delivering superior ride,
stability and handling characteristics with reduced weight and maintenance.

AIRTEK® • SOFTEK® for Blue Bird Buses
Air Springs - Exclusive to Hendrickson, the lightweight air springs deliver a soft ride. The
air springs are engineered to support 78% of the vertical load while providing a low spring
rate. The quick "snap" design for the 10,000 pound capacity, the bolt on design for the
13,200/14,600 pound capacity, and the "push-to-connect" air supply design also provide
fast and easy installation and removal.
Leaf Spring Assembly - With its innovative design, the leaf spring provides superior stability, performance and a soft ride. The patented leaf spring shares loads equally with the air
spring. Durable rubber front and patented rear bushings are greaseless and only require
periodic inspections.
SOFTEK - is an integrated front mechanical suspension and robotically welded steer
axle that work together to form an integrated torsion system. Utilizing a system approach,
Hendrickson has engineered and optimized the following components to form a system
delivering ride, stability and handling characteristics with reduced weight and maintenance.
Leaf spring assembly - With its innovative design, the leaf spring provides superior stability, performance and a soft ride. Durable rubber front and patented rear bushings are
greaseless and only require periodic inspections.
Shock absorbers - AIRTEK/SOFTEK utilizes premium shocks that have been tested and tuned
specifically for the suspension system.
Frame brackets - Optimized design delivers weight reduction and proven durability. The front
and rear frame brackets are common between the AIRTEK/SOFTEK suspensions.

A

WARNING

FASTENERS
DISCARD USED FASTENERS. ALWAYS USE NEW 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.
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 REGULARLY
CALIBRATED TORQUE WRENCH. 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.

A

DANGER

AIR SPRINGS
AIR SPRING ASSEMBLIES MUST BE DEFLATED PRIOR TO LOOSENING ANY CLAMP GROUP HARDWARE.
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.

A

WARNING

WHEN SERVICING THE VEHICLE OR ATTACHING AN AIR SPRING AND THE VEHICLE IS ON THE GROUND,
PRIOR TO AIRING THE SUSPENSION SYSTEM MAKE CERTAIN THE AIR SPRING LOCATOR IS INDEXED
INTO THE UPPER AIR SPRING BRACKET PROPERLY, AND THE AIR SPRING IS FULLY SEATED ON THE
SPRING TOP PAD. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN PREMATURE AIR
SPRING FAILURE, CAUSE PERSONAL INJURY, OR PROPERTY DAMAGE.

A

WARNING

PRIOR TO AND DURING DEFLATION AND INFLATION OF THE FRONT AIR SUSPENSION SYSTEM,
ENSURE THAT 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.

A

WARNING

LOAD CAPACITY
ADHERE TO THE PUBLISHED CAPACITY RATINGS FOR THE SUSPENSIONS.ADD-ON AXLE ATTACHMENTS
(I.E. SLIDING FIFTH WHEELS) AND OTHER LOAD TRANSFERRING DEVICES CAN INCREASE THE
SUSPENSION LOAD ABOVE THE RATED AND APPROVED CAPACITIES WHICH CAN RESULT IN FAILURE
AND LOSS OF VEHICLE CONTROL, POSSIBLY CAUSING PERSONAL INJURY OR PROPERTY DAMAGE.

A

WARNING

SHOCK ABSORBERS
THE SHOCK ABSORBERS ARE THE REBOUND TRAVEL STOPS FOR THE SPRINGS. ANYTIME THE FRONT
AXLE ON AN AIRTEK SUSPENSION IS SUSPENDED IT IS MANDATORY THAT THE SHOCK ABSORBERS
REMAIN CONNECTED. FAILURE TO DO SO CAN CAUSE THE AIR SPRINGS TO EXCEED THEIR MAXIMUM
LENGTH, POSSIBLY CAUSING THE AIR SPRINGS TO SEPARATE FROM THE PISTON, OR CAUSE A
REVERSE ARCH IN THE STEEL LEAF SPRINGS, POSSIBLY RESULTING IN PREMATURE STEEL LEAF
SPRING FAILURE.

A

WARNING

REPAIRAND RECONDITIONING
THE REPAIR OR RECONDITIONING OF SUSPENSION OR AXLE COMPONENTS IS NOT ALLOWED, SEE
LABEL IN FIGURE 3-1.ANY AXLE COMPONENTS FOUND TO BE DAMAGED OR OUT OF SPECIFICATIONS
MUST BE REPLACED.ALL MAJOR HENDRICKSON COMPONENTS ARE HEATTREATED AND TEMPERED.
AIRTEK COMPONENTS CANNOT BE BENT, WELDED, HEATED, OR REPAIRED WITHOUT REDUCING THE
STRENGTH OR LIFE OF THE COMPONENT. FAILURE TO FOLLOW THESE GUIDELINES CAN CAUSE LOSS
OF VEHICLE CONTROL, POSSIBLE PERSONAL INJURY, DEATH, OR PROPERTY DAMAGE AND WILL VOID
APPLICABLE WARRANTIES.
