SECTION 2

Product Description
ULTIMAAX is an advanced severe-duty rear rubber suspension designed specifically for fire and
rescue applications to balance outstanding durability, empty ride quality, loaded stability and
mobility. Through its unique design, the system offers premium ride quality in both empty and
loaded conditions, with increasing stability as the load increases.
■■ Equalizing beam — Formed and robotically welded to provide a narrow profile for weight

savings. Distributes load equally between axles to improve maneuverability, stability and
handling. Increases ground clearance with flat bottom design. Lowers the center of gravity to
increase stability.

■■ Saddle — Triangular geometry provides structure and durability. Weight efficient design

helps to increase payload, while offering a considerable weight savings versus competitive
suspensions.

■■ Frame hangers — Optimized design to balance durability and weight savings. Fabricated to

offer flexibility with multiple truck configurations.

■■ Rubber shear springs — Primary springs in unloaded condition, providing superb ride quality.

React to longitudinal loads during braking and accelerating for minimal displacement.

■■ Progressive load springs — Designed to balance empty ride quality and loaded stability.

Stiffness of progressive load spring increases as load increases, providing a unique balance
of empty ride quality and loaded stability.

■■ Longitudinal torque rods — Engineered to optimize resistance to axle wind-up during accel-

eration and braking.

■■ Transverse torque rods — Heavy‑duty transverse torque rods ensure maximum lateral axle



control and straight line suspension stability.

SAFETY PRECAUTIONS

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, ADVERSE VEHICLE HANDLING,
PERSONAL INJURY, OR PROPERTY DAMAGE.
LOOSE OR OVER TORQUED FASTENERS CAN CAUSE COMPONENT DAMAGE, ADVERSE VEHICLE
HANDLING, 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
HENDRICKSONeBay logo SUPPLIED FASTENERS ONLY. IF NON-HENDRICKSONeBay logo FASTENERS ARE USED, FOLLOW
TORQUE SPECIFICATION LISTED IN THE VEHICLE MANUFACTURER’S SERVICE MANUAL.

TORCH/WELDING
DO NOT USE A CUTTING TORCH TO REMOVE ANY FASTENERS OR BUSHINGS. THE USE OF HEAT
ON SUSPENSION COMPONENTS WILL ADVERSELY AFFECT THE STRENGTH OF THESE PARTS. A
COMPONENT DAMAGED IN THIS MANNER CAN RESULT IN THE ADVERSE VEHICLE HANDLING AND
POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE.
EXERCISE EXTREME CARE WHEN HANDLING OR PERFORMING MAINTENANCE IN THE AREA OF THE
EQUALIZING BEAM. DO NOT CONNECT ARC WELDING GROUND LINE TO THE EQUALIZING BEAM. DO
NOT STRIKE AN ARC WITH THE ELECTRODE ON THE EQUALIZING BEAM AND AXLE. DO NOT USE HEAT
NEAR THE EQUALIZING BEAM ASSEMBLY. DO NOT NICK OR GOUGE THE EQUALIZING BEAM. SUCH
IMPROPER ACTIONS CAN DAMAGE THE EQUALIZING BEAM ASSEMBLY AND CAUSE ADVERSE VEHICLE
HANDLING AND POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE.

LOAD CAPACITY
ADHERE TO THE PUBLISHED CAPACITY RATINGS FOR THE SUSPENSION. ADD-ON AXLE ATTACHMENTS
AND OTHER LOAD TRANSFERRING DEVICES CAN INCREASE THE SUSPENSION LOAD ABOVE ITS RATED
AND APPROVED CAPACITIES, WHICH CAN RESULT IN COMPONENT DAMAGE AND ADVERSE VEHICLE
HANDLING, POSSIBLY CAUSING PERSONAL INJURY OR PROPERTY DAMAGE.

MODIFYING COMPONENTS
DO NOT MODIFY OR REWORK PARTS WITHOUT AUTHORIZATION FROM HENDRICKSONeBay logo. DO NOT
USE SUBSTITUTE OR REPLACEMENT COMPONENTS NOT AUTHORIZED BY HENDRICKSONeBay logo. USE OF
MODIFIED, REWORKED, SUBSTITUTE OR REPLACEMENT PARTS NOT AUTHORIZED BY HENDRICKSONeBay logo
MAY NOT MEET HENDRICKSONeBay logo’S SPECIFICATIONS, AND CAN RESULT IN FAILURE OF THE PART,
ADVERSE VEHICLE HANDLING, AND POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE AND WILL
VOID WARRANTY. USE ONLY HENDRICKSONeBay logo AUTHORIZED REPLACEMENT PARTS.

PERSONAL PROTECTIVE EQUIPMENT
ALWAYS WEAR PROPER EYE PROTECTION AND OTHER REQUIRED PERSONAL PROTECTIVE EQUIPMENT
TO HELP PREVENT PERSONAL INJURY WHEN PERFORMING VEHICLE MAINTENANCE, REPAIR OR
SERVICE.

PROCEDURES AND TOOLS
A TECHNICIAN USING A SERVICE PROCEDURE OR TOOL WHICH HAS NOT BEEN RECOMMENDED BY
HENDRICKSONeBay logo 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.

SADDLE CONNECTION
A SADDLE ASSEMBLY IS ATTACHED TO THE CENTER BUSHING OF EACH EQUALIZING BEAM WITH TWO
(2) SADDLE CAPS. EACH SADDLE CAP USES TWO (2) BOLTS TO CLAMP THE CENTER BUSHING INNER
METAL TO THE SADDLE. EACH SADDLE CAP MUST BE INSTALLED SO THAT THERE IS AN EVEN GAP
BETWEEN THE SADDLE CAP AND THE BASE OF THE SADDLE LEGS AS SHOWN IN FIGURE 3-2. IF EACH
SADDLE CAP IS NOT INSTALLED EVENLY, THE SADDLE LEGS COULD BECOME DEFORMED, RESULTING
IN BENT BOLTS OR DAMAGED SADDLES.
