INSTALLATION INSTRUCTIONS

Congratulations – your new Work-Rite load assists are quality products
capable of improving the handling and comfort of your vehicle while under load. As
with all products, proper installation is the key to obtaining all of the benefits your
kit is capable of delivering. Please take a few minutes to read through the
instructions to identify the components and learn where and how they are used. It
is a good idea to start by comparing the parts in your kit with the parts list below.

NOTE: IF ANY PARTS ARE MISSING FROM THE KIT,

PLEASE CALL 1-800-888-0650.

PLEASE DO NOT CALL OR RETURN THE KIT TO THE DEALER.

Be sure to take all applicable safety precautions during the installation of the
kit. The instructions listed in this brochure and the illustrations all show the left,
or driver’s side of the vehicle. To install the right side assembly simple follow the
same procedures.

STEP 1 – PREPARE THE VEHICLE

With the vehicle on a solid, level surface chock the front wheels. Remove the
negative battery cable. Remove the jounce bumpers located under the frame rail,
by prying them out of the jouncer bumper cup. The jounce bumpers will not be
re-used with this kit.

STEP 2 – PRE-ASSEMBLE THE KIT

Insert the two of the upper inserts into the bumper cup above the retaining
tabs. Next, insert a carriage bolt into the lower insert. The 1.5" carriage bolt will
be used without a spacer and the 2" carriage bolt will be used with the spacer. Fasten
the lower insert to the upper inserts using two 3/8"-16 x 1" hex head bolts. Place
the bumper cup plate on top of the Work-Rite load assist bumper and then fasten
to the carriage bolt using the large 3/8" washer and the 3/8"-16 flange nut.

NOTE: An optional spacer may be installed to engage the Work-Rite sooner
when a load is applied. To install, place between the Work-Rite and the plate.
If the spacers are installed, use the 3/8"-16 x 2" bolts instead of the 3/8"-16
x 1-1/2" bolts. There should be 1/4" to 3/8" between the Work-Rite and the
axle. See Figure “B”.

STEP 3 – FINISH UP

Remove the wheel chocks and reconnect the battery cable. Now you're finished
and ready to put your Work-Rite to use!

FIRESTONE LIMITED LIFETIME AIR SPRING WARRANTY

Firestone Industrial Products Company LLC (“Firestone”) warrants that its Ride Rite Air Spring Assembly will perform

according to the manufacturer’s specifications for as long as the vehicle on which the system was originally installed

is owned by the original retail purchaser. This limited warranty does not include installation or other service charges

for replacement.

Warranty Period

The Air Spring is warranted for as long as the original purchaser owns the vehicle on which it was originally

installed. The fasteners and upper and lower brackets which accompany the air spring are warranted for a period

of twenty-four (24) months or 24,000 miles whichever occurs first. This warranty begins on the original retail

delivery date.

What is Covered

Any implied warranties are limited in duration to the coverage period of this warranty (some states do not allow

limitation on how long an implied warranty lasts so the above limitation may not apply to you). This Warranty runs

in favor of the original retail purchaser when the Ride Rite Air Spring Assembly is used under normal operating

conditions according to Firestone’s specifications and installed on the appropriate application. This warranty does not

apply to Ride Rite Air Spring Assemblies that have been improperly applied, improperly installed, used in racing or off

road applications or used for commercial purposes. In addition, the warranty will not apply to products which have

not been maintained and serviced according to the instructions that accompany the air spring assembly. The

consumer will be responsible for any costs incurred in removing the product from the vehicle and the cost to return

the air spring assembly to the dealer or installer from which it was purchased. If it is determined that the Ride Rite

Air Spring Assembly failed as a result of a manufacturing defect, Firestone will repair or replace, at its option, any

product or components subject to this warranty. You should retain a copy of your contract with your installer and

your receipt as proof of the date of installation. This warranty is non-transferable and is not assignable in any way.

Firestone specifically excludes any obligation for consequential damages or incidental expenses including claims for loss of use of

the product, loss of time, inconvenience, or commercial loss. This warranty gives you specific legal rights. You may also have other

rights that may vary from state-to-state. Some states do not allow limitations on how long an implied warranty lasts or allow the

exclusion or limitation of incidental or consequential damages. The above limitation or exclusion may not apply to you. There are

no warranties, express or implied, including implied warranty of merchantability and fitness which extend beyond this warranty.
