READ ALL INSTRUCTIONS THOROUGHLY FROM START TO FINISH BEFORE BEGINNING
INSTALLATION

IMPORTANT NOTES!

A.

 

The vehicle’s alignment must be within factory
specifications before installing this system.  Have
the alignment checked at a state approved facility.

 

B.

 

Check the frame of the vehicle for any damage or
severe corrosion.  If there is any structural damage,
Do Not install this system

 

C.

 

Do not install a body lift kit with Rancho’s
suspension system or interchange parts from this
system with components from another
manufacturer.  Use the appropriate Rancho shock
absorbers.  Contact your local Rancho
representative for the correct application.

 

D.

 

Compare the contents of this system with the parts
list in these instructions.  If any parts are missing,
including fasteners, contact the Rancho Technical
Department at 1-800-5SHOCKS.  Each hardware kit
in this system contains fasteners of high strength
and specific size.  Do not substitute a fastener of

lesser strength or mix one hardware kit with
another.

 

E.

 

Apply THREAD LOCKING COMPOUND to all
bolts during installation.  One drop on the exposed
threads of each bolt before installing the nut is
sufficient to provide an adequate bond.  CAUTION:
Thread locking compound may irritate sensitive
skin.  Read warning label on container before use.

 

F.

 

Install all nuts and bolts with a flat washer.  When
both SAE (small OD) and USS (large OD) washers
are used in a fastener assembly, place the USS
washer against the slotted hole and the SAE washer
against the round hole.
