IMPORTANT NOTES! 

WARNING:

    This  suspension  system  will  enhance  the  off-road

off-road, from a factory equipped passenger car or truck.  Extreme 

care  must  be  used  to  prevent  loss  of  control  or  vehicle  rollover 

during abrupt maneuvers.  Failure to drive this vehicle safely may 

result  in  serious  injury  or  death  to  the  driver  and  passengers. 

ALWAYS  WEAR  your  seat  belts,  REDUCE  your  speed,  and 

AVOID sharp turns and other abrupt maneuvers. 

A. 

Before  installing  this  system,  have  the  vehicle's  alignment 

and  frame  checked  at  a  state  approved  facility.    The  alignment 

must be within factory specifications and the frame must be sound 

(no cracks, damage, or corrosion). 

B. 

Do not install a body lift kit with Rancho’s suspension system 

or  interchange  parts  from  this  system  with  components  from 

another manufacturer.  To obtain maximum performance, use the 

following Rancho shock absorbers with this kit:  RS5255, RS9255, 

RS99255,  or  RS999255  for  the  front  &  RS5256,  RS9256, 

RS99256,  or  RS999256  for  the  rear.    OE  steering  stabilizer

strength and specific size.  Do not substitute a fastener of lesser 

strength or mix one hardware kit with another. 

D. 

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. 

E. 

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. 

F. 

Unless otherwise specified, tighten all bolts to the standard 

torque specifications listed at the end of the note's section.  Do not 

use an impact wrench to tighten any of these bolts.  They tend to 

over tighten smaller bolts and under tighten larger bolts.  USE A 

TORQUE WRENCH!!

of  components  enamel  paint  can  be  applied  over  the  original 

coating.
