ICI STEP INSTALLATION

Step 1 (Prep)

Beginning on the Driver's side, 

remove any steps if equipped. 

Next, locate the 3 sets of 

mounting points on the 

underside of the vehicle (Fig. 1).  

Please note that your vehicle 

may have tape, plugs, and/or 

factory bolts covering up the 

mounting locations. These will 

need to be 

removed so that the 

mounting locations can be 

accessed.  Keep any OE 

hardware to reuse during 

installation.

Step 3 (Hang bar 

on Brackets)

Next, locate the driver side bar 

(100525), the distance from the 

front of the bar to the first step 

hoop is greater than the 

distance from the rear of the 

bar to the second step hoop, 

reference the diagram on page 

3. The top of the bar has a

small lip, use the lip to hang the

bar on the brackets.  This will

make the installation process

easier and hands-free.
