Installation

1.  Select the LH Rocker Splitter. The LH and RH Rocker Splitters are marked on the 
back side near the center of the part. Refer to figure 1. 

2.  With an assistant, hold the left rocker splitter in position and visually note where 
the foam tape is to adhere to the factory rocker panel molding. Refer to figure 2. 
Remove the rocker splitter. 

3.  Clean the noted area and apply the 3M 4298 Adhesion Promoter to the factory 
rocker panel molding. 

4.  Using a pair of pliers, reach into the rocker panel molding pockets as shown and 
pull the (8) push pins from the left side rocker panel molding and discard. Refer 
to figure 3. The rocker panel molding will remain in place with the upper fasteners 
retaining it to the body. 

5.  Prepare the rocker splitter for installation by bending and creasing the tape pull 
tabs as shown in figure 4. Do not expose or touch the foam tape. 

6.  Loosely install the left side rocker splitter and eight (8) new push pins. Ensure 
that the foam tape pull tabs are accessible. Refer to figure 5. The picture shows a 
large gap for clarity. Press the push pins in, leaving a 1/8” to 1/4” gap.

7.  Starting at the front and ensuring that the factory rocker panel molding is nested 
into the recessed feature in the rocker splitter (refer to figure 6), fully insert the 
eight (8) push pins. The handle of a screw driver works well to fully press the 
push pins in. 

8.  Pull the four (4) tape pull tabs to remove the tape backing. Refer to figure 7.

9.  Press the left side rocker splitter into place. Apply firm pressure at 3-4 inch 
intervals along the entire length of the rocker splitter to ensure a strong bond.

 
10. Using the installed left side rocker splitter as a template, drill five (5) ¼” holes into 
the factory rocker panel molding as shown in figure 8. 

Assembly Tip: Place serveral wraps of electrical tape 1” from the tip of the drill 
bit to act as a drill stop. Refer to figure 8. 

11. Install a new push pin into each of the five (5) drilled holes. Refer to figure 9.

12. Repeat steps 1-11 for the right side rocker splitter. 

Congratulations! You have completed the installation of the Side Rocker Splitters.
