PROCEDURE

1. Remove contents from box, verify if all parts listed are present and free from damage.

Carefully read and understand all instructions before attempting installation.

Failure to identify damage before installation could lead to a rejection of any claim.

2. Start the installation under the driver side of the vehicle. For Extended and Double Cab: Locate the 4 tabs along the bottom

edge of the body, (pinch weld). Mounting Brackets will bolt to the 1st, 2nd, (just in front of center of cab), and 4th mount-

ing tabs, (Figure 1A). For Crew Cab: Locate the 5 tabs along the bottom edge of the body, (pinch weld). Mounting

Brackets will bolt to the 1st, 2nd, (just in front of center of cab), and 5th mounting tabs, (Figure 1B).

Directly above each tab is a top mounting location on the side of the body panel. Hold a Bracket up in place to help deter-

mine the mounting holes to use along the body.

Assistance is recommended. On models with DEF tank, select a flat, level area for installation. May require cutting.
