Thank You for Choosing
Congratulations on your purchase of high quality, steel reinforced running boards from Aero-Tec.
Aero-Tec running boards are designed and engineered to install easily, look great and provide years of dependable use and vehicle protection.
Aero-Tec

Hardware and Materials Enclosed:

  • Self-tapping Tek-head Screws
  • Black Caps and Washers for Wheel Wells
  • Die-cut Step Pads
  • Two Aero-Tec Emblems

Tools Required:

  • Screw Gun or Variable Speed Drill (with 5/16” Hex Head Drive)
  • Two Pair of Locking Pliers or Clamps

NOTE: Due to the design and the steel reinforcement, this particular style of Aero-Tec running boards requires absolutely NO SUPPORT BRACKETS to complete the installation.

Step 1.
Position the Running Board on the Rocker Panel of Your Vehicle.
(Refer to the diagram)

  • These boards are designed to mount under the rocker panel and against the vertical “pinch-weld”, if they exist on your vehicle.
  • Align the running board so that the mud flaps are flush with the outside edge of the wheel wells. Vehicles with factory wheel flares may require the mud flaps to to mounted slightly inside the wheel wells. Proper alignment is achieved when the mud flaps are flush with the wheel well and the in-step is level.

Step 2.
Clamp Running Board in Place onto Your Vehicle.

  • Using the locking pliers, clamp the mud flaps tightly into the wheel wells. Most vehicles have a wheel well lip that allows this clamping. If yours does not, assistance may be required to hold the board in this position.

Step 3.
Attach End Flaps to the Wheel Wells.

  • Using self-tapping 1” tek-head screws, drive one screw with washer through each mud flap into the metal edge of the wheel well approximately 1 1/2” from the top of the flap. Some vehicles with factory flares may require longer screws for this step. Check your kit to see if longer screws are included. Note: Attachment screws for all Aero-Tec Boards are “tek-head” self-tapping. No Pre-Drilling is Necessary!
  • Remove the clamps from the wheel wells.

Step 4.
Attach Running Board to the Rocker Panel.

  • Use the locking pliers or clamps to snug the back edge of the running board to the rocker panel.
  • Drive 1” screws from the bottom of the board into the rocker panel. The screws should be placed approximately 3/4” to 1” from the back edge of the board, but this may vary with some vehicle models. Washers are not necessary for this step.

Step 4. (Continued)
The number of screws required is determined by the length of the board. One screw every 10 to 12 inches is sufficient. Tighten only to “snug” position. DO NOT OVER-TIGHTEN.

CAUTION

The rocker panels on some vehicles contain electrical wiring and/or air conditioning lines. Before drilling, physically check for this possibility and if either exist, move them out of the way.

Step 5.
Attach Second Screw in Wheel Wells.

  • Drive second screw with washer through each mud flap into the wheel wells approximately 4” from top of flaps.

Step 6.
Beginning with Step 1., Repeat the Entire Process for the Other Side of Your Vehicle.

Step 7.
The Finishing Touches.

  • Press black caps onto washers in wheel wells.
  • Affix die-cut step pads to molded in-steps. Press firmly.
  • Apply “Aero-Tec” emblems in desired location.

Important:

After installation apply full weight pressure to the running boards throughout the step area. This will properly “seat” the screws into the fiberglass and eliminate future stress sounds.

Note: Vehicle dimensions do occasionally vary within the same model and year. Aero-Tec running boards provide ample flex to accommodate reasonable variations.

Rear Mud Flap Installation. (Refer to the diagram)
If you have purchased rear mud flaps (separate pieces that attach behind the rear wheels); additional screws and washers are provided. Installation is completed by clamping and attaching with self-tapping screws in the same fashion as the running boards.

Care and Maintenance:
Once attached to your vehicle, these running boards become a part of it and should be maintained as such. Proper care will provide years of beauty and dependability. Congratulations
