Installation Instructions

Follow these steps carefully for proper installation. It is recommended to have a second person assist with positioning the running boards.

Step 1: Prepare the Vehicle

Park the vehicle on a flat, stable surface. Engage the parking brake. Locate the factory mounting points along the rocker panel or frame of your truck. These are typically pre-drilled holes or existing bolts.

Step 2: Identify Mounting Brackets

Identify the correct mounting brackets for the driver's side and passenger's side. Brackets are often labeled "D" for driver and "P" for passenger, or "F" (front), "M" (middle), "R" (rear).

Step 3: Install Mounting Brackets

Attach the brackets to the vehicle's frame or rocker panel using the provided hardware. Hand-tighten all bolts initially. Do not fully tighten until all brackets are in place and the running board is aligned.

Step 4: Trimming Undercarriage Cover (If Required)

Important Note:

For most vehicles, trimming of the undercarriage cover is required to allow proper fitment of the mounting brackets and running boards. Carefully identify the areas of the undercarriage cover that obstruct the bracket installation. Use a utility knife or trim tool to make precise cuts. Ensure cuts are clean and minimal to maintain the integrity of the cover.

Step 5: Attach Running Boards to Brackets

Carefully position the running board onto the installed brackets. Align the pre-drilled holes on the running board with the holes on the brackets. Secure the running board to the brackets using the remaining hardware. Hand-tighten all fasteners.

Step 6: Adjust and Final Tighten

Adjust the running boards for optimal alignment and desired position. Once satisfied with the alignment, fully tighten all bolts to the manufacturer's recommended torque specifications (if available). Double-check all fasteners to ensure they are secure.

Step 7: Post-Installation Check

After installation, drive the vehicle for a short distance and then re-check all fasteners for tightness. Re-tighten if necessary. Periodically check fasteners for tightness during regular vehicle maintenance.

Operation

VANGUARD CB3 Running Boards provide a stable step for easier entry and exit from your vehicle. Ensure your footing is secure when using the running boards, especially in wet or icy conditions. The textured surface is designed to enhance grip.

Maintenance

• Cleaning: Clean the running boards regularly with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the powder coat finish. Rinse thoroughly and dry with a soft cloth.
• Inspection: Periodically inspect the running boards and all mounting hardware for any signs of wear, damage, or looseness. Tighten any loose fasteners immediately.
• Corrosion Prevention: The electrophoretic black primer combined with a black powder topcoat provides excellent corrosion resistance. However, regular cleaning and inspection will help maintain its appearance and longevity, especially in areas exposed to road salt or harsh weather.

Troubleshooting

• Running Board Feels Loose: Re-check all mounting bolts and nuts. Ensure they are tightened to the correct specifications. Inspect brackets for any damage or bending.
• Difficulty Aligning: Ensure you have the correct brackets for each position (front, middle, rear) and side (driver, passenger). Loosen all fasteners slightly to allow for adjustment, then re-tighten once aligned.
• Noise/Rattling: Check all contact points between the running board, brackets, and vehicle frame. Ensure no components are rubbing. Verify all hardware is securely fastened.
