2025+ 6th Gen 4Runner Air Dam Removal: Step-by-Step Guide

The 6th Gen Toyota 4Runner has officially hit the trails, and while the redesign is a massive leap forward, many owners are asking one question: "How do I get rid of that plastic chin?"

That "chin" is the factory air dam. While it helps highway aerodynamics, it’s usually the first thing to scrape when you're out on a trail or even on a steep driveway. In this guide, we’ll explain how to remove the 6th Gen 4Runner air dam in under 10 minutes.

Why Remove the 6th Gen Air Dam?

• Better Approach Angle: Gain significant front-end clearance to avoid that "plastic hitting dirt" sound.
• Aggressive Stance: Exposes the front tires and suspension for a rugged, squared-off look.
• Fully Reversible: If you have a long road trip planned, you can bolt it back on in minutes
• The MPG Factor: Early testing shows a negligible impact (roughly 0.3 - 0.7 MPG loss) - a trade-off that most owners are happy to make for the improved look.

Tools Required

To do this job safely without stripping the factory hardware, you’ll need:

• 10mm Deep Socket and Ratchet: We recommend this Metric Deep Socket Set - the "deep" design is crucial for reaching the tucked-away corner bolts on the 6th Gen.
• Small Flathead Screwdriver: Or a plastic trim removal tool for the retaining clips.
  
• Painter’s Tape (Optional): To protect your bumper paint while pulling the dam away
  
  

Step-by-Step Removal Guide

Step 1: Locate the Hardware

Crawl under the front bumper. You will find a total of 9 bolts (10mm) and 2 plastic "snap" clips holding the assembly to the lower bumper.

5 Bolts are along the front edge.

4 Bolts are tucked into the inner corners (2 on each side).

Step 2: Unbolt the Air Dam

Using your 10mm socket, remove the hardware.

Pro-Tip: Remove the 4 corner bolts first, then the front edge bolts. This prevents the air dam from sagging or putting stress on the plastic clips while you work.

Step 3: Pop the Retaining Clips

Once the bolts are out, the dam is held by two plastic clips near the outer ends. Give the air dam a firm, steady pull downward. They should pop right out with a little bit of force.

Step 4: Secure Your Hardware

Don't throw those bolts in a drawer! Once the air dam is off, thread the nine 10mm bolts back into their original holes in the bumper. This keeps the internal trim secure, prevents vibrations, and ensures you won't lose the hardware.

Frequently Asked Questions (FAQ)

Does this cause a "whistling" noise?

The short answer is, it can.
If you do notice a high-pitched hum after removing your air dam, don't worry, you didn't break anything. It’s just air catching the open holes in your lower control arms. You can snap in OEM Toyota Plugs or use Heavy-Duty Rubber Grommets (the budget-friendly fix) to silence the noise instantly

Does it affect Toyota Safety Sense (TSS)?

No. The TSS sensors and radar are located in the upper grille and emblem. Removing the lower air dam has zero impact on your safety systems.

What should I do next?

With the air dam gone, your factory skid plate is now front-and-center. If you're looking to swap that composite "felt" cover for real steel or aluminum protection, check out our 4Runner Deals Page for our top-vetted recommendations.
