4th Gen 4Runner Mods (2003–2009)

If you’re driving a 4th Gen 4Runner and you’re finally ready to make it more than just a stock SUV, this is where you start. Right here.

We’ve grouped together the most useful, most necessary, and frankly, most satisfying 4th Gen 4Runner mods you'll ever install. All built around the actual needs of off-roaders, overlanders, weekend warriors, or just people who can’t stand driving around in something that feels halfway done.

Let’s get into it.

1. Center Console Modular Accessory Dash Mount (MAM)

You know that junk bouncing around your cab on trails? Fix it.

The 4th Gen 4Runner Modular Accessory Dash Mount (MAM) is for anyone who’s tired of clutter, hates fumbling for gear, and wants their interior to work as hard as the rest of their build. The dash mount gives you a sturdy, customizable base to hold your phone, CB radio, walkie, or anything else you reach for during a drive.

• Built for the 4th Gen 4Runner interior

• Handles trail vibration like it’s nothing

• Installs quickly, holds strong

• Great for CBs, nav, gear you actually use

If you’re serious about modding your 4th Gen 4Runner interior, you're at step one with TEQ Offroad’s MAM. It keeps your cab tight, functional, and finally organized the way it should be. It supports the organization and functionality of your interior for efficient driving in any type of terrain.

2. Under Hood LED Light Kit for ALL MAKES and Toyotas (4Runners, Tacomas, Sequoias, Tundras, LC, FJ, GX)

You’ve probably been there: it’s pitch dark, your truck’s steaming, and your phone flashlight isn’t cutting it. That’s why the Under Hood LED Light Kit exists.

Whether you’re checking your oil, tweaking your exhaust, or loading up for a late drive out, the hood light kit lights up your engine bay like a stadium. Installing the under-hood LED light kit is straightforward and can be done in minutes.

• 1300 lumens aimed directly at your engine bay

• Rain-resistant and trail-proof

• Fits almost any Toyota (yes, your 4th Gen 4Runner included)

• Complements your vehicle's headlights for better visibility

3. Differential Breather Relocation Kit for Toyotas

Toyota put the rear differential breather right on top of the diff. It clogs with dirt. It floods if the diff cools off underwater. It builds pressure and blows out your seals. And then you’re calling a tow truck.

That’s why you need Teq Offroad's Differential Breather Relocation Kit. It moves the breather up and out of the danger zone, so water crossings stop being a gamble. The kit also protects the differential from damage.

• Choose from 6ft or 8ft lengths

• Raise it to the gas tank or even a tail light

• Avoid pressure failures and clogged breathers

• Keeps your rear differential sealed and protected

It's one of those silent upgrades. You won’t see it, you won’t hear it. But it’ll save your truck’s backend when the trail goes muddy, wet, or messy.

Built for People Who Drive Their Toyota, Not Park It

Every mod you see here was picked because it solves a real problem. Not for show. Not for flex. For function.

The 4th Gen 4Runner might not be the newest kid on the block, but with the right upgrades, it’ll outrun, outclimb, and outlast trucks half its age. TEQ Offroad builds parts that keep you moving forward, whether that’s overland trails, weekend mountain runs, or building out a rig that feels finished.

The mods are for Toyota owners who want more control, more reliability, and more satisfaction every time they turn the key.
