How to Install Roof Racks on Your Toyota 4Runner: Step‑by‑Step Guide

Adding a roof rack to your Toyota 4Runner is one of the best upgrades you can make for utility, storage, and adventure readiness. Whether you’re hauling a rooftop tent, kayaks, recovery boards, or extra cargo, a properly installed rack ensures you’re secure on‑road and off.

This guide walks you through the installation process and highlights a few must‑have accessories to make the most of your new rack.

Tools & Prep Work

Before diving in, make sure you’ve got the basics covered:

• Socket set

• Allen wrenches (specific sizes vary by rack brand)

• Torque wrench (to tighten hardware properly)

• Ladder or step stool (to safely reach the roof)

 Start by exploring our 4Runner Roof Racks Collection to find the rack that best suits your setup.

Step‑by‑Step Roof Rack Install

Step 1: Remove the Factory Rails

Most 4Runners come with stock rails that aren’t designed for heavy‑duty use. Remove the factory bolts and lift off the rails. Keep the hardware if you want to reinstall later.

Step 2: Clean the Mounting Surface

Before installing your new rack, wipe down the roof and check the mounting points for dirt or debris. A clean surface ensures a secure, weather‑tight seal.

Step 3: Install Mounting Brackets

Line up the supplied brackets with your factory mounting points. Use the included hardware and torque them to spec. Many racks include rubber gaskets to prevent leaks—double‑check they’re seated correctly.

Step 4: Assemble the Rack

If your rack ships in sections, assemble it on the ground first. This usually means bolting together the side rails and crossbars.

Step 5: Mount the Rack to the Roof

With a friend’s help, lift the assembled rack onto the roof brackets. Align carefully and secure with the provided hardware.

Step 6: Torque & Double‑Check

Once everything is aligned, torque all bolts to the manufacturer’s spec. Double‑check crossbars for even spacing and ensure the rack sits level.
