The Lexus GX is an amazing SUV and it offers a very spacious interior. However, the 11.6 cubic feet trunk space behind the rear seats is hardly enough to meet all your storage needs.
As such, you might want to complement it with a roof box. A roof box will ensure you can haul your gear/cargo conveniently and securely.
We’ve thoroughly scraped the market to provide you with a comprehensive shortlist of the best roof boxes for your Lexus GX.

Thule Motion XT Rooftop Cargo Carrier
The Motion XT is a durable extra-large cargo carrier that comfortably accommodates camping gear and luggage for up to 5 travelers. It is massive (91.5 x 37.5 x 18 inches) and it offers 22 cubic feet or 165 pounds of additional storage for your Lexus GX.
The gigantic size won’t be a problem when driving as the carrier’s aerodynamic shape is designed to cut down wind resistance and noise for a smooth drive and better MPG. As with most premium roof boxes, it opens from both sides and has universal rack compatibility.
It can be easily mounted thanks to the PowerClick mount system but find an extra pair of hands to aid in the lifting of the 55-pound carrier onto your vehicle’s roof. The SlideLock, unique to the Motion XT carriers, offers enhanced security to your belongings with its separate opening and closing functions.
Malone Profile18S Rooftop Box
Are you looking for a stylish and spacious heavy duty roof box? Look no further than Malone Profile18S. Made in Italy from industrial grade ABS plastic certified to be UV and abrasion-resistant, it will offer protection from all the weather elements.
The Malone Profile18S weighs the same as the Motion XT but has a lesser 18 cubic feet capacity mainly attributable to the smaller frame or dimensions. The pearl silver textured finish rounds off the elegant construction of the carrier.
The roof box comes with a centralized locking system for secure lid closure and easy access from either side of your SUV. No assembly and tool-free mounting make it relatively quick to install the roof box. The carrier delivers just as much as the Thule, and if you’re on a budget, the Malone Profile18S is a great pick.
Thule Force XT Rooftop Cargo Box
With humongous 22 cubic feet of cargo space, the Force XT is Thule’s second carrier on our list and boasts of the same 165-pound load capacity. If you always have onboard long and awkwardly-shaped gear such as surfboards and kayaks, this box was made for you.
At 90.5 inches long and 35.5 inches wide, the Force XT packs in up to 7 pairs of skis with a maximum length of 215cm. Besides functionality, the carrier has an amazing glossy exterior finishing for a stunning modern outlook.
The LockKnob system replaces the Motion XT’s SlideLock, offering slightly better performance and protecting the Thule Comfort Key. The mounting dial emits a click sound once the box is appropriately mounted.
This ensures that you will always mount your roof box securely. Additionally, it is built to sit forward on the crossbars providing you with full access to the rear hatch.
SportRack Vista XL Cargo Box
The SportRack Vista’s frame is constructed from high-density ABS plastic to provide you with a durable yet lightweight (28 pounds) cargo box. Angled contours and a streamlined shape dissipate the whistling sounds and ensure you don’t have to spend more on gas.
The carrier boasts 18 cubic feet of storage space with the load limit capped at 100 pounds. The fascinating feature of the Vista has to be the unorthodox rear lid opening. If you’re not endowed with 6’ height, it’s pretty hard to reach the rooftop of your Lexus GX without sourcing for a stand.
However, you can use the rear bumper as an elevation to conveniently access your gear. In addition, it has sturdy lid stiffeners that keep the box open when loading or unloading.
JEGS Rooftop Cargo Carrier
At first glance, you will be forgiven to think that the JEGS carrier doesn’t hold as much gear, unlike other boxes in this article. It is the smallest in terms of size, 57.5 x 13.75 x 38.5 inches, however, it has an impressive 18 cubic feet of additional cargo space.
Molded from 4-season HDPE plastic for tough and durable construction, the carrier is designed to be fit on cross rails systems rated no less than 150 pounds and always has to be mounted on a rack. A front latch ensures that the lid does not pop open due to airflow created when driving at high speeds.
Moreover, it is combined with the four corner locking system for the ultimate security of your belongings. Easy mounting, dual-side opening, and low price further enhance its claim of being one of the best roof boxes for your Lexus GX.
Most of the featured carriers also require a roof rack system. As much as they are relatively inexpensive, strictly adhere to compatibility with your Lexus and roof box for the perfect installation. Lastly, whichever product you pick, you can be guaranteed that it will perfectly fit on Lexus GX.
