Thule Force 3 Cargo Box hauls gear with rugged style and streamlined performance
What Our Gearhead® Experts Are Saying:
“I’ve used the Thule Force 3 on cross-country ski trips, summer road vacations, and even grocery hauls when we needed extra cargo space. The quick PowerClick mount makes setup so easy—even solo—and the DualSide access is a lifesaver when you're parked tight or packing late at night. It's solid, quiet, and fits everything from snowboards to duffels.”
From weekend mountain escapes to long-haul road trips, the Thule Force 3 Cargo Box transforms our vehicle into an all-season hauler. Built with a rugged AeroSkin surface, it stands up to heavy use and harsh weather, while its clean lines and aerodynamic profile help reduce drag and wind noise along the way. Whether we're loading skis for winter laps or stashing camping gear for the desert, the Force 3 gives us the added space we need without compromising on style or efficiency.
We especially love the practical design that keeps up with fast-paced travel. The PowerClick mounting system makes attachment fast and intuitive, with an integrated torque indicator that clicks into place when it’s secure. DualSide opening adds flexible access from either side of the vehicle, and the SlideLock system makes sure the lid stays locked and sealed with an audible confirmation. With room for up to seven pairs of skis or five snowboards, this box is ready for whatever adventure we're chasing next.

Easy attachment, tons of room.
[This review was collected as part of a promotion.] Going from an old beat up box to this has been a dream. The fact that it opens from boths sides is absolutely crucial for me, as my car has limited access on the normal passenger side of things. The key and latch system is so easy to open and close, whereas my last box always required a wrestling match to get closed.

The perfect addition to any vehicle!
[This review was collected as part of a promotion.] The Thule Force 3 is the perfect addition to our Toyota 4Runner! The delivery was fast, and the installation was a breeze. The trickiest part for me was positioning the box just right—I prefer to have it centered on the roof, as we often access gear from both sides depending on the situation. The XL size is a great fit for an SUV. Due to the design of our crossbars, we did need to shift the box back a bit further than we initially wanted, which prevents the trunk from opening fully. However, this is entirely our choice, and I don't fault Thule for this minor issue. We took the roof box on a skiing trip right away, and it held our 4 skis and poles with ease! It’s been a game-changer for freeing up space inside the car. While the box does make a bit of noise once we hit 70mph, it's nothing that bothers us. Overall, I highly recommend the Thule Force 3 to anyone in need of extra storage. We're thrilled to have it as part of our gear setup!

Easy to install
[This review was collected as part of a promotion.] The Thule Force 3 was quick and easy to mount, and I love the dual side entry which makes it convenient to access gear from either side of the vehicle. The box seems very durable, and I love the sleek, aerodynamic shape of it. In addition to the shape of the box acting as a natural handle to open and close the box, there is a pull cord to help easily pull the box closed. The locking system makes it easy to lock with a sliding mechanism, and it clearly clicks when it is securely closed.
