Thule Force 3 Cargo Box

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.
