Why this product

Why the Thule Force XT XL?

The Force XT XL delivers 18 cu ft at just 37 lbs — that's significantly lighter than the Motion 3 XL at the same capacity. Central locking and 165 lb capacity cover the essentials. Here's the thing: if weight matters more than dual-side opening, this is a smarter buy. The downside? Single-side opening only, and the Force XT line lacks the Motion's premium fit and finish.

Frequently Asked Questions

The Thule Force XT XL uses a universal crossbar mount that clamps onto most factory and aftermarket roof racks. Check your specific vehicle in our compatibility checker below.

The Thule Force XT XL is rated for 165 lbs. But your roof's dynamic load limit is the real ceiling — most vehicles cap at 150-200 lbs including the box weight. Check your manual.

You'll hear a low hum above 65 mph — typical for roof boxes. The aerodynamic shape keeps it manageable. Proper crossbar spacing helps too.

Yes, but it's easier with two people. The box is bulky — lifting it onto the roof solo is the hardest part. Mounting hardware takes 20-30 minutes.

Yes. The hard shell keeps everything dry. ABS plastic is inherently waterproof — sealed seams and weather stripping handle heavy rain and car washes. Won't rust or corrode either.

You can, but don't. An empty roof box adds drag and hurts fuel economy by 10-25%. It also lowers garage clearance. Remove it between trips. Most boxes mount/dismount in 15-20 minutes.

Expect a 10-25% fuel economy hit at highway speeds when loaded. The aerodynamic shape helps versus an open basket, but physics is physics. Remove it between trips. That's free money back in your tank.
