Thule Evo Clamp Roof Rack Installation on a Mazda CX-9
The Mazda CX-9 is a spacious midsize SUV that’s popular for driving in Calgary and heading out for family adventures across Alberta. With a smooth roof and no raised rails, it requires a clamp-based roof rack system designed specifically for this vehicle. For this installation, our team set up a Thule Evo Clamp system paired with aerodynamic WingBar crossbars and a Thule Force 3 XXL cargo box. The result is a clean, secure setup that dramatically increases cargo capacity for road trips, skiing, and camping.
Clean, Secure Fit on the Mazda CX-9
This Mazda CX-9 features a bare roof with no factory rails or fixed mounting points. Because of this design, the rack system must connect using a vehicle-specific clamp fit kit that attaches securely to the door frame.
The Thule Evo Clamp system uses precision-fit components that match the CX-9’s roofline exactly. Once installed, the WingBar crossbars sit level and secure, providing a stable base for mounting cargo boxes and other accessories while maintaining a sleek, factory-style appearance.
What We Installed on This Mazda CX-9

Why This Rack Setup Works for Calgary Drivers
- Vehicle-specific clamp fit ensures a secure connection on bare roofs
- Large cargo box adds significant storage for family trips and ski gear
- Aerodynamic WingBar design helps reduce wind noise on highways
- Perfect for Alberta conditions including snow, long drives, and mountain travel
Important Fit Note: Bare Roof Clamp Systems
Some vehicles, including the Mazda CX-9, require a clamp-based system due to the absence of rails or fixed points. The correct fit kit depends on the exact model year and body style, and using the wrong components can affect both safety and performance.
Proper bar spacing is also critical when installing larger cargo boxes like the Thule Force 3 XXL to ensure balanced weight distribution and hatch clearance.
