Frequently Asked Questions (FAQs)

1. Are roof racks interchangeable between cars?

No, roof racks are not interchangeable between cars. Each vehicle has a unique roof profile, and roof racks need to be designed specifically to fit that particular vehicle. Factors like factory rails and rain gutters determine the type of roof rack that will be suitable for a specific car.

2. How do you install a roof rack without rails?

There are three methods to install a roof rack system on a car without rails. The first method involves using feet and clips that are compatible with the roof rack system. The second method is to use straps that go around the car roof. The third method is to use a gutter mount kit, which attaches to the car's rain gutters.

3. How do I know if my roof rack will fit my car?

To determine if a roof rack will fit your car, you can refer to your vehicle's owner manual, which usually provides information about the roof rack and load carrier capacity. If you don't have the manual, you can also find this information online.

4. Can roof racks be universal?

No, roof racks are not universal. While some components like crossbars and racks may have universal compatibility, other parts like mounts, which are used to fasten the rack to the vehicle, vary between car makes and models. It is important to choose a roof rack that is specifically designed for your car.

5. Can I mount roof racks without a track mount?

Yes, you can mount roof racks on cars without a track mount. The most common method is using clamp mounts, which are suitable for vehicles without factory provisions for fitting roof racks. These clamp mount roof racks provide a secure installation on bare roofs.

6. Can you install a roof rack on a car that doesn't have one?

Yes, even if your car doesn't have factory rails, there are still options for installing roof racks. Some vehicles, like BMW, Volkswagen, and Mazda, may come with fixed mounting points from the factory. These mounting points can be used to install roof racks on cars that don't have factory rails.
