Bare roof systems

Gutter systems

This roof style sees a gutter running along the edge of the roof. This type is most often found in vehicles such as Jeeps. These systems require universal roof bars for cars equipped with unique feet that block the gutter slide and fix on them. This style of roof system is outdated and not often found in modern cars.

Raised rails

These vehicles come with pre-installed roof rails that function as roof racks themselves. Crossbars with unique feet that bolt into these raised rails. Another Jeep roof rack is the perfect example, this time for the Jeep Grand Cherokee.

Roof capacity and universal car roof bars

The load capacity of the car is a key feature to consider. Your vehicle handbook will indicate the load rating and universal car roof bars will need to match this. If you don’t have the manual, you can always call a dealer for information or look it up on the Internet. It is essential to take this into account because overloading your vehicle can cause you to pay a hefty fine, but it also increases the risk of having an accident.

Understanding dynamic capacity, i.e. the load your car can carry on its roof as you travel down the road, is key. Each vehicle’s capability is different, making it essential to find out your car’s dynamic capability. Even if a larger capacity fits in your roof box, that doesn’t mean you should exceed the prescribed weight limit.

However, it would be helpful not to fall into the trap of confusing dynamic capacity with static capacity. Static capacity is the weight of the load that the vehicle can support when stationary. This number is often higher than the dynamic capacity. When you overload a vehicle, you may also experience handling problems. Vehicles arrive with their weight evenly distributed and close to the ground. This allows the vehicle to corner at speed without rolling over. When the load is placed on the roof of the vehicle, it moves away from the car’s center of gravity. Transferring most of the weight to the top of the vehicle when overloaded means that the vehicle loses its ability to handle corners. As a result, your vehicle could roll over. So be very careful when choosing universal roof bars for cars.
