Some vehicles come with the roof rack, while some do not.

If you want to use a roof box and your vehicle does not come with a roof rack. You can install the roof rack or use the roof bag without the roof rack. Note that you can use some roof bags without using a roof rack.

How to properly install a roof rack

Before installing them on your car, you must check all parts to ensure they are not damaged or have loose nails sticking out, which can scratch your car when placed over the top.

There are different mounting systems. The one you need depends on the mounting system of your car or 4WD. About the mounting system, if you have an old 4WD or car, you should use a gutter mount system.

Step 1: Figure out your mounting system

What determines if you need any extra equipment is when you have figured out your mounting system. For example, some roof racks can be attached to ordinary roofs using crossbars, fit kits, etc.

It is best for cars with curved roofs to use a short roof adapter before your roof racks can be mounted. The adapters will help with weight distribution on both doors.

Step 2: Put the frame of the roof rack together

The next thing you should do is screw the crossbar and the side rails and then place the frame on the vehicle.

Step 3: Expose the mount holes

At this point, you need to drill holes or uncover the mount holes. The cars with naked roofs will require you to drill holes into the roof to fit the roof rack. If your vehicle has factory-issued mount holes, you will not need any drilling.

What you need to do next is to tighten the screws by inserting them through the roof rail. What this will do is to help you fix the base of the roof rack to the car.

If your vehicle has roof rails, you should look out for thumbscrews that will help you loosen the rails for their location to be altered when needed.
