How to Install a Roof Rack

The suggestions in this article are generic in nature and are not intended to replace instructions for your individual vehicle. Before undertaking repairs, please reference your owner’s handbook or repair guide.

Each kit’s installation changes differently depending on the model chosen and the manufacturer. In general, mounting your new roof rack is simple.

Cleanup Your Car’s Roof

Putting a rack on a dirty roof may make it more difficult to clean in the future and may also prohibit the rack’s connection points from resting flush.

Screws should be loosened.

Roof racks typically have two crossbars and four-foot mounts that hook to the car’s guttering or side rails. Unscrew the hand screws on the outside of the foot mounts just enough to allow them to open.

Adjust the Crossbars

Separate the foot mount apertures sufficiently to accommodate the crossbars, then place the crossbars between the four mountings. We should then have two crossbars having loosely attached foot mounts on each ends.

Measure from the inner edge of the foot mounts to determine the right width between mounts for your vehicle. Tighten the adjustments into position after the crossbar distance across mounts is the right length.

Repair the Pads and Caps

Attach the pads to the mounts and the caps to the crossbars. Roof rack pads protect your roof from scratches, and crossbar caps cover the ends of the crossbars to keep water out.

Place the Rack

Open your car’s doors and center the rack on the roof, ensuring that the front rack is properly positioned away from the top of the windshield by following the manufacturer’s safety requirements supplied with the equipment.

Secure the Rack

The accompanying metal clips connect into the underneath rim of your doors and windows and tighten them to secure the front foot mounts in place. Our crossbars and foot mounts are now securely fastened and ready for use.

Final Recommendations

Clamps can be attached to the vehicle’s current roof rack or to the door frame. Installation is determined by the make and model of your vehicle as well as the type of roof rack clamps you purchase. Read the handbook thoroughly. Many roof rack clamps even provide training videos.

FAQs About Roof Rack Clamps

What effect does a roof rack have on handling?

A big load on our roof rack reduces the vehicle’s stability since it shifts the center of gravity away. If we change direction while driving at high speeds, our car and load may become unstable, and we may lose control.

Do roof racks cause harm to your vehicle?

A properly installed and used roof rack will not do any damage to your vehicle. On the other hand, an overtightened, under tightened, improperly fitting, or overloaded roof rack might cause harm to your vehicle.

What is the ideal distance between roof racks?

Roof racks are typically spaced about 700mm apart. Any wider apart, and our load may come into contact with the ceiling between the bars. The accessories required will be determined by the sort of load to be carried.

Should I take the roof rack off while not in use?

Yes. A roof rack increases the vehicle’s wind resistance, which increases fuel usage. When not in use, be sure to take it out.

Roof racks create a lot of noise, don’t they?

A whistling, loud roof rack may be quite inconvenient, especially on lengthy journeys. This whistling is produced by high-speed wind striking the roof rack and maybe readily be remedied in a number of ways.
