Do you need Roof Bars?

You'll need some roof bars to fit these boxes. We recommend you order these directly from your vehicles manufacturer.

Craving adventures but your car lacks those coveted roof rails? Fear not, wanderlust warriors! Installing a roof rack on a bare roof is perfectly achievable with the right knowledge and tools. This detailed guide will equip you with the know-how to transform your roof into a versatile cargo carrier, ready for kayaks, bikes, luggage, and all your outdoor gear.

Preparing for Takeoff:

Before you dive into installation, gather your essentials:

  • Roof rack kit: Choose a kit designed for cars without rails. Popular options include door-mounted, clamp-on, and inflatable systems. Each offers unique advantages and compatibility specifics, so research carefully.
  • Tools: You'll likely need screwdrivers, wrenches, tape measures, and a level. Some kits require additional tools, so check the instructions.
  • Cleaning supplies: Remove dirt, dust, and wax from your roof to ensure proper adhesion.
  • Patience and a sense of adventure!

Choosing Your Path:

The installation method depends on your chosen roof rack type:

Door-Mounted Systems:

  • Pros: Secure, stable, often compatible with a wide range of vehicles.
  • Cons: Requires accessing interior door panels, might not work with sunroofs.
  • Steps:
    • Follow the kit instructions to remove interior door panel trim pieces.
    • Secure mounting plates within the door frame using pre-existing bolts or provided hardware.
    • Reinstall door panel trim, ensuring no interference with opening/closing.
    • Attach the roof rack crossbars to the mounted plates on the car roof.

Clamp-On Systems:

  • Pros: Easy to install and remove, generally budget-friendly.
  • Cons: May not be as secure as door-mounted systems, weight capacity might be lower.
  • Steps:
    • Locate designated clamping points on your car's roof frame (consult the kit instructions for specific locations).
    • Position the clamp bases and tighten them securely, following the torque specifications provided.
    • Attach the roof rack crossbars to the mounted clamps.

Inflatable Systems:

  • Pros: Lightweight, portable, and easy to store.
  • Cons: Lower weight capacity, might require regular inflation, not suitable for all roof shapes.
  • Steps:
    • Locate the designated anchor points on your car's roof frame as per the kit instructions.
    • Secure the inflatable pads to the anchor points and inflate them to the recommended pressure.
    • Attach the roof rack crossbars to the inflated pads.

Landing a Smooth Installation:

Here are some helpful tips for a successful roof rack installation:

  • Read the instructions carefully! Each kit has specific nuances, so following the manufacturer's guidelines is crucial.
  • Enlist a friend! Having an extra pair of hands can make the process easier and faster.
  • Work in a well-lit area with comfortable space.
  • Double-check all connections and tighten bolts to the specified torque.
  • Test the roof rack's stability before loading it with cargo.

Beyond the Basic Climb:

Remember, installing a roof rack is just the beginning of your cargo-carrying adventures. Here are some additional points to consider:

  • Weight capacity: Ensure your chosen roof rack and your car's roof can handle the intended load safely.
  • Securing your cargo: Invest in proper straps, tie-downs, and nets to secure your gear properly.
  • Aerodynamics: Roof racks can increase wind resistance and decrease fuel efficiency. Drive cautiously and adjust your speed accordingly.
  • Regular maintenance: Check your roof rack and mounting points periodically for any signs of wear or damage.

So, gear up, embrace the DIY spirit, and conquer the bare roof! With careful planning and this guide as your compass, you'll be ready to transform your car into a versatile adventure companion, ready to carry you and your dreams to any destination.
