| How To Fit Tesla Roof Bars |
Step 1: Gather Your Arsenal (Tools and Supplies) ️
First things first, let's make sure you have everything you need. Imagine getting halfway through and realizing you're missing a crucial piece! So, lay everything out and verify you have:
Your Tesla Roof Rack Kit: This should include the front and rear crossbars, mounting pads, rail clips, anti-abrasion tape, wingnuts, a hex wrench (or torque wrench with appropriate socket), and keys for locking.
Isopropyl Alcohol (IPA) Wipes or Solution: For thoroughly cleaning the installation areas.
Clean Microfiber Cloths: To dry the surfaces.
Tape Measure: Essential for precise positioning.
Trim Tool (Plastic Pry Tool): Provided with your kit, this helps safely retract the rubber seals.
A Friend (Optional but Recommended): While possible to do alone, having an extra set of hands makes placing the crossbars much easier and safer, especially to avoid scratching your vehicle's roof.
Torque Wrench with 8mm Socket (Highly Recommended): This is crucial for tightening the wingnuts to the exact specified torque (typically 2.5-3.5 Nm or 2.6 lbs-ft for Model 3/Y), preventing damage to your glass roof from over-tightening. If you don't have one, consider borrowing or investing in one for this project.
Personal Protective Equipment (PPE): Safety glasses and gloves are always a good idea.
The Installation Process: A Step-by-Step Walkthrough
Now that you're well-equipped, let's dive into the installation. Precision and patience are your best friends here.
Step 2: Clean and Protect Your Pristine Roof ✨
This step is crucial for both adhesion of the anti-abrasion tape and preventing any scratching of your car's finish.
2.1 Spotting the Markers: Arrows on the Glass
Your Tesla's glass roof has small, subtle arrows etched or marked on it. These are your guiding points for where the roof bars will attach. Locate all four of these arrows.
2.2 The Great Cleanse: Wiping Away Grime
Thoroughly clean the areas around these arrow locations with isopropyl alcohol wipes or a solution. Any dirt, dust, or residue can prevent the anti-abrasion tape from sticking properly and potentially lead to scratches. Allow the areas to dry completely for about a minute.
QuickTip: Re-reading helps retention.
2.3 The Anti-Abrasian Armor: Applying Protective Tape
This specialized tape protects your glass roof from friction and potential damage.
Front Side (LH and RH): Measure approximately 227 mm (for Model Y) or 18 mm (for Model 3) back from the front edge of the glass roof to confirm the arrow's location. Align the arrow on the anti-abrasion tape with the arrow on the glass, then carefully apply the tape, ensuring it follows the trim line of the roof. Repeat for both the left-hand (LH) and right-hand (RH) sides.
Rear Side (LH and RH): Measure approximately 412 mm (for Model Y) or 42 mm (for Model 3) forward from the rear edge of the glass roof to locate the arrow on the glass. Again, align the arrow on the anti-abrasion tape with the arrow on the glass, and apply the tape, following the trim line. Repeat for both sides.
Step 3: Securing the Foundation: Rail Clips and Pads
These components are what actually attach to your Tesla's frame under the glass.
3.1 Prying and Clipping: Accessing the Mounting Points
Using the supplied trim tool, carefully lift the rubber seal at each of the arrow locations. While keeping the trim tool in place (to hold the seal open), insert a rail clip so that it aligns with the arrow on the anti-abrasion tape. Ensure the rail clip is properly secured to the J-hook under the roof glass. You might need to wiggle it slightly to confirm it's fully engaged. Once secured, remove the trim tool. Repeat this for all four corners.
3.2 Pad Placement: Identifying the Corners
Each pad is typically marked with an icon to identify which corner of the vehicle it belongs to (e.g., front left, rear right). Place the appropriate pad over its corresponding rail clip, ensuring that the clip and its threads are exposed through the opening in the pad.
Step 4: Mounting the Crossbars: Bringing it All Together
Now for the main event – placing the crossbars!
4.1 Distinguishing Crossbars: Front vs. Rear
It's important to note that the front crossbar is usually longer than the rear crossbar. Make sure you're using the correct one for each position.
4.2 Gentle Placement: Positioning the Crossbars
QuickTip: Reread tricky spots right away.
With the assistance of a friend (highly recommended!), carefully lift and place the front crossbar onto the front pads, ensuring the clip studs are vertical and exposed through the openings in the ends of the crossbar. Do the same for the rear crossbar on the rear pads.
4.3 Hand Tightening: Initial Securement
Once the crossbars are in place, hand tighten the wingnuts onto the clips on all four corners. Do not fully tighten any single wingnut yet. Instead, hand tighten one, then move to the opposite side of the vehicle and hand tighten that one, then the other side, and so on. This ensures an even initial fit.

4.4 Torque Time: The Crucial Tightening Step
This is where the torque wrench comes in. Tighten all wingnuts to the proper specification, typically 2.5-3.5 Nm (2.6 lbs-ft). Alternately tighten both sides evenly to avoid stressing the glass roof. Listen for any unusual noises, but some slight crackling might occur as the components settle into place – this is often normal. Ensure the marking on the wingnuts aligns with the markings on the crossbars (the notch typically faces outboard) for proper engagement and locking. Do NOT over-torque the fasteners, as this can damage the roof glass.
4.5 Lock it Up: Security First
Using the provided keys, lock each crossbar in place. The locking mechanism typically involves rotating the key clockwise on the left-hand side locks and counter-clockwise on the right-hand side locks.
4.6 The Wiggle Test: Confirming Security
Once locked, push and pull on both crossbars vigorously in all directions to ensure they are fully secured and locked in place with no movement. This is your final check for a safe installation.
Step 5: The Finishing Touch: Installing Side Covers
Finally, for a sleek and aerodynamic look, install the side covers.
5.1 Snapping Them On: Guiding Tabs
Starting from the bottom and working your way up, install the roof rack side cover on each side of both crossbars. The bottom of the side covers usually has guiding tabs that insert into the crossbar, ensuring a snug fit. Press the top into place until it clicks securely.
Tip: Stop when you find something useful.
