2024+ Tesla Model 3 Highland Rear Bumper Lip Diffuser ABS Body Kit

ABS Rear Bumper Lip Diffuser for Tesla Model 3 Highland 2024+

Give the rear of your Model 3 Highland a more aggressive, lower-profile appearance with a vehicle-specific ABS rear bumper diffuser. Designed around the factory bumper contours for a clean integrated fit without drilling.

Sharper Rear-End Styling

Lower, Wider Visual Profile
The diffuser extends the visual depth of the lower rear bumper for a more performance-oriented appearance.

Integrated Body-Line Design
Its molded profile is designed to follow the Highland bumper rather than looking like a generic universal add-on.

Matte Black Finish
The current supplier selector shows a black low-gloss finish for a contrasting lower-bumper appearance.

ABS Construction

About the Finish

The current supplier selector displays the color as “Mattle Black,” which appears to refer to a matte black finish. This listing uses the clearer term “Matte Black.”

⚠️ ABS — Not Real Carbon Fiber

The supplier marketing text references styling inspired by carbon-fiber appearance, but the published product material is ABS. Do not describe this product as genuine carbon fiber unless a separate real-carbon variant is specifically confirmed.

Additional Lower-Bumper Surface Coverage

The diffuser adds another exterior layer around the lower rear bumper, which may help reduce direct contact from light debris and minor surface scuffs during normal driving.

It is primarily an exterior styling component and should not be treated as a structural bumper reinforcement or impact-protection system.

⚠️ Cosmetic Protection Only

This accessory may help shield covered surfaces from light road debris and minor cosmetic contact, but it is not designed to prevent collision damage, dents or structural bumper damage.

Diffuser-Style Aerodynamic Profile

The rear lower section uses a diffuser-inspired shape intended to visually manage the transition beneath the rear bumper.

The supplier states that the contour is designed to improve airflow around the rear of the vehicle.

⚠️ Aerodynamic Performance Is Supplier-Stated

The supplier claims improved rear airflow, stability and downforce, but does not publish wind-tunnel data, downforce measurements or independent aerodynamic testing for this product. This listing therefore does not guarantee measurable performance gains.

Vehicle Compatibility

⚠️ Does Not Fit Model 3 Highland Performance

This rear diffuser is molded for the standard / non-Performance Model 3 Highland rear bumper. The supplier explicitly states that it does not fit the Model 3 Highland Performance version.

⚠️ Not for Pre-Highland Model 3

The bumper geometry differs between Model 3 Highland and the earlier Model 3. Do not order this product for Model 3 2017–2023.

3M Adhesive + Hardware Installation

1. Clean the Rear Bumper
Wash and dry the lower bumper area thoroughly. Remove wax, oil, dust and detailing residue from all adhesive-contact surfaces.

2. Dry-Fit the Diffuser
Position the diffuser against the bumper before removing any adhesive backing.

3. Confirm Alignment
Check the center position, edges and surrounding panel gaps before permanently securing the part.

4. Apply the 3M Adhesive
Remove the backing from the automotive-grade adhesive and press the diffuser firmly against the compatible mounting surfaces.

5. Install the Mounting Hardware
Secure the diffuser using the supplied hardware at the intended mounting locations.

6. Final Inspection
Make sure all sections are secure before driving and recheck the mounting points after initial use.

No Drilling Required

The supplier states that the diffuser installs using automotive-grade 3M adhesive and mounting hardware without drilling or permanent body modification.

⚠️ Professional Installation Recommended

Because this is a large exterior body component, correct alignment and secure fastening are important. Professional installation is recommended if you are not experienced with exterior body-kit components.

⚠️ Check Ground Clearance After Installation

The supplier states that the diffuser maintains normal ground clearance, but does not publish an exact clearance measurement. Because the accessory extends below the factory bumper area, use care around steep driveways, curbs, wheel stops and uneven surfaces.

Specifications

⚠️ Exact Dimensions & Aero Data Are Not Published

The current supplier page does not publish the diffuser's exact dimensions, weight, measured ground-clearance change, drag coefficient change, downforce value or wind-tunnel test data. Do not add numerical aerodynamic claims unless separately verified.

Package

Includes the rear bumper diffuser body-kit components supplied for this listing together with the corresponding adhesive and mounting hardware. The supplier does not publish a complete item-by-item hardware count.
