Before ordering a power trunk support, answer two separate questions: does this part match your car, and has the existing support actually been identified as the repair needed? This CarLightBulb listing covers a generic rear-left replacement for the 2021–2023 Tesla Model 3. Start with the original part, not just the vehicle name.
Product snapshot
Start With the Left-Side Part, Not a Broad Model Search
The listing identifies this support for the rear left, also described as the rear driver side. Use rear-left placement as the primary reference rather than assuming that “driver side” means the same thing in every market. This is not a listing for a right-side support or a matched pair.
The supplied manufacturer part numbers are 1551488-99-B and 155148899B. Compare the original label with these identifiers before purchasing. If your existing label shows another number or revision, ask for compatibility confirmation instead of assuming that a similar-looking assembly will interchange.
What This Listing Actually Supplies
Product snapshot: listed application, 2021–2023 Tesla Model 3; placement, rear left; condition, brand new; color, black; SKU, C219-A055-A~1. The package description specifies one rear tailgate lift support. The listing calls it a direct replacement, but that description does not replace vehicle-specific verification.
The photos show a black cylindrical body, a ribbed protective section, end attachments and a wired connector. Treat those visible details as comparison points. Do not assume that separate mounting hardware, additional wiring or other installation accessories are included; the package description does not specify them.
Separate the Complaint From the Purchase Decision
Write down what prompted the repair: incomplete travel, inconsistent movement, unusual noise or visible damage. Record when it happens and whether anything appears to obstruct movement. Give that information to the person diagnosing the car rather than using one symptom as proof that the left support needs replacement.
If the cause remains uncertain, arrange diagnosis before ordering. Buying this assembly makes the most sense when the repair has been narrowed to the rear-left support and its identity matches. It should not be presented as a guaranteed cure for every powered-trunk complaint.
Compare the Connector and Mounting Details Before Removal
Photograph the original label, connector, wire routing and both attachment ends while the existing assembly is still installed. Compare connector shape, visible locking features and mounting configuration with the product photos. Ask for clearer product images if an important detail cannot be checked.
Have the VIN available when requesting confirmation, together with the model year and original part number. A year-range match alone leaves unanswered questions. If the label is missing or a previous repair changed the assembly, explain that uncertainty rather than treating photographs as conclusive fitment evidence.
Plan the Installation Before Committing
Use a vehicle-appropriate repair procedure and establish how the trunk lid will be safely supported before any support is detached. Ask the installer to confirm electrical precautions, attachment requirements and any necessary post-installation checks. This buying guide is not a removal procedure.
The seller supplies an installation video for reference only and warns that it may not be completely accurate. No installation time, tool list or programming requirement is established here. The listing states a 180-day warranty and a 60-day return application window after receipt; confirm applicable conditions before purchase.
Before-order checklist
- Confirm the listed 2021–2023 Model 3 application.

- Verify rear-left placement.
- Compare connector and mounting photos.
- Confirm the diagnosis before buying.
- Plan safe installation and check return conditions.
Questions buyers often ask
Does this include both trunk supports?
No. The supplied package description lists one rear-left tailgate lift support, not a pair.
Is this a genuine Tesla part?
The title identifies it as generic. The supplied information does not establish genuine Tesla manufacture.
Is model year enough to confirm fitment?
No. Compare the original part number, connector, side and photos, and request VIN-based confirmation where compatibility remains uncertain.
Confirm the Match Before Ordering
Review your original label and connector photos against this listing. If any detail differs, send your VIN and comparison images to CarLightBulb before purchasing.
