The launch of the Tesla Model 3 Highland (2024– ) has brought major updates—not only in design but also in the exterior body structure.
For B2B buyers sourcing aftermarket hoods, fenders, doors, and tailgates from China, understanding these differences is essential for preventing model mismatch, reducing returns, and ensuring accurate procurement.
This guide compares the Model 3 Legacy (2017–2023) and Model 3 Highland (2024+) from the perspective of body parts compatibility.

7. What This Means for B2B Buyers
1. Inventory must be separated clearly
Never mix Legacy and Highland parts—they look similar but do not fit each other.
2. Supplier must provide correct model coding
Ask the factory to label all products with:
- Model
- Year
- OEM reference number
- Version type (Legacy / Highland)
3. Packaging must reflect model separation
Especially for fenders, doors, hood, tailgate.
4. Avoid suppliers without tooling experience
Because Highland parts require:
- new stamping molds
- new welding fixtures
- different curvature requirements
Factories without tooling capacity often resell low-accuracy parts.
