Door sills sit directly in the entry path, so shoes, bags and cleaning tools can contact them frequently. SEAL owners shopping for sill protection may see both inner and outer guard sets. They solve related but different problems.
Inner sill guards
Inner guards focus on the cabin-side threshold. This area often sees shoe contact during entry and exit. GlobalBYD currently lists BYD SEAL Inner Door Sill Guards.
Outer sill guards
Outer guards cover a different exposed threshold zone. The store also lists BYD SEAL Outer Door Sill Guards. Compare product photos with your own vehicle because trim geometry can differ by version.
Which should you buy first?
Inspect your car in daylight. If most marks appear on the cabin-side threshold, prioritize the inner set. If the outer entry surface shows more contact, start there. Owners who frequently carry children or passengers may value broader coverage.
Installation priorities
- Clean and fully dry the surface.
- Test-position before exposing adhesive.
- Keep seals, drainage paths and moving trim clear.
- Press evenly and follow product-specific curing guidance.
Door sill guards complement the door edge protection guide and the door anti-kick pad guide. For the wider hierarchy, see the SEAL accessories hub.
FAQ
Are inner and outer sill guards interchangeable?
No. They are shaped for different areas. Use each part only in its intended location.
Do they make the sill scratch-proof?
No accessory can guarantee that. They add a sacrificial contact layer over selected areas.
