About these parts
The Lexus GX550 arrived for the 2024 model year, replacing the GX460 and moving the platform onto Toyota's TNGA-F body-on-frame architecture with a twin-turbo V6. It shares that architecture with the Land Cruiser 250, the third-generation Tundra and the 2025 4Runner, which is why parts increasingly cross between those platforms.
Because the GX550 is a clean break from the GX460, parts for the earlier truck do not carry over.
