The ArmorKun BZT-H-03 is a custom aftermarket AMG steering wheel built around a broadly adaptable mounting platform. Depending on the vehicle year, original airbag, control layout, and electronic configuration, it can be configured for major Mercedes model families including A-Class, B-Class, C-Class — including C300, C43 AMG and C63 AMG — E-Class, S-Class, CLA, CLS, GLA, GLB, GLC, GLE, GLS, G-Class, SL, SLC and AMG GT applications. Mercedes-Benz parts information confirms that even within the Mercedes Benz C-Class, steering wheel and paddle configurations can vary by year and equipment, so exact fitment should be verified before production. Some 2005–2009 vehicles may also require mounting-base modification during installation.

The BZT-H-03 is positioned differently from a conventional leather-based Mercedes steering wheel. Its visual focus is exposed carbon fiber, while the LED system adds information directly within the driver’s field of view. Together with the carbon paddle shifters, this gives distributors a product aimed at customers seeking a more technical, performance-oriented cabin upgrade.
That makes the model particularly relevant when developing custom Mercedes steering wheels for AMG-style applications, a Mercedes Benz C300 steering wheel replacement, or upgrades for popular C-Class, CLA, GLA, GLC, GLE, GLS and SL vehicles.
The carbon sections also provide a better separation from the normal factory leather wheels. To achieve a different tactile specification the grip material can be discussed, such as Alcantara or other leather options, as part of a custom program. So, if a buyer desires that the steering wheel be produced using a custom carbon fiber material, as well as exclusive trim and functionality, they can properly design the material, trim and functionality with the manufacturer or supplier before the wheel is manufactured.
Broad base compatibility does not mean every Benz uses the same electronic architecture. A car steering wheel may differ in airbag shape, multifunction controls, paddle-shift hardware, wiring, heating, driver-assistance controls, and trim even between vehicles from the same Mercedes-Benz series.
For accurate OEM compatible fitment, distributors and repair shops should provide the exact model, production year, and clear photos of the original wheel. This is particularly important for the LED display and carbon paddles: the display requires an available OBD connection, while the paddle-shift function requires the car to have the corresponding factory feature.
Base modification might be required in older Mercedes vehicles, particularly on some models from 2005-09. Getting these details confirmed prior to production makes installation easier to predict, and ensures that a widely available aftermarket steering wheel can not be used as a plug and play part.
The outcome is an aftermarket wheel that goes beyond just looks and feelings, featuring a carbon wheel with integrated driver information and paddle control which alters the way the cabin appears and the way that the driver interacts with the vehicle when driving.
