In sim racing, small adjustments to your setup can make a big difference in immersion and comfort. The Fanatec DD Shaft Extension is one of those components that may seem minor at first glance but can have a significant impact on your overall driving experience—particularly if you're using a custom cockpit with flexibility in monitor and seat positioning.
What does the shaft extension do?
The DD Shaft Extension increases the distance between your direct drive wheel base and the steering wheel by 150 mm, without requiring any manual cable connection. Its design is as thin as possible, which makes it easier to fit your monitor between the wheel base and the back of your steering wheel. This opens up new possibilities for optimal screen placement, especially if you're aiming for a realistic field of view (FOV) and a cockpit that feels like a true race car.
Please note that the DD Shaft Extension is only compatible with the ClubSport DD and ClubSport DD+ wheel bases.
Who should consider it?
This product is primarily designed for advanced sim racers using custom rigs, typically built from aluminium profile. These rigs allow fine adjustments in seat and monitor position, making them ideal for taking full advantage of the shaft extension. While it can technically be used with Fanatec’s GT Cockpit or CSL Cockpit, this depends heavily on your monitor and seat configuration, and would be considered a special case. For most users, it shines best in setups where ergonomics and realism are highly prioritized.
Key benefits of the shaft extension
One of the main advantages of the shaft extension is the potential for enhanced immersion. By enabling the monitor—or triple monitors—to sit closer to the back of your wheel and lower down, it can visually “blend” the physical steering wheel with the virtual cockpit on screen. This effect can feel like a mixed reality setup, making it easier to forget you’re in a simulator and focus entirely on the track.
Additionally, the DD Shaft Extension is made from high-quality CNC-machined aluminium, with a black-anodised finish for durability and a sleek look. Despite adding distance between components, it maintains a solid, reliable connection with no loss in force feedback detail, ensuring that your performance isn’t compromised.
Whether you're chasing a cleaner, more immersive layout or fine-tuning the ergonomics of your rig, the DD Shaft Extension is a smart, performance-focused upgrade for any serious sim racer.
