Simucube Shaft Extension Kit Simucube 3 — jatkotarvike Direct-Drive-wheelbaselle (SC3SEKIT)

The Simucube Shaft Extension Kit Simucube 3 is a set of extension accessories designed for use with Simucube 3 direct-drive wheelbases. It provides shaft extensions and the necessary hardware to change the effective length of the wheel mounting shaft, enabling adaptation to different steering rims, quick releases and custom mounting solutions. The kit is intended to offer a secure mechanical interface while preserving the wheelbase's direct-drive characteristics and rotational accuracy.

Advantages

The kit offers a straightforward mechanical solution to extend or adapt the wheel mounting shaft without permanent modification of the wheelbase. Components are engineered to maintain concentricity and alignment, reducing the risk of increased play or vibration at the wheel. By enabling compatibility with a broader range of steering rims and quick-release systems, the extension kit increases flexibility for custom sim rig configurations and ergonomic adjustments.

Suitable for

• Users who need additional shaft length to clear custom wheel rims or accessories
• Sim racers installing alternative quick-release adapters or non-standard hubs
• Builders adapting a Simucube 3 wheelbase to custom steering columns or mount plates
• Workshops performing fitment tests or temporary setups where shaft removal is impractical

Key specifications

• Compatibility: Designed for use with Simucube 3 direct-drive wheelbases
• Main function: Mechanical shaft extension and adaptation for wheel mounting
• Material characteristics: machined metal components for structural rigidity (material dependent on manufacturer production batch)
• Mounting method: threaded coupling and securing hardware to ensure concentric connection
• Intended outcome: maintains direct-drive feedback characteristics while providing extended shaft reach

How to use

Install the shaft extension kit by following the mechanical sequence: remove the wheel and any existing hub or adapter from the wheelbase shaft, fit the extension onto the shaft ensuring correct orientation and engagement of the coupling surfaces, and secure the assembly with the supplied fasteners to the recommended torque. Refit the steering rim or quick-release adapter onto the extended shaft and verify axial and radial alignment. After installation, check for secure fastening, absence of play and smooth rotation across the steering travel before intensive use.

Recommendations

Use only the supplied hardware or compatible grade fasteners and follow the wheelbase manufacturer’s torque and safety guidelines. Verify clearance for cables, wheel paddles and air flow around the wheelbase; re-check alignment after initial runs and periodically during use to ensure safe, accurate force feedback operation.
