Kyostar KD8381 Universal Aluminum D-Shape Steering Wheel Quick Release Hub | Racing Drift | Auto Par

What is a Quick Release Hub?

A quick release hub is an adapter that sits between your car's steering column (via a boss kit) and the aftermarket steering wheel. It allows for the rapid attachment and detachment of the steering wheel, serving as both a convenience feature and an anti-theft device.

Installation Steps (General Overview)

Warning: Disconnecting the airbag system will disable driver and passenger safety features. Installation on road-legal vehicles with airbags is intended for off-road or show use only.

1. Safety First: Disconnect the vehicle's battery to prevent accidental airbag deployment.
2. Remove OEM Wheel: Follow your vehicle's service manual to safely remove the factory steering wheel and airbag assembly.
3. Install Boss Kit: Mount a vehicle-specific boss kit onto the steering column splines. This is essential as the Kyostar hub is universal.
4. Attach Quick Release: Bolt the Kyostar D-Shape hub (male end) to the boss kit.
5. Mount Steering Wheel: Attach your aftermarket steering wheel to the corresponding flange (female end) of the hub.
6. Connect & Test: Reconnect any horn wiring and ensure all bolts are torqued securely before reconnecting the battery and testing functionality.

Price Range

Based on similar Kyostar models, the KD8381 typically falls in the budget to mid-range category, with prices ranging from approximately $20 to $60 USD, depending on the retailer and finish.

Where to Buy

Kyostar products are widely available on global e-commerce platforms such as AliExpress, eBay, and through various auto parts distributors.

Compatibility Check

This hub is universal, meaning it uses a standard 6-bolt pattern (typically 70mm PCD) to fit most aftermarket steering wheels from brands like Momo, Sparco, and OMP. However, you must purchase a separate boss kit that is specifically designed for your car's make, model, and year to connect it to the steering column.

User Feedback Summary

Kyostar is known for offering affordable entry-level performance parts. User reviews often highlight:

• Pros: Excellent value for money, lightweight aluminum construction, easy to install, provides a solid "click" when locked.
• Cons: Metal spokes may feel less robust compared to premium brands (e.g., Sparco, OMP), and the finish may not be as refined. Some users report that supplied screws may have uncommon thread pitches.

Overall, it is considered a good option for budget builds, sim racing rigs, or drift cars where cost is a primary concern.

Warranty & Support

Warranty periods may vary by seller. It is recommended to check with the specific retailer at the time of purchase. For technical support, contact the manufacturer or seller directly.

Cleaning & Maintenance

To maintain the hub's appearance and function:

• Use a mild soap and water solution to clean the aluminum body.
• Avoid harsh chemicals or abrasive cleaners that could damage the anodized finish.
• Periodically check the locking mechanism for debris and ensure all mounting bolts are tight.
