⚠ BEFORE YOU BUY — PLEASE CHECK
• A steering boss is required and is NOT included. Rapfix II mounts between your steering boss (hub) and your aftermarket wheel. You must purchase the correct Works Bell boss for your specific vehicle separately.
• Steering wheel is NOT included. This is the quick-release coupler only. Compatible with any 6-bolt Momo / Sparco / Nardi pattern wheel, or 12-bolt multi-pattern wheel.
• Adds height to the wheel. Rapfix II adds ~63 mm of height between hub and wheel. If clearance is tight, consider pairing with a Works Bell short boss.
• Airbag / SRS warning. Installing a quick release removes the factory airbag. This is a track / show / off-road consideration in many jurisdictions. Check your local laws before fitting to a street vehicle.
• Beware of counterfeits. Fakes are widely circulated. Genuine units carry "Made in Japan" + Works Bell silk printing on the sleeve and a laser-engraved patent number on the plug. This unit is sourced through Japan's authorized retail channel.
• Hot weather caution. Per Works Bell, the aluminum body can become very hot in direct summer sunlight.
Why this one
🇯🇵
The original — not a copy
Works Bell invented the ball-lock quick release. This is the patented original, made in Japan — not one of the cheap lookalikes that flood overseas markets.
⚙️
Cold-forged A5056 aluminum
Same forging method used for high-end aluminum wheels. The flow-line grain structure delivers strength a cast or billet imitation cannot match.
🔒
Zero play, zero rattle
Steel balls maintain constant pressure on the plug. Even after thousands of cycles, the wheel feels solid — none of the wobble cheaper releases develop.
⚡
One-action attachment
Push the wheel on — it locks. No fumbling with a sleeve while holding the wheel. Press the safety button and pull to release.
🪶
174g lighter than the original
The Rapfix II's aluminum sleeve replaces the steel sleeve of the first-generation Rapfix — meaningful unsprung weight off the steering column.
🏁
Race-certified
TRA-approved for the Toyota GAZOO Racing GR86/BRZ Cup. The same hardware that runs in series competition in Japan.
