Hilliard Inferno 11-Tooth Needle Bearing Clutch Driver for Racing

Precision meets performance in the Hilliard Inferno Needle Bearing Style Clutch Driver, a must-have for racers optimizing their 11-tooth sprocket setup. Tailored for needle bearing clutches, it utilizes the race for a snug fit, promoting reduced friction and reliable engagement every time you hit the throttle.

Without the bearing or race included, this driver allows customization—order the HDC-FIRA assembly separately if needed. Its robust construction handles the rigors of competitive karting, from tight corners to straightaway bursts, helping you maintain consistent lap times. The 11T configuration is ideal for balanced gearing, giving that extra punch for acceleration without over-revving.

As an OEM part (8444-47-117), it integrates seamlessly with Inferno systems, keeping your drive-line organized and efficient. No more power-robbing inefficiencies—equip your kart with this driver to gain an edge in every race. SKU: HDC-11B.

Frequently Asked Questions

Q: Does this clutch driver include the needle bearing and race?

A: No, this product is the driver only. You will need to ensure you have the appropriate bearing and race assembly (such as the HDC-FIRA) for proper installation and function.

Q: What chain size is this 11-tooth driver compatible with?

A: This 11-tooth driver is specifically designed for use with #40/41 chain configurations.

Q: Why is it important to use the race with this driver?

A: The race provides the necessary hardened surface for the needle bearings to ride on. Without it, the bearings will not function correctly, leading to increased friction, potential heat buildup, and premature failure of your clutch system.

Q: How does an 11-tooth driver affect my kart's performance?

A: The 11T configuration offers a balanced gear ratio, providing a strong punch for acceleration out of corners while maintaining top-end speed without causing the engine to over-rev on straightaways.
