Noram GE Ultimate Clutch Drive Hub - 3/4" Bore - 4-Cycle Racing

When you are pushing your kart to the absolute limit, relying on inferior racing go kart parts will cost you podiums. Power transmission starts at the crankshaft, and the Noram GE Ultimate Clutch Drive Hub (NAU061) is the cornerstone for bulletproof drivetrain reliability. Engineered specifically for 3/4" shafts, this heavy-duty steel hub locks in torque without fail, ensuring every ounce of engine power translates directly to the track. In competitive racing, you need an unflinching grip that allows for full-throttle application without a split-second of hesitation.

Precision Engineering for Comet Parts & Drivetrain Synergy

To maintain a competitive edge, your entire setup—from the engine down to the accessories wheel—must work in perfect harmony. The Noram GE Ultimate hub prevents catastrophic slippage during aggressive shifts and high-RPM engagements. Whether you are running standard sprockets or integrating specialized comet parts, this hub guarantees zero play. Its superior keyway design handles the extreme stress of high-horsepower 4-cycle engines, reducing maintenance and keeping you out of the pits. When you demand speed gains, this indispensable component delivers by maintaining absolute structural integrity under load.

Unflinching Grip Down to the Last Tire Bolt

Durability is non-negotiable in junior and senior classes alike. A single loose tire bolt or a slipping clutch hub can end your weekend early. By upgrading to the NAU061, you secure a direct, unflinching link from your engine to the asphalt. This hub is adaptable to various chassis configurations and supports small pattern sprockets, making it an indispensable asset for serious speed gains. Built to endure the brutal heat and vibration of competitive racing, it delivers full-throttle confidence without hesitation.
