Bully Turbo Jackshaft 4-Disk Clutch - 3/4" Bore - Open/Modified Class

Power transfer dictates lap times, and sourcing the right drive-line components from a premier go kart shop is the first step to eliminating parasitic loss. The Noram Ultimate Clutch (Light Shoes / Green Springs) is engineered for high-output kart racing, delivering immediate, slip-free engagement from your go kart engine straight to the rear axle.

Designed specifically for a 3/4" jackshaft, this four-disk powerhouse maximizes low-end torque and optimizes performance out of tight hairpins.

Optimizing Your Clutch Assembly for Carb Engines

When tuning high-revving carb engines, maintaining precise RPM engagement is critical. The Noram Ultimate Clutch’s ring gear style hub provides exceptional durability and rotational balance, ensuring your clutch assembly withstands the extreme thermal loads of competitive sprint and endurance racing. This 4-disk setup allows racers to fine-tune their lock-up RPM, giving you the exact bite needed to launch ahead of the pack without bogging down the motor.

Precision Drive-Line Dynamics

Every component in your driveline must work in harmony. The ventilated friction disks dissipate heat rapidly, preventing clutch fade during long, grueling mains. Whether you are running a modified animal or an open-class 4-cycle, the rotational mass savings provided by the billet construction translates directly to faster spool-up times.

Proper maintenance of your kart parts is essential, and the Noram Ultimate Clutch makes it easy with accessible spring and weight adjustments. By dialing in the exact engagement point, you prevent bogging and keep the engine squarely in its powerband.
