When you're building a championship-caliber racing kart, managing extreme torque transfer from a four-disk clutch demands a zero-deflection foundation. The Buller Built Bully Turbo Jackshaft Drive Hub (MPN: 098-347) is engineered specifically to mate 4-disk clutches to 3/4" jackshafts with unerring accuracy. Turbo setups and high-output modified engines thrive on solid drivelines; this vented drive hub minimizes vibrational harmonics and prevents flex under massive boost spikes. By channeling power directly to the wheels without parasitic loss, it guarantees blistering straight-line speed and aggressive corner exits.
Outperforming Standard Exhaust Parts and Drivelines
Jackshaft efficiency is the critical link in layouts where engine placement demands extended drive-lines. This hub's precision-machined 3/4" bore ensures direct shaft integration, maintaining perfect alignment through the gears. Teams appreciate its role in modular builds, allowing rapid swaps between clutch types while keeping components sorted in custom racks alongside your trailer and accessories. Whether you are dialing in your exhaust parts for maximum backpressure or tuning your chassis, eliminating driveline flex is non-negotiable. When you are searching for a new go kart frame for sale to build your next unlimited-class monster, pairing it with a Buller Built driveline ensures your chassis handles the power.
Translating Jackshaft Power to Your Top Tire
In high-RPM karting, instant grip is everything. Data from dyno tests show improved power curves, translating to on-track advantages like better top-end pull and quicker launches. It pairs seamlessly with Bully accessories for a holistic upgrade, ensuring that every ounce of power reaches your top tire for maximum traction and reduced lap times.

Frequently Asked Questions
Q: Is this hub compatible with standard 2-disk clutches?
A: No, the Buller Built Bully Turbo Jackshaft Drive Hub is specifically engineered for 4-disk clutch configurations to handle the increased torque loads of modified engines.
Q: Does this hub require any special tools for installation?
A: While standard shop tools are generally sufficient, ensure your 3/4" jackshaft is clean and free of burrs to allow the precision-machined bore to slide on without force, maintaining the integrity of the fit.
Q: Why is the vented design important for my racing setup?
A: The vented design is critical for high-RPM racing because it allows for rapid heat dissipation during aggressive clutch engagement, preventing heat soak that can lead to clutch fade or premature component wear.
Q: Can I use this hub on a standard LO206 engine?
A: This hub is designed for high-output modified engines and turbo setups. For standard LO206 or Clone racing, ensure your clutch configuration matches the 4-disk requirement of this hub.
Q: How does this hub help with driveline vibration?
A: The hub is CNC-machined for perfect balance and rigidity. By eliminating flex between the jackshaft and the clutch, it minimizes vibrational harmonics that can otherwise travel through the drivetrain and affect engine performance.
