When sourcing new parts from a premier go kart shop, every ounce of rotational mass matters. The PKT 40mm x 35mm Shorty Rear Wheel Hub is engineered to free up your chassis, specifically designed to let the axle do its work without binding. By reducing the footprint on the axle to a mere 35mm, this hub minimizes lateral stiffness, allowing your kart to flex naturally and carry maximum momentum through the apex. It's the ultimate upgrade for racers looking to maximize their briggs and stratton lo206 horsepower output by eliminating drivetrain drag and optimizing rear grip.
Precision Engineering Beyond Standard New Parts
Unlike standard cast hubs, the PKT Shorty is CNC-machined from aerospace-grade aluminum, delivering a rigid yet lightweight interface between your axle and wheels. The single 8mm pinch bolt provides superior clamping force without distorting the axle tube. To guarantee zero lateral movement under heavy cornering loads, PKT integrated dual 6mm set screws that lock the 8mm key firmly in place. This ensures your rear track width remains perfectly consistent, lap after grueling lap.
Complement Your Setup: From Brake Pistons to Engine Bearings
A balanced chassis requires harmony across all components. Just as you wouldn't compromise on high-performance brake pistons for stopping power or low-friction engine bearings for top-end speed, your wheel hubs demand the same level of scrutiny. The 52mm metric bolt pattern comes standard with 8mm zinc-plated series 4100 wheel studs, providing bulletproof reliability during rapid tire changes. Finished in a sleek black anodize with laser engraving, it looks as fast as it performs.
Maximize Tuning Potential with a Fresh Carb Kit and Hub Geometry
Tuning for changing track conditions is where races are won. While adjusting your fuel mixture with a precision carb kit handles the engine's power delivery, dialing in your rear track width with these 35mm hubs dictates how that power translates to the asphalt. The shorter hub length gives you a wider range of adjustment on a 40mm axle, allowing you to widen or narrow the rear track to induce or reduce mechanical grip as needed.

- Superior Clamping System: Features a robust 8mm pinch bolt to secure the hub without lateral slipping.
- Dual Set Screw Design: Twin 6mm set screws lock the 8mm keyway firmly, preventing keyway wallow under load.
- Metric 52mm Bolt Pattern: Industry-standard spacing equipped with high-strength 8mm zinc-plated 4100 series studs.
- Aerospace-Grade Aluminum: CNC-machined construction shaves rotational weight while maintaining structural integrity.
- Black Anodized Finish: Protects against corrosion and track debris, complete with premium laser-engraved PKT branding.
Frequently Asked Questions
Q: Why should I choose a 35mm "Shorty" hub over a standard length hub?
A: The 35mm length reduces the footprint on your axle, which decreases lateral stiffness. This allows your chassis to flex more naturally, helping the kart "lift" the inside rear wheel more effectively and carry better momentum through corners, especially in LO206 classes.
Q: Will this hub fit my current kart setup?
A: This hub is precision-bored for all standard 40mm metric kart axles. It features a 52mm bolt pattern, which is the industry standard for most racing wheels.
Q: How do the dual set screws improve performance?
A: The dual 6mm set screws are designed to lock the 8mm keyway firmly in place. This prevents "keyway wallow," ensuring your rear track width remains consistent and preventing the hub from shifting under heavy cornering loads.
Q: Do I need special tools to install these hubs?
A: Installation is straightforward using standard metric hex keys for the pinch bolt and set screws. Ensure your axle is clean and free of debris before sliding the hub on to ensure a perfect fit.
Q: Can I use these hubs with different axle wall thicknesses?
A: Yes, these hubs are compatible with various 40mm axle wall thicknesses. However, because the hub affects chassis flex, you may need to adjust your axle choice (e.g., moving to a different stiffness) to complement the change in hub length.
