40mm PMI Dual Pattern Rear Wheel Hub with Single Lock for Versatile Karts

Adaptability defines racing, and this 40mm PMI rear wheel hub embodies it with dual USA and metric patterns. Switch seamlessly between wheel types by removing the index ring—no tools needed for basic conversions. The single lock style, backed by dual pinch bolts, secures everything tightly, ensuring power flows uninterrupted to the rear tires.

• Includes 5/16-24 hardware for immediate installation.
• Removable USA pattern ring allows metric wheel use without drilling.
• Prepped for 5/16-18 set screw to anchor key or tether (screw sold separately).

Made in the USA, this hub's robust build handles the stresses of 40mm axles in pro-level karts. It reduces setup time at events with mixed wheel standards, letting you focus on dialing in suspension or tire pressures. The result? Quicker pit stops and more laps under your belt, building rhythm that translates to faster overall times.

For global series or teams with diverse inventories, its versatility shines—mount American rims for local tracks, metric for imports. The design promotes even bolt tension, minimizing distortion under load and preserving wheel integrity. Racers note enhanced rear grip, especially in wet conditions where secure mounting prevents hydroplaning risks.

Keep your toolbox organized with this all-in-one solution; it's compact yet feature-packed. Whether upgrading a clone kart or spec racer, it elevates performance without complexity. SKU: PM-38-40. Bridge patterns, unlock potential.
