Maximizing rear-end grip and trackside adaptability is non-negotiable when sourcing the best go karts and parts for your racing program. The Performance Mfg (PMI) 40mm Dual Pattern Rear Wheel Hub eliminates the need to carry duplicate spares by seamlessly bridging USA and metric wheel bolt patterns. By simply removing the precision-machined index ring, you can instantly swap between domestic and imported rims without drilling, specialized tools, or compromising concentricity.

Precision Hubs for Wheels: USA & Metric Compatibility
