Designed for scale realism, these rear hubs provide proportions suited to detailed 1/10 scale RC racing chassis. Their dimensions are intended to match compatible B64 rear suspension and wheel mounting components. The hubs can be paired with matching axles, wheel hexes, bearings, and suspension hardware for a cohesive rear assembly. Their compact design integrates naturally with the chassis while maintaining the intended scale proportions. Compatibility should be checked with the intended B64 chassis, axle, wheel hardware, and related suspension accessories before installation.
