Precision Engineered Wheel Hub SolutionDesigned for 1/18 scale enthusiasts, these wheel hex hubs combine military-grade durability with precision fitment. The 7075-T6 aluminum construction undergoes a three-stage hardening process, achieving 90HB hardness for superior resistance against rock strikes and crash impacts. Both hub depths (9mm/0.37" and 4mm/0.17") maintain original track width while allowing wheel offset adjustments for customized stability.
Advanced Compatibility FeaturesDirect replacement for the OEM AX31516 assembly, these hubs feature:
12mm/0.47" hex drive compatible with standard 1.5mm wheel nuts
Precision-milled 2.0mm wheel mounting surfaces for vibration-free rotation
Integrated 3° angled contact surfaces to prevent debris accumulation
Performance-Driven DesignThe deep (9mm/0.37") hubs provide extra leverage for technical crawling, while the shallow (4mm/0.17") variants reduce unsprung weight for speed-oriented setups. All hubs include:
Cross-knurled inner surfaces increasing wheel grip torque to 8Nm
Chamfered edges protecting wheel bearings from dirt ingress
Laser-etched depth indicators for quick identification
