  • Ultra-Compact and Featherlight Build: Weighing only 30g with dimensions 52.5×33.5×18.2mm, this transmission reduces rotational mass while dramatically lowering your crawler's center of gravity for superior rock-climbing stability
  • Strong Durability: Features laser-cut carbon fiber housing, hardened chromoly steel gears, and Grade 5 titanium output shafts - engineered to withstand extreme comp rig conditions while maintaining silky-smooth operation
  • Precision Low-CG Engineering: 3:1 gear ratio with 36T 48P spur gear optimizes torque distribution. Compatible with 11T-18T pinions (not included), delivering unmatched crawling performance without sacrificing speed modulation
  • Pro-Level Installation Flexibility: Includes CNC aluminum sliding shim and M3 hardware for seamless integration with Axial 3-gear systems. Precisely spaced 25mm motor/27.5mm skid mounting patterns ensure universal 1/10 chassis compatibility
  • Competition-Ready Silent Operation: Advanced meshing geometry and premium materials significantly reduces gear noise (which can be further minimized with grease application), allowing you to concentrate fully on technical control during crucial competitive moments
