Material Specifications

  • Main gear: 30T, powder metallurgy (MIM metal injection molding) for high density and strength
  • Differential housing: 7075-T6 aerospace grade aluminum alloy
  • Outdrive cups: Hardened chromium steel
  • Internal gears: Powder metallurgy steel
  • Fasteners: High-strength alloy steel screws
  • Differential oil: Pre-filled with 3000cSt silicone oil (or dry ¨C check your version)

Core Advantages

  • MIM gear technology: Provides near-forged density and wear resistance, far superior to stock sintered or plastic gears
  • Aluminum housing: Eliminates flex and gear misalignment common with stock plastic diffs
  • Precision fitment: Direct upgrade for ARRMA GROM 1/18 scale models
  • Ready to install: Pre-assembled with bearings and screws, saves time
  • Smoother power delivery: Chromium steel outdrives reduce wear on driveshafts

Usage Notes

  • No break-in required for MIM gears, but recommended to run gently for first battery pack
  • Recommended oil: 3000cSt silicone oil; re-lubricate every 10-15 runs
  • Check screw tightness after initial runs as housing may settle
  • Ensure correct orientation when installing (front vs rear marked on housing)
