RCAWD Front Rear Axle 28T Heavy Duty Bevel Helical Overdrive Gears With 11T Input Gear For HPI 1/18 Venture18

Features:

• Hardness & Wear Resistance
  Forged from high-purity 40Cr steel (1.0-1.5% chromium content) with HRC 58-62 surface hardness—70% harder than carbon steel gears, 120% more wear-resistant. Withstands tooth peeling and chipping during rock crawling/high-speed runs, lasting 3x longer than OEM gears.
• 28/11T Ratio: Torque & Speed Balance
  ~2.54:1 reduction ratio tailored for off-road—2.5x torque boost for 40° climbs, 22% higher power efficiency than 24/12T (10% less loss), balancing climbing strength and flat-road runtime.
• Helical Tooth Design: Smoother Transmission
  60% higher tooth contact ratio than spur gears—"gradual engagement" instead of "sudden impact" cuts noise by 50dB and vibration by 45%. Reduces stress on bearings and driveshafts for longer component life.
• CNC Machined
  CNC machined with ±0.02mm tooth profile error and ≤0.05mm pitch error. 98% power transmission efficiency (15% higher than standard gears) eliminates "power lag" from excessive tooth clearance.
• OEM Fit: Direct Drop-In Installation
  Precision-machined to match Venture18’s axle housing dimensions (bore tolerance ±0.01mm). Installs in 10 minutes with no grinding or drilling—compatible with stock driveshafts and diffs.
