Features:

• 2 Speed Transmission Gearbox:
  • In low gear, it can deliver greater torque, approaching the climbing capability of a brushless motor, making it suitable for tackling complex terrains such as climbing slopes and traversing rough roads.
  • In high gear, it can provide a higher wheel speed than the original, allowing the vehicle to run faster on flat roads. Compared with the single gear ratio of the original transmission, it has stronger applicability.
• 72T large gear paired with a 130 motor can increase torque by 10% compared to the original, enhancing climbing capability. Moreover, it can be connected to the receiver's auxiliary channel via the shifter servo, enabling seamless switching between low-speed, neutral, and high-speed modes, allowing the RC crawler to conquer steeper terrains.
• The power is 100% higher than the original
• CNC machining process utilized, ensuring enhanced product precision, eradicating roughness, attaining seamless fitting, and streamlining installation.
• Plug-and-Play Upgrade,Factory mounting holes ensure zero-error installation,5 minute install, no mods needed.
• note:The shock absorber bracket of the original vehicle's battery seat receiving machine seat needs to be removed
