Quick Answer

Install the Carrera Metalgear Upgrade Kit by replacing your Profi RC's stock plastic gears with the included metal versions (370410200 and 370410201). You must also install a new transmission housing (sold separately).

Why Upgrade to Metal Gears?

Plastic gears in RC cars can wear down or strip under heavy use, especially on rough terrain or during high-speed runs. The Metalgear Upgrade Kit replaces those weak points with durable metal components, extending your vehicle's lifespan and reducing the need for frequent replacements.

Important: You Need a New Transmission Housing

This upgrade requires a new transmission housing (models 370410817, 370410818, or 370410819) because the metal gears have different dimensions than the stock plastic ones. The housing is not included in the kit and must be purchased separately. Check your vehicle's manual to confirm compatibility before starting.

Installation Steps

  1. 1. Disassemble the Rear End: Remove the rear wheels, axle, and stock transmission housing from your Profi RC car. Keep screws organized by location. Common mistake: Forgetting which screws go where. Use a labeled container or take photos before disassembly.
  2. 2. Install the Metal Gears: Place the 370410200 metal gears onto the axle shafts, ensuring they seat fully. Then install the 370410201 metal gear into the new transmission housing. Check that the gears spin freely without binding. If they stick, realign them before tightening.
  3. 3. Assemble the New Transmission Housing: Fit the new transmission housing (370410817, 370410818, or 370410819) over the installed gears. Secure it with the provided screws, tightening evenly in a cross pattern. Over-tightening can crack the housing. Tighten just until snug, then verify gear movement.
  4. 4. Reattach Rear Wheels and Test: Reinstall the rear axle and wheels. Spin the wheels by hand to confirm smooth operation before powering on the car. Listen for grinding noises during the hand-spin test. Any grinding means a gear is misaligned—disassemble and reposition.
