The Tamiya 51108 Gear Cover is a practical component for anyone maintaining a TB Evolution IV chassis. Its main role is to stop dirt and stones getting into the gears, helping maintain smooth running on mixed surfaces.
Specifically made for the TB Evolution IV, this cover offers a snug, factory-fit style protection that does not add needless bulk. It reduces the chance of foreign matter entering the gearset and causing premature wear.
Installing the Tamiya 51108 is straightforward and uses basic hand tools. Make sure screws are tightened evenly, confirm there is no rubbing on the gears, and do a short test run to check alignment.
