Tamiya Mini 4WD PRO Reinforced Gear Cover (for MS Chassis)(15363)

A reinforced replacement for the MS chassis's stock gear cover and battery cover. Where the kit-standard cover simply clips into place, this version is secured with four screws, holding the gearbox together more rigidly and resisting flex at high speed -- flex in this area can let the gears skip mesh under load. Small parts for attachment are included.

• Replaces stock gear cover and battery cover
• Secured with 4 screws
• For MS chassis

The stock MS chassis gear cover relies on friction-fit clips to stay seated over the gearbox, which can work loose under the vibration and impacts of racing and let the cover -- and the gears beneath it -- shift slightly out of alignment. Because this reinforced cover is held down with four screws instead of clips, it keeps even pressure on the gearbox housing throughout a run, which matters because flex there lets gear mesh spacing change under load and can cause teeth to skip or grind. It replaces both the gear cover and battery cover as a pair, so both should be fitted together rather than mixed with the stock clip-on parts.
