The Tamiya 53667 Speed Tuner Gear Set is intended for the TGS chassis and swaps the factory 10.4:1 gearing for an 8.67:1 ratio, producing faster acceleration and increased top speed for both practice and race days.
These gears use a hard-wearing nylon formula to resist wear under high-speed use. The black coating improves durability and delivers a tidy finish inside the gearbox.
