This is an optional Team Losi Racing Front Overdrive Gear Set, and is intended for use with the Losi 8IGHT family of 1/8 buggies. This gear set uses a 42 tooth ring gear, compared to the stock 43 tooth ring gear that is included with the stock 8IGHT 2.0, creating front overdrive. The ring and pinion gears are both laser etched to ensure the gears are not mixed with the stock ring and pinion. The overdrive gear set provides smoother off-power steering and increased on-power steering. On larger high-speed tracks this has dramatically improved the performance of the 8IGHT 2.0. The TLR Overdrive Gear set can be used in all 8IGHT Buggies including the 8IGHT-E and L8IGHT Model.
