SP Low Friction Ball Differential Set (7075 Jura) with 52T Gears: for Tamiya XV01

This is a Jura R ball differential for the XV01 chassis. This replaces the standard plastic R ball differential that comes with the kit. It uses 12 3/32" high-precision steel balls and a Delrin 52T gear in a high-precision 7075 Jura housing. When fitted, this product optimises the difference in rotation between the inner and outer wheels when the car turns, resulting in smoother cornering. Differential effectiveness can be easily adjusted by tightening the ball differential's centre screw.
