The X Factory "Infinity" Kyosho RB5/RB6 Carbon Fiber Idler Shaft is a direct replacement upgrade for the Kyosho RB5/RB6 series models. It's extremely light carbon fiber tube, cut to length so it drops in any RB5/RB6 series vehicle. It's also just ever so slightly bigger than the stock idler shafts, meaning the bearings for the idler gears are an easy press fit. This more perfect fit helps eliminate even the tiniest bit of slop in your transmission, resulting in a car that runs quieter and goes longer between rebuilds.


  • The tighter fit between this shaft and the idler gear bearings provides two main benefits:
  • A quieter transmission, as there's less movement between gears
  • A longer lasting transmission, as less movement means less wear
