Front HS bulkheads allow for diff height adjustment using eccentric bushings. In the front gearbox, the diff height has a 2mm adjustment range in which 2 Dot is for middle diff position. The diff height adjustment is a vital set-up capability that allows quick set-up adaption for either Carpet or Dirt tracks.
Carpet edition runs with lower ride height and to keep the drive shafts straight the differential is placed in upper position.
Dirt edition runs with upper ride height and to keep the drive shafts straight the differential is placed in lower position.
