Range Rover Boge Unit to Coil Conversion

Range Rover Boge self levelling unit to coil suspension conversion

  • I used both balls from the Boge unit.
  • The coil is from the front suspension of a Mazda 323 Hatch Back.
  • The coil should be long enough in its normal state to handle the full travel of the suspension and narrow enough to fit between the wishbones.
  • The top ball was screwed straight to the Mazda 323 front suspension top coil holder.
  • The bottom ball required some modification to accommodate a 50 mm extension on the bottom holding plate.  The stud from the ball was removed and the ball was drilled and tap for a 10 mm bolt.  Do not drill right through the ball.
  • The bottom coil holder is a 5 mm thick plate  with a piece of pipe welded to it which is just smaller than the inside diameter of the coil.  The height of the pipe is about 15 mm.
  • The coil is fixed to the bottom holder in the same manner as the suspension coils on the Range Rover.  A piece of flat bar over the lower section of the coil.  This is bolted to the lower plate.
