Got tired of breaking stock parts on my Clod buster so designed these. The tubes are printed in 4 parts and are assembled with self tapping screws.

Compatible with the stock Steering Knuckles but you can use the ones I designed for a much tougher setup. See my other items.

Required hardware per axle and procedure
Always ream out any holes with the appropriate drill bit. 

8pcs  of 2x16mm Self tapping socket cap screws
Use a 1.5mm drill bit to ream out the holes that attach the case mount to the tube.

8pcs of 3x10mm Self tapping flathead screws
use a 2,5mm drill bit to ream out the holes for the Kingpin mounts
Also use a 5mm drill bit to ream out the Kingpin holes

8pcs  of M3 Nylon lock nuts
Insert these into the provided  sockets in the Case mount part.

8pcs of M3x12mm Socket cap screws(Can use stock JIS Screws)
Use these to mount the tube assembly to the case.

They are setup so you can install a servo on either side of the axle.
When using the servo on axle you cannot use the upper link mounts on the C Hub. alternatively, you can use my Bumper servo mount if you want to use the C Hubs for a 4 link setup.
