3d printed ABS relocation spring for Traxxas TRX-4
It allows to separate the spring from the shock and to create the spring effect on many real elaborate Defenders.
The kit fits without excessive changes, you have to open the wheel arch of the body just enough to fit the new column that is screwed to the original.
Portal drive axle mount rear must be filed to make the lower spring plate fit.
Remaining parts can be assembled without other modifications.
The kit is designed to give a minimum effect already with the original shock absorber, with which you loose a little compression but you gain extension. With longer shock absorbers you can gain both compression and extension. The column has various holes for personal adjustment.
The kit is not designed for extreme uses, so no jumps, no weighted kits.
