The lift kit from the original file was a bit too much for me, I didn't like the look.Edited the file for less lift.
I then wanted more flex on the rear axle and came up with the revolver type shackle. It gives alot more flex. You will need 2 m3x8 bolts and lock nuts. Do not tighten completely as the parts need to move.
