Moving the shock node is great if your going for proper scale suspension, if not your just removing suspension travel. In the shock prop line you this is what it looks like (you will have to move the shock body, coil and shock shaft)

First three numbers are the reference nodes the meshes use for movement perimeters. The first decimal number is to move a mesh up and down, second number is to move left and right and the last decimal number is to move front to back. You will have to tinker with the numbers a bit though, use increments of 0.1 or 0.05. The meshes move drastically to small number changes.
