- Very useful in setting up ride height
There are three elements in setting up a coil over correctly. The first is the amount of preload. This is set by adjusting spring perch height. The second is the free travel or gap between the top of the shock and the bumpstop. This is affected by preload. There are three ways to adjust this. 1) Change the preload. 2) Change the length of the bumpstop. Or 3) Use a shim or 'packer' to reduce the gap. The last element is ride height. When pre-load and bumpstop gap are where you want them to be and ride height is too low you need a shim between the coil over and the chassis. This is that shim.
