I think I understand what you are asking, but you mean to say retainers instead of keepers.

Yes you need to use the retainers and keepers that came with the springs. Dont try to mix and match unless you have verified:

1) that the springs are the same diameter
2) the height of the retainers are the same
3) the angle the keepers are cut at are the same
4) the notch on the keepers are at the same height
