Their front control arm bushings require you to thoroughly clean and re-use the outer sleeves.

The inner leaf spring bushings are in the kit but they don't show outer bushings in the product pictures. The instructions say the outer bushings need to be removed and don't mention re-using them. Since they specifically mention re-using the sleeve in the control arm instructions I would say they don't intend you do the same on the leaf springs.

f this doesn't clarify the situation for you I would email their tech support to ask.
