Thanks. Yes I am familiar with the AGM and their price.Not sure what you mean by "quiet things down," but AGM makes a slider for coil overs. They are well-made, not cheap and arguably not necessary. 3-piece construction with a replaceable liner sleeve. I used them with my original coil over setup and they worked fine.

I'll be fine. Hearings not greatest anyway. Really just curious about these spring bearings.If there's a benefit to standard coil and springs and clevite bushings, it's that they're SUPER QUITE.
