All B8 5125 shock absorbers come equipped with industry standard 5/8 inch hour glass bushings and are available in either an eye/eye or stem/eye mount configuration.

What made you choose this particular product?
This valving kit is required to build valving for Bilstein 46mm dampers such as the ASN series.
Is this your first time buying from this brand? Did you consider other brands?
Bilstein shims are designed specifically for their shocks, so they're a guaranteed fit.
Was it easy to install? Any installation tips that will help others?
I used Bilstein's 46mm damper valving manual (). The manual clearly lists the parts used for each valving configuration, but lacks detail on the damper performance curves. It's difficult to predict what you're going to get without a shock dyno to baseline each type of valving.

Performance in mind. A fit and forget part

Yes this is the very first time. After hearing about them I want to try them.
Was it easy to install? Any installation tips that will help others?
2 bolts per schokabsorber, so that is very easy. Ad anti seizing compount on the full length of the bolt as this stops the metal bushes rust solid on the bolts. For the ease of removing later.
