Help with Bilstein 5125 sizes

[nbrown2500]

Can any of you guys tell me what item number 5125 shocks you are running on your Blazers with a 6in lift. And what is the difference between the valving options of 170/60 and 255/70. I will be using the stock shock mount locations. Thanks

ORD has a nice chart on this page for Bilsteins. I’ve been told for the valving, 170’s are for dualshocks and the 225’s are single shock setups.

You can also use this page that has a good chart with part numbers.

Thanks for all the information. I think I need the 10.17" travel shocks in the front while using the existing shock mounting point and the 12" travel shocks in the rear.

Only way to truly know is to break down your leaf packs and cycle. Remove all except the main leaf, and put a spacer(a 2x4 piece of wood works well for this) and cycle. If not you are just guessing.
