I have a 2015 Pro4x that came with Bilstein 4600 shocks. My understanding is that someone must have put these on aftermarket.

I’d like to find out if I still have the stock Pro4x springs and if so replace them with the softer factory non-Pro4x (or otherwise) springs to improve on road ride quality.

Are the springs stamped anywhere I can see without disassembly?

Can they be checked with a micrometer to tell a difference between the usual springs and Pro4x?

What springs are recommended for ride quality with these shocks for a truck that never sees dirt or more than a 700lb motorcycle in the bed?

Thanks!

there might be part numbers on the coils and leaves somewhere that lets you know what you have. other wise, i don't know if non-pro4 ride any softer as i believe its the shocks that make the rides feel the way they do on these trucks. unless you have a lift



you can look up what part numbers should be on your suspension on that site and then go compare to what you actually have
