lol sorry that got cut off.
Yes, with this you will need to disassemble your factory shock system and reuse the coilspring on the bilstein. Unlike with a strut suspension, you cannot assemble these without a spring compressor - at least not that I know of! We do offer offroad adjustable coilover shocks as well as the Rancho quicklift which is a complete coilover system and installs right outta the box
If installing these yourself and dont want to use a spring compressor, take it to a Brake / Suspension shop and they should be able to swap the springs for you for about $50
