Here's some pics etc of my fitting of the KWs to my own 4.8is:

So onto the coilovers.

This is how the OSF looked to start with with a blown airbag:


The old setup:


And finally removed:


Always nice when you get a present to open:


This is some serious kit. Fully adjustable, Height/Compression/Rebound:


Old with the new:


Front installed:


Now, onto the rear:


The rear airbag once removed:


The rear adjustable spring perch:


All in and replaced:



After a decent clean this is how the X looks (finally air suspension free):




May not look very low but it will settle further and tbh it is a a 4x4 at the end of the day.

It's basically sat where the lower air suspension setting would be, which is fine by me.

Last job now is to get the air suspension coded out.
