G550 4x4 Squared - replacing shocks

I may have to do this soon ….. can anyone let me know their experience in terms of replacing with OEM or any after market recommendations?

Thanks!

I have been looking into this - since there are a ton of suspension rebuild shops in SoCal, I reached out to a few, but none of them want to rebuild the KW shocks and told me to send the shocks directly to KW. I have reached out to KW and was told someone would call me back but never got a call

Main reason no one wants to rebuild them is unlike King, Fox, etc - KW doesn't like selling rebuild kits to these shops

I got a quote from the stealership and was told $30K for parts and labor

In collaboration with LeTech and Daimler AG, we developed four electrically adjustable and four non-adjustable dampers for the Mercedes-Benz G500 4x4². On each axle, the Mercedes runs on a total of four coilover dampers with KW technology, making it ideal for any terrain.

Does this mean 4 of them are normal KW V1, and the other 4 are KW DDC?

I found this thread on Bimmerpost - someone bought a set of used BMW spec KW/M Performance coilovers and wasn't able to get a re-build kit from KW or help from the dealership:

Another member used Zoran at TWF Racing to rebuild KW/M Performance coilovers:

But it seems like TWF Racing rebuild motorcycle suspension:

FCPEuro has these listed as compatible for the 4x4:

I am going to reach out to Bill Rader and Letech to see what options are available to us 4x4 owners because it's pretty ****ty not to be able to get coilovers rebuilt and forcing owners to buy new suspension

What's confusing is on that link - it states these two versions: 2x KW V1 and 2x KW DDC

Does this mean 4 of them are normal KW V1, and the other 4 are KW DDC?

I was going to tag Bill Rader on this, but can't recall his username on this forum. He will have a solution for you, and it will likely be much better than $30K in new parts and labor from a stealership.
