Huh, ok. Just curious. Good to know - that experience might save someone some serious coin. I've always been told Nivomats must be replaced with Nivomats. I didn't believe it either and wasted time and money finding out the hard way. I guess the Durango must be different.
Not really sure how those shocks are self-levelling since there are no sensors attached to them. Haven’t investigated the system at all. Shocks looked just like your normal shocks as seen in the pic I posted.
If they were Magnaride, that would be whole nother ballgame.
The only self-levelling stuff I’ve ever worked on have been either hydraylically (old MBs) or air (Ford) operated.
