Self levelers.

Simple question.
Maybe not such a simple answer.

How do the self leveling shocks work that are fitted to the Rover 75? IF that is the correct name for them.

I know the article is Volvo related, but it also applies to our cars (where self levelling rear suspension is fitted).

Hello Paul. Are you sure every 75 is fitted with self levelling rear suspension?
I'm not sure my Cowley built V6 has it.
Moreover I've swapped the 4 shock absorbers when I bought her (they were fully worned) for new TRW ones I know nothing about.
Thank you for clarifying my poor knowledge.

Hello Arnaud,
The self levelling rear suspension was only fitted to some tourers, it was an optional upgrade I believe.

Thanks Paul.

I'm relieved because I've got all the genuine Rover workshop manuals (in French, from a then Rover dealer) and I hadn't seen anything of the sort anywhere.

It was an optional extra/upgrade on Tourers I chose it for mine.

Yep! same here when Windrush bought his Tourer he also had them fitted because he towed a van.

As I understand things, they were only an option on 75 Tourers, and not on ZT-Ts.

It is likely that the self-levelling shock units were made by Nivomat. They made similar items for other cars, and BMW touring motorcycles.

In terms of their operation, I think a particular shock length is set, (possibly via the relative alignment of two holes). If extra load then causes the spring to compress, and thus the rear to lower, fluid is pumped into the shock absorber's preload reservoir by the natural movement of the suspension until the holes align again.

also, I think that they were only fitted at the rear of the car. (I'm happy to be corrected on this point.)

Boge Nivomat being the full name. NLA some years ago.
