You’ve got a couple options for replacement. Obviously new Nivos are an option, but not wallet friendly. Magical if you haul stuff frequently though.

If you want to retain stock ride height, get a set of non-Nivomat springs (they’re different) and use either S70 AWD non-Nivomat shocks or press QA1 BAR505K t-bars into any P80 FWD shock of your choice.

If you want to lower it, get the aforementioned S70 shocks or make your own AWD shocks and pair them with BNE’s adjustable rear spring perch setup and some Eibach linear springs, then use the front half of a FWD lowering spring kit up front.
As This is a low budget fix i was planning on reusing the tbar from the nivomat shocks. It measures around 18mm so probably to big to just slide into the other shocks from that year which appear to be 14mm, i might have to remove the sleeves from the new shocks bushings

I wasn't planning on any spring changes i'll have to see what things look like when I get the shocks some fudging may be required
the monroe shocks i was looking at had very similar extended and compressed lengths to what these nivomats have. Within a 1/4 inch or so I think

You must change the springs if moving away from the Nivomats. They’re way softer than the conventional shock’s native springs and have an effectively lowered ride height if used with regular shocks.

Transferring the t-bars is a pain because of the size difference as you mentioned, and the rubber is likely shot. The QA1 t-bars aren’t that expensive and are much closer in size to the fwd shocks, so you just have to press them in.

Yes, this is why this swap works - just need the t bars and new springs so the back end isn’t squatted

rockauto lists a few LESJÖFORS 4295810 and 4295811 (which is described as heavy duty )
No specs for either though or mention of what heavy duty means in this context



i might just leave the springs and see what happens. I'm running a 215/60/15 tire on the rear , i'll just swap a taller tire like a 235/ 75/15 if its too bad or learn to love that low rider look :lol:
considering i only had 1 semi operational nivomat beforehand it could be a wash all things considered

You need Lesjofors 4295858 for Nivomat delete. Neither of the springs you listed are even for AWD.

It’ll be too low in the back and you’ll rub tire on inner fender and you’ll rub tire on the brake lines. This will be far exacerbated with bigger tires.

Just do it properly. Not expensive or hard.

54 each on fcp auto. I see them now but the first time I looked only front springs were coming up over there for a V70

on that part the note says

Nearly All AWD P80 chassis vehicles in the US got Nivomats with potentially the exception of some S70's. This is the spring to convert to standard rear shocks. Ride height is denoted by rear spring spacer, not total spring height. Use only with standard shocks.

Which begs the question , what spacer are they talking about?

Could you start a thread on this and document the parts for the swap?

Just when I thought I was out of the AWD game, it sucked me back in….

I’ve never seen a spring spacer in any of these cars. Perhaps that’s the way you get the additional ride height for XC cars using the same spring? Not sure. That’s the spring you need, and will be the proper height on V70 when paired with conventional shocks.

Just for clarity’s sake, you have a regular V70 AWD or an R, correct? This will be slightly different on XC with its slightly raised ride height.

Everything you need is in my Emerald thread over on Swedespeed. Make yourself some dinner or pour some of your preferred drink first - it’s a rather long read, but it’s full of great info

Just a standard v70 AWD

Is this thing at the top considered a spring spacer? Its a solid inch thick plastic puck above the coil that doesn't really need to be there , at least in that thickness , protruding down inside is a hard plastic tube with a 1inch plus softer button bump stop thingie stuck on the bottom of it , intact on the driver side , snubber is laying at the bottom of the coil on the passenger side

Theoretically there could be different thicknesses of that part to change the ride height or be used for different springs . I don't see them for sale anywhere online , only spring "seats" which come up for front springs

I don't see rear parking brake dust shields available either thats unfortunate :?

I am off to a junkyard or 2 today for a VW cabriolet parts hunt I will try to look at a few volvos and see what spring setups they have.

I don't like the absence of spring details online. I like to see more than part numbers , or the words "heavy duty" . which means nothing to me. Free length wire size outer diameter. It wouldn't kill them to provide these things on the manufacturer sites at least .

All the AWD cars have that, and they’re all the same thickness as far as I know. I think you’re overthinking this based on conjecture from a single listing - I haven’t seen any proof of this so-called spacer existing. Ride height is set by the springs in the back for non-Nivo setups.

Some people with functional Nivomats used to lower the back end of their cars to match FWD lowering springs up front with spacers on the shock mount back in the day, so perhaps this is what they’re referring to?

I’ve been way too deep into my fair share of these things and can promise you there’s nothing to learn investigating the different setups with P80 AWD. There’s only 2 variations - w/ or w/o Nivomats. All US wagons got Nivomats from the factory.

Yeah, you can’t get them anymore. You can’t get much of anything for the AWD cars anymore, really. Hence the FWD swap being the way to go, and why this hybrid setup you’re making here isn’t the solution it seems since it’s still dependent on nonexistent AWD parts.

Some more detail would be nice for sure. Having done the digging, I can assure you that you have Nivomat springs and need to switch to the non-Nivomat variant, swap in some non-Nivomat AWD shocks, and call it a day

Dust shields and brake bs king plates for the rear awd have been NLA for a long time, I think Neil got some of the last ones
