When I had my last 940 a couple of years ago I bought these but never got round to fitting so passed them on the the new owner when I sold the car-

Seemed good value. My current 940 has new shocks and springs all round fitted by the previous owner so can't bring myself to fit some new springs when the existing ones are like new!

Chances are, the old ones were weak and while they controlled the old, weak springs ok, they couldn't cope with new springs that were stronger.

Coilovers can be good if they're set up correctly but tend to be more difficult to get the right mix on both to work right, especially with "universal" kits.
Actually Dave, the dampers were brand new GAZ fro a well known supplier...i don't think the kit was especially researched / developed and therefore matched.....because i fitted both at the sametime it was impossible to tell which was at fault.....The ride was rubbish though...and i have lowered in some way every car i have had since age of 19!!!!!
The Bc coilovers were a MASSIVE improvement over the Kilen/GAZ setup!

So you don't know what was at fault but blame the springs as rubbish anyway?

Volvo 940 springs are linear rate springs, as long as you fitted the right ones it would have been fine - probably the shocks at fault (faulty or wrong ones) or wrong springs.

My 40mm springs and B4's work very well, more controlled ride, yes a little firmer but not uncomfortable and handles a lot better.

The dampers on my 940 were so bad when I bought it the back end used to bounce up and down after a speed bump so long they were still bouncing at the next one - had a look at them when they were removed and one was barely working and the other had zero fluid/gas left in it and was just two tubes sliding in and out of each other! Was a revelation when the full car setup was replaced.

That pretty much describes the state of the Nivos on mine when i first got it. As they also control the ride height, the back end was about 40mm low and very soft. As a result i ripped the exhsut off on a speed hump.

As i said, i was unsure which were to blame. It sounds like it may of been the dampers judging from your experience. With the GAZ/ Kilen setup you could feel every little ripple in the road too, i just didn't like it. It would of been nice to try some different dampers but i decided to go with the BC kit instead and really glad i did....

I've got Suplex springs all round on mine, standard height (and see my note about Suplex/Kilen/Lesjofors above) and KYB dampers.

Extremely smooth, balanced with no undue bounce or anything. Many people who have ridden in my 32 y/o Volvo think that it rides like or better than a brand new car.

Leads me back to what i suggested about the dampers and also what Rob suggested along similar lines. If the dampers and springs weren't a well researched combination that wouldn't have helped, it's possible they were standard dampers and you'd fitted them with uprated, lowered springs in which case they would perhaps struggle to react to every little movement. Were they adjustable at all?

The common complaint I here with BC's is the rear end is terrible, you see the same complaint often with them for both 240 and 7/900 series

https://forums.turbobricks.com/showthread.php?t=354642


the reason is the wheel rate ends up with the rear being nearly double the stiffness of the front, the opposite of what you want for driving

I suspect but can not confirm that perhaps short GAZ dampers were used with 40mm lowering springs where they would need to be full length. Otherwise could simply be the dampening adjuster were just not set in the right kind of area

Would springs and shocks from another model fit and would estates and saloons be the same

All the 7/9xx springs and dampers are esentially the same, however there are a few discrepancies.

For example, any saloon with IRS/multilink rear suspension uses different rear springs and dampers.

I'm not aware of any models that use stronger springs as standard but i believe some models were available with stronger springs on the back end (Business pack or tow pack?) and i suspect the D24 engined models have stronger front suspension due to the engine being heavier.
