Thread: Air to coil springs

Just google range rover coil spring conversion and start from there regarding costs, vendors etc,.

I have a feeling that it may be 'technically' illegal in some eastern states,,,

- The dampers (shocks) for coils are differant to those for air-springs. You will have no self-levelling unless you install some airbag-inserts into your rear coils... or find a working Boge self-levelling thingy.

Hello well after doing it i don't know if its the right choice. Very easy do do
for any back yarder with a few tools who,s keen enough.
I used all the suppliers rover craft ,brit parts and auto line gab a manual or print something off the net or you can even buy a complete kit from various places .But regardless of what people say about caster correction you should do this whether its slotted balls or replacement bushes for a two inch lift and you will need airbags in the rear springs to stop the saggy bum when you put a carton of beer in the back.
The long story is if i was not going to remote places i would never of done it.

And here's me wanting to replace the coils with air.

Yes, YES, - Do it! - why should I be the only idiot who re-furbishes his air suspension...?

Was following a nice Defender 130 with air suspension a couple of weeks ago.
My two Mercs both have air suspension. Nothing rides like air.


I wonder what is involved in converting it?
What are you doing with the old bits you take off John?

I was collecting parts to do this when I stumbled across a 93 with intact air suspension, the body colour and interior I wanted all wrapped up with low km's, good history and enough recent burglary damage to scare off all other buyers. Twas a good day.

Anyway.
Front shock mounts to the axle casing are the major change. Everything else appears to be pretty much a bolt-across. You will need chassis brackets for the height sensors and mounts on the suspension links. But they are minor compared to the front shock mounts.

Then it's just a wiring nightmare.

My (fading) recollection is that the old (89?) Classic on springs/Boge/Firestone coil inserts at 12psi was smoother over the lumps & bumps than my '95 on air.
Certainly felt fewer and less of the smaller road imperfections... or maybe stuffed dampers.
Don't think it had both sway bars either.... rolled a lot even in the car park.

But I'm happy with my EA$.

The original classics on 130 lb/in springs were very soft. I run 180lb/in in my diesel classic and it's not a limo, but still very good.
My EAS classic is firmer, but I have a plan to fix that. It involves plumbing an air reservoir in to each corner to increase the air-spring volume and decrease the spring-rate.

Just got a thousand other things to do first.
