Thread: EAS suspension gone, Yay!!

EAS is the business !

It's the best thing going for the late model Classics and only a HEATHEN would get rid of it.

People who convert EAS Rangies back to coils will be first against the wall come the revolution !

I dont think you can use the boges with heavier springs. I did have new OEM comfort springs and boge dampers all round, and it was perfect. But then I put manual airbags in the rear and I now find the car is nice but bouncy, the boges dont have enough resistance to stop the airbags, which are soft but powerful on the rebound, rebounding. So now I need to delve into the world of dampers and find some that give me the same soft ride with the airbags but also stop the rear wheels leaving the ground on a speed hump.

I think you will have the same problem I do if you put HD springs with boges.

I do not know.

I do know that the reason Land Rover fitted low rate springs was to reduce the speed of the vehicle deflection after hitting a bump. I read a technical article about Hydromat that detailed how a Hydromat enabled this to happen. The lower the speed of deflection of the BODY of the vehicle the more comfortable. Also why you get "head toss" much more in a Rangie with stabilizer bars than one without, as the spring rate of the bar is added to the spring on that corner when only one side hits a bump.

So I think that you will still notice quite a lot of movement when on rough roads which are bumpy/wavey. The Boges will damp out the low speed harshness of the Bilstiens, but I do not know how they will go at damping the quick oscillations of bigger bumps without overheating and fading with the very stiff springs. Boges will not recover like Bilstiens from overheating from corrugations.
If I had not been planning long trips over thousands of Ks of corrugations I probably would have stuck with Boges but my springs are a lot less stiff than yours.
To me a good shock is one that is unobtrusive, ie you really cannot feel the shock damping, but there are no secondary oscillations after say hitting a dip. My Billies are FABULOUS at this. I remember doing a Yump with the camper on at an unseen dip on the Kalumburu road. The landing was so soft that SWMBO didn't really realize we had been airborne, a combination of the progressive air bag rear and billies control.
