Air Bag suspension on '78?

<< < (3/3)

MADVET:
If you have a look at a typical air bag suspension you'll see that the air bag itself needs quite a bit of space. It needs as much space as a typical coil spring. While you might be able to adapt something for the front of a C3 the problem would really be the rear. After you have removed the transverse leaf spring the only place you could mount the air bag is where the rear shocks are mounted and really there is not enough space for them to fit remembering also that as the air bags deflate their diameter increases making the situation even worse. The only way to fix it is to re-engineer the whole rear end so as that the air bags could fit.
So unless you've got the bucks for that nice big bill i would still put it in the "to hard" basket.;--

77CVT - well it's a 78 so it's got the big boot. even with my sub install i should have plenty of room

MADVET - yeah see your point there. i heard that the read end would be the challenge in the project.
So what do people think of my other idea? anyone know of anything similar that's been attempted? (as in, the hydraulics/pneumatics to force the chassis off the axles, just long enough to get over gutters or speed bumps etc). Would it physically be possible?

MADVET:
You could try doing the air bag to the front only as it would probably give you enough clearance to get over most things. I recall that the Lambo Diablo had a similar sort of system.

Mattrix:
ah yeah. that's definitely an idea. so is there a kit that might adapt? i know that they make them for other chevs of the same era...
