95 caprice rear coil springs

[94HeavyChevy]

thanks to all for the assistance. I am going to go with moog rear coil springs for now and see how much that helps. If i need something further i will have to decide between the air lift bags or the air shocks. still not sure which to go with but both r around the same price.

Duane,

Firestone air bags really aren't modern technology. They have been around since the 1950's and used in a lot of applications. I had an industrial application that at last check was still using a pair of Firestone air springs installed in 1958, working 3 shifts 5 days a week to lift and lower a roller conveyor about 250 times an hour.

I also prefer the bags over the shocks since they place the strain right on the spring perches and axles where it belongs instead of the shock mounts. Air shocks are a quick solution and may be acceptable for light loads but usually compromise the dampening to something more like a taxi or truck.

Proper shocks for the handling and the particular feedback you desire (compression and rebound damping rates) can be installed independent of the bags to provide the best of both worlds. It costs a bit more, but has some advantages.

I didn't know they had 4L60E transmissions in 1969. Odd.

not much different in basic mechanical operation...only difference is the 4l60 is less reliable/has more controls..

how about a CVT in this ? I have driven these vehicles with the CVT up mountains quite impressive performance control at high speed with grades, steep grades..smooth very smooth..

Dude, the 4L60/TH700R4 is a 1981 design, where do you get this info? It has a TV cable, that's more controls? It does not have a vacuum modulator (like the 1969 design TH350 does). It is metric engineered - nobody (save for science) did metric in the USA in 1969.

still the GM trannies made in the 60's to 2011 still involve the same mechanical operation/function ...

gm is old technology..

these old gm transmissions are just updated clones !

Correct, GM is old technology.

JC,

Wait until you rebuild a CV box. They have been around in industry since the 1920s. They are commonly called "varidrives" if they use belts and "P.I.V.s' if they use a chain. Almost all of them are crude, less efficient, and not as forgiving nor robust as clutches and gears. I've rebuilt several in gear hobs and shapers. Lately, they have been getting replaced by servodrives which perform about 400% better overall.

CVTs are interesting, but not the ultimate answer. Look at the resale values of vehicles with CVTs. Servomotors at each wheel would be far superior in so many ways. Until you buy a Chevy Volt, stick with a geared transmission.

I wonder how many recalls on this project ? If I were in space out side of the space station , would you trust this GM product ?

Only if they send Mr. Goodwrench to fix it when it breaks..

Yes. GM played a large part in the Apollo missions that landed man on the moon.

If you're so worried about how many recalls on GM products, go get yourself a Toyota. Or, not.
