Air helpers in coil springs?

[olds vroom]

Has anybody ever used these airbags that go inside coil springs? I have a 41 olds that has the original coil springs in the rear and I think its a little saggy in the back end. What I'm wondering would these help lift it a little

I've used the helper springs inside of a set of coils - there's the adjustability of the air spring, but be aware that while you can effectively have a 2" adjustment in the rear ride height, the more air you put in the harder the ride gets. When I put in a set, I also picked up a controller; there was a pressure switch that kept the pressure between 10 and 100 PSI. At 10 PSI, the ride height and quality was the same. SO.....I ran it up to 100 to check the high pressure shutoff and took it for a ride.

I made it a block and a half before I let the air back out.

If I had a classic that had started to sag, I'd just put in new coil springs. Your back and neck will appreciate it.

my 55 buick came from the factory with them.

I'm not looking at helper coil springs but the air bags that go inside the coils. Or can anybody suggest a place I can get new coils for my car

Thanks hinklejd did you use any air pressure less than 100 psi and how did it ride?

[hinklejd]

I found a happy medium at about 40-50PSI, but I like a firm ride. The owner preferred less air.

Now this was in a Chevy Trailblazer where I installed a lowering kit and was going to do some towing. The adjustability of the air helper spring gave me the best of both worlds in that situation - I could have a smooth ride unloaded, then add air when the trailer was connected and not bottom out on every bump.

Anybody else have any experience with these?

Used them years ago in 67 Olds 442 worked good for about a month then one blew out from coil spring rub. If you can't find new coils,put some coil over adjustable shocks on it.

We have 'em in the front of the plow trucks where I work, they usually blow out in about 3-4 years due to the springs getting rusty and wearing through the bags. If you plan on using them thoroughly clean and paint the inside of the coil spring. At 60 psi they will raise the front end of a truck w/plow about 1 1/2 - 2"

Air Lift still makes them. I put them on a customers 69 SS Chevelle and he likes them a lot. I also run them on my shop truck. They work great for pulling a trailer or putting a load in the bed.

They aren't a life time deal, need replacing every 3 or 4 years.

I put them on regularly, for newer cars. In fact put some on today for a customers Rav4 suv. They are made by firestone, called coil rite's. OR made by airlift as stated.

They work good in stiffining the coil spring rate. They will raise the car a little but it is at a very small proportion to how hard the ride will be.

In other words they are more for stiffining the ride then lifting the car.

Durability would be really good for your application I think. The warranty on them is generally 2 year / 24K miles. I have never warranteed any.

Hope this helps some.

I have them on my '96 Caprice and my '69 El Camino, primarily to bring the ride height up to normal when hauling something heavy or towing. Had one fail from a manufacturing defect on the Elky and AirLift sent me 2 replacements free. Other than that, I have never had a problem with them. I like them.

Yes, as they raise the ride height they also increase spring rate.
