I am rebuilding a a 2002 Eurovan and want to install a Firestone Air Lift 1000 air lift rear helper spring kit. The air bags are supposed to fit between the coil springs and give up to 1,000 psi to Eurovans for leveling loads while towing.

Here's my dilemma. The existing Euro coil spring does not look at all like the stock Eurovan coil diagrams or the Air Lift installation diagrams. I don't see how I can install the air bags without puncturing the bags. Is the thingy in the center of the coils a broken Bilstein-type spring and can I remove this and then install the air bags?

Looking for advice as to what to do. I can still return the air bag kit but really wanted them to assist for road handling while light towing.

The post in the center of the upper spring perch is the spring retainer and bump stop.

The only pics of Air Lift bags I've seen installed on a VW are for the Vanagon, and they appear to install within the spring sideways: https://www.thesamba.com/vw/forum/viewtopic.php?t=161643
If your instructions from Air Lift show a picture that doesn't look like your suspension, then I'd be inclined to assume you received generic instructions that go along with a generic/universal airbag.

FWIW, Air Lift and Firestone are not the same company. The Firestone Ride-Rite airbags have a recess molded into the top for the bump stop/spring retainer post; however, they have an issue with the air-fitting on the bottom getting tweaked and leaking air.

I don't think electrickery works that way

Yeah, I don't think those are going to work for a Eurovan.

In Europe they call a Eurovan a "T4", and this site has rear air springs for our platform that look completely different:

You'll want to look for something like this, or maybe see if they'll ship to you.

Thanks for the replies. Looks like the Air Lift kit is going to be returned.

Saw these https://www.airbagit.com/Air-Suspension-kits-Rear-axle-p/fbx-r-vol-56.htm These look like complete replacement of the rear coils, like those Ocelot linked.

And these https://www.sdtrucksprings.com/index.php?main_page=product_info&products_id=6722 These are Firestone and like other Firestone's I've installed you probably have to cut off some or all of the bumpstops/upper spring seat protrusion. Then you place those pucks in the kit on the top and bottom of each bag to prevent damage to the bag.

Maybe call Firestone and get the height/width of the bags to determine how much you would need to cut off the bumpstops/protrusion. Looks doable pretty easily, and cheap. On install I put wireloom on the airlines to prevent damage. Best of luck.

Anyone install these air bags and have an account. I have airbags in my truck and love them. Looking to add a set to the camper. I had adjusted the torsion bars so that the van sits level. However when loaded the rear really sags.

I've had a similar question about how to add more carrying capacity to my 2003 weekender. I pull a teardrop trailer from time to time. When we go for longer trips I can end up loading up quite a bit of stuff and it really compresses the stock springs. The air lift bags looked like a great and simple solution except it looks like they don't really fit. Also, when I was researching this I went to the Vanagon forum and the consensus there was that air lift shocks was the proper solution. But again, fitting them to the Eurovan is a challenge and would probably require providing specs to a distributor and hoping they can match the right shock to our needs. I couldn't find an off the shelf solution with the air shocks.

So, I ended up putting in heavy duty suplex springs from busdepot. I just finished the install and it was a breeze to do. It adds height and my only test so far is to stand on the rear bumper. Definitely stronger than stock.

Here is what I ordered from busdepot: https://www.busdepot.com/j12985

By the way, I removed my cavevan spacers since these springs raise the rear plenty. I have a few upcoming trips and I'll add a photo fully loaded so you can see.

Looks like those springs are working for you.

I like airbags due to the variable spring rate. Right now our van is sitting level. But fully loaded I am guessing that I am putting 1200+lbs in there, with most of the weight in the back. I do not think that I want to drive around with the springs set to carry that load when empty.

Last summer I hauled a few yards or gravel in my truck. The gravel yard is close by so I made a few trips. I inflated my tires and airbag to the max. at the house and drove empty to the yard. Felt like I was riding a "hardtail" with stone tires. Loaded up however it was a pretty cush ride.

I'm not sure they are yet. I really liked the ride with the OEM springs when the van was unloaded. I only need the extra support when loaded up. You have made me rethink this. I'll keep my OEM springs and spacers. I have some trips coming up this summer with a fully loaded van. The suplex springs are supposed to be progressive but I've only put about 50 mi unloaded so we shall see

What brand air bag did you go with? Any installation issues?

I have not bought airbags for the van. Just trying to learn.

For my truck I have firestones. I have beat on them pretty hard for 10+ years and they have held up great. My heaviest load was 3000lbs of gravel with the bags at 100psi.
