Hi I'm looking at purchasing a 3500 highroof EXT. The hesitation is I want to convert it into a passenger vehicle but would like to be able to soften the ride. I've tried looking for an air ride kit but it doesn't seem to exist. I assume because its a unibody. Anyone come across an aftermarket system. The Mercedes boys don't even offer any advice.
thanks in advance.

1109,
Might want to check out this link.
VB out of the Netherlands seems to offer the best air ride system I've seen, and Advanced RV seems to
be able to install them here in the USA.

See Post #9..... the Gliderite UK system looks quite good also.
Hope this helps,
Roger

We had a choice of representing the VB or the Glide Rite product. We chose the Glide Rite product because we feel the handling and overall performance is superior. For more info visit, http://sprinterstore.com/air_bag_kit.htm or contact us at 503-692-0846. Hope this helps.

Donít forget the upcoming SprinterFest East and West events.

Air bags are similar to rubber balls. The more air in them, the higher they bounce. Air bags will likely degrade damping, not improve it.

Koni shocks should help. Taking a leaf out of the stack would too. A one ton truck without a load will always ride rough. Wear a helmet if you are sitting behind the rear wheels.

The Sprinter 3500 has a base curb weight of 4,744 lbs. and a potential payload of 6,286 lbs. The suspension is designed for a near capacity load. Air bags ain't gonna do it.

Have any of you ever driven a Sprinter with the Glide Rite system installed? Cal? This is a completely different type of air bag system. It is nothing like the Firestone, VB or even our 2 bag system! If improperly filled, the above statement would be true especially with the 2 bag system. When set up properly, the end result with the Glide Rite product is a very quiet, smooth ride with outstanding slow and highway speed performance. The problem is the cost factor. The Glide Rite system is very expensive.

Anything for the 2500 2007?

No, haven't tried those bags. What can I say? Air bags are air bags. They have no, or extremely little damping qualities. John, does this bag have a piston damper inside? Where does the damping come from?

I did some suspension testing on my Sprinter MH (rocking side-to-side) a few years ago. I recorded G-forces with an accelerometer & then calculated the frequency and magnitude of the oscillations. I found the more air in the bags the greater the oscillation magnitude. Needless to say, they are no longer installed.

Our van is equipped with the Glide Rite system. The ride and handling are outstanding, imo. Also have Konis and a heavy duty rear sway bar; Alcoa wheels and oversize Michelin M/S2 tires. This system does not retain the OEM springs. It converts the suspension into a trailing arm system supported by two airbags on each side. The airbags carry all the load. A panhard link keeps the axle centered. It's a well proven suspension design.

One very nice feature is that it automatically maintains a set ride height regardless of load. (within vehicle limits of course) So as more load is added the airbags are pumped up by the on-board compressor to compensate. If the load is reduced, air pressure is released.

Every time we drive our van, my wife and I almost always end up commenting on how we like the ride.

The design of the bag, the bag base and the quality of the bag material can separate one bag from another. These are large Conti bags and the bag wall is a heavy material that offers stability and control. They are unique to the Glide Rite system and not available for purchase outside Glide Rite. A well designed bag and the unique spring that Glide Rite uses results in excellent performance. I donít have a pile of electronic analyzing to support the performance of the Glide Rite system. But I have driven hundreds and hundreds of Sprinters with just about every combination of suspension products, ours and others, and the Glide Rite system is right at the top of the list. We have input from customers and contact with people from all over the world and the word is that something about Glide Riteís 4 bag design works better than other designs. VB users have reported they converted to the Glide Rite system because the VB ride was to rough and bouncy. Most of these reports come from ambulance companies.

I erased my post because of the replies received already did the koni sway bar thing long ago.
I see that John and Roger get what i was after, thanks.

If you read the text below this youtube clip looks like MB will be offering air suspension on the 2014 3500 as an option, pretty smart.

This is closer to where I was going....

Air springs are indeed very progressive at high air pressures, more air you add more bouncy they get, but, at low air pressure they are almost linear. With an unloaded van and low air pressure they should be much better than not adjustable leaf springs set for a full load. The Glide Rite is using 4 air springs and this air volume will further reduce air pressure required even at higher load if compared to 2 air springs and I would not be surprise if they are indeed much better at full load than leaf springs.

I installed 4 air springs on the 2 axles Bigfoot trailer working in conjunction with leaf springs. At 15 PSI the suspension was much softer than just with the leaf springs as measured with accelerometer. At 30 PSI it was worse than just leaf springs. In addition I was able to level the trailer side to side up to 3” with air springs.

Inquired about both glide right and vb, both really nice, 5-6k rear axle only.

Standard is 35.25", dropped 6", 29.25" for the hi way, dropped 9" for parking only, rode and handled really nice like air bags do, that might be worth my fabrication time and money.
Only a 4 wheel full weight capacity system would be acceptable.

I already have a compressor and 3 gallon tank for my air horn. Feel free to laugh out loud.

To anyone with a Glide Rite Air Suspension on their Sprinter based motorhome, does the spare tire have to be moved with this suspension? Where does the spare live? Also, does the generator need to move from behind the rear wheels? If so where does it move to?

Thanks,
Henry
