Full air suspension kits

Does anybody make an air suspension kit for our trucks? I already know about air helper springs and I don't mean those. I'm thinking of something similar to what ram is going to start offering on their 3500 trucks next year. A full kit with front air bags as well would be pretty neat.

After a while more of searching, I found Kelderman suspension systems. Does anyone have any experience with these or with any other full air systems?

Kelderman is top of the line! Very nice kits, I've never used them but they have won at sema...

I found this post on DTR:

I own a truck with a Kelderman air ride suspension and one with a Thuren Fab suspension, so I can give you an honest opinion of both.

The Kelderman does ride a tad bit better than stock, but for the money it is not what you are looking for. It is not hard to install, but it does take a couple days to complete because of the air system. It also has the inherent problems associated with an air system...leaks, freeze-up, solenoids sticking, etc. If I were to do it again, I would not do an air ride. Don't get me wrong, it is cool and all, but its too much of a hassle and not a noticeable improvement in ride.

The Thuren Fab suspension (Coils, Full Leafs, 2.5" King Shocks, Control Arms, etc.) is unbelievable! It rides better than any truck I have ever been in. I drive a lot of rough roads and it just floats over the big bumps. Everyone that rides in my truck comments on how well it rides on rough roads.

Go with a Thuren Fab suspension, or something comparable from Carli suspension (2.5 or 2.65 systems) and don't look back! You will be amazed at the difference.

Just my $0.02

Anyone have anything to add? Maybe Kelderman is not that great. My main concern is ride quality.

I put on a carli pintop system with their full rear leaf pack upgrade and love it. Ride quality is awesome. Kits been on for over a year now and been enjoying every minute of it. Money well spent

If you want a show truck that just gets loaded and unloaded off the trailer and goes to truck shows I would go for any of the front air ride kits out there. If you want to actually drive the truck daily and use it I would skip an air ride for the front of the truck. Just do the rear of the truck. They don't drive that great and honestly I know more people just trying to get rid of their kit off their truck. They don't drive like a dream like everyone says. They are a high maintenance kit and mainly for coolness factor. Remember that your steering wheel is going to rotate as you raise and lower the truck.

My friend has a full air ride setup for the rear of his truck and coilovers up front from One Up Offroad. It can tow whatever he wants and still drives awesome. If you are looking for a kit that you can drive down the freeway, go out and play at the dunes, and tow your trailer home. This is the type of kit that you should look into. This is a dodge but the same thing can be bolted to a Ford. It will drive like a freaking car and everything works.

Most people looking at "Air-Ride" kits equate them to short travel insanely soft bags like what's used in a Lincoln. This works OK in a short travel application because they don't support much weight but pressure (equates to spring rate in bags) rams up exponentially in very short distances. Regardless, this nets you very little travel when used as a primary spring (rather than auxiliary load leveling), especially when we're talking a bag heavy duty enough to support 100% of the weight and payload of these 3/4 and 1 ton trucks.

As already stated, a system like a pintop 4.5" from us doesn't reinvent the wheel like air-ride suspensions do, but completely redefines the purpose and capability of the factory suspension design. Let me know if you have any questions on our kits and I'll be happy to elaborate.

Good luck with your build!

First off, I'm not interested in lifting my truck because I like the ride height stock and most of all, I don't want to loose mileage. I realize that with the stock height, there isn't much room between the front axle and the bump stop and this really limits off road performance. With all this in mind, I could tolerate the 2.5 inch lift in the front if I have to.

The main thing I'm trying to get out of my truck is a good ride on concrete highways, rough asphalt, and washboard dirt road. I want to do this WITHOUT lowering tire pressure. Is this possible?

I don't see how I can get a better ride without replacing the rear springs with softer ones. How does a carli suspension on an F350 compare with stock suspension on a half-ton tuck?

For what you're looking to do, you would be getting a minimum of 2.5" of front lift and 1" in the rear. You cannot even compare a straight axle suspension to a IFS as it will always have more body roll but can be equally as compliant. You're going to need to give up towing capacity for maximum ride quality (full rear spring replacement). As for tire pressure, the ride will be better but until you run a larger e-rated tire with proper pressure, the ride will still be stiffer than it should be.
