My F150 was primarily used to tow horse trailers when it was new. The origional owner had Add-A-Leaf springs added to the rear. Currenty one front strut has gone bad. On 1-20 the thing beats you up. This got me to thinking about a full suspension upgrade. It didn't take long before I was looking over different air bag systems. I have 3 goals for my new suspension.
1) Improve ride quality
2) Auto leveling for towing
3) Able to drop enough in park to allow removing the running boards
- The driver seat needs to be as close to hip height as possible.

Notching the frame is not something I want to do, but the idea of a multi-link rear suspension is appealing. What systems have people tried on our type of F150, and what were the results? Has anyone built a system that does what I am looking for? Right now I am in the learning stages, so any info would be appreciated.

 

Take a look at Firestone Air-Rite™ system:

or www.airliftcompany.com. I was looking at the Load Lifter 5000 for my F150.

 

I am looking for a complete front and rear bag system, not just a load assist system.

Easy street only has front bags for GM trucks.

Firestone does offer a full suspension system, but they give no details of the range.

This is the closest pre fit system I have found yet.

I really like the option of auto-leveling. One thing I have to figure out is making the truck lower automatically when it is put in park.

This might take care of all my issues. In full down the frame can rest on top of the axle, so I don't have to notch the frame. I figure if I used some dropped spindles in the front I can get the seat hieght in the right area. It might look funny, but it would be easy to get in and out of.
