I am wondering if anyone has replaced there rear springs with a full air ride system or kit. not helper air bags. I have been looking at Kelderman, and Road Tamer by Air Lift. i did a search but didnt find to much info, and the search function wouldnt let me go past page 14.
The reason i want a rear air ride is to get rid of the choppy bouncing i get here on Michigans crappy roads when unloaded, and to keep the same rear ride hight when loaded. well let me have it.

 

I installed a complete airbag system (not helpers) in my fathers Nissan Patrol (similar to reg cab F250 in size)
The ride was unbelieveable.

Though do yourself a favour and get some good monotube shock absorbers when you do it (Bilsteins or Edelbrocks)... I went for the cheap option initially (and got some cheap twin-tube shocks), but then installed a set of Edelbrocks.
WOW. The thing road like a limo - whether it had a load or not. And being able to back up to a trailer with it lowered - raise the suspension and drive away was cool too!!!

 

thanks for the info bigf350, i already have some bilsteins which have helped out alot. just need to do a lot more research before i get a kit.

 

A guy that works with my friend did an airride setup using semi bags. They did the swap at the shop where they work. It's not a 4x4 shop or anything, they maintain a fleet of heavy vehicles.

It is sweet, rides great. He has his hooked up so it will raise all the way if the alarm is armed. Raised all the way it could clear 44's pretty easily, he runs 40's. He also has sidewinder steps, so you'd probably need a step ladder to break into that truck.

They took alot of ideas from Kelderman when they built it.
