I was debating on buying any of these helper springs or airbags. I like the airbag ideal, but I have a 4"lift and I looked at the design of the air rite, and you will have to get longer bolts, and will have to modify the metal bracket that sits on the axle. I looked at a diagram of the air lift and it goes off the lift spring so it should be an easier install, but it doesnt look as heavy duty as the air rite. I will towing our trailer with band gear that has toung weight of about 1500 to 2000 lbs.

Any advise would be greatly appretiated.

 

I tried the Airlift on my '04 4x4 (Daystar in front) and found it to be perfect for my needs. That is, leveling the truck with a load(camper shell , gear, and motorcycle). Just let almost all the air out for unloaded conditions and up to 100 psi for full loads. 60 psi worked for me most the time. Never leaked at all in two years. I ran the dual valve set-up(manual) vs. the automatic($$$). A couple of schraeder valves poking thru the lower mounting holes of your license plate is the way mine was installed. I plan on installing the kit on my new '07 soon. Hope this helps you.

 

Thanks JDFITZ I think ill go with the airlift to. Thanks for the advice.
