Air Ride

I'm in the process of building 4-link for my '08. I was building it for my '99, changed some things for my '06. Sold it and bought an '08. Maybe I will actually get it done before I get my next truck :lol3:

I am always looking for suggestions, ideas, tips, hints, etc.

Only have the front's done. Everything else is measured three times, and drawn out for a fabber to cut. I will tack everything and have it all professionally welded. My little Mig doesn't do it.

I'm using Firestone 2107s, 3500 pound capacity, 9" max diameter. Lift is 4" overall, with 2" extra in front to level it out.

Front right side view

Bottom-The two tabs will have a hole drilled in them and will mount in the lower shock mount bracket.

Top. The space with the machine nut is where the stock upper spring mount will sandwich between the new upper shock tower and new upper air bag mount.

Just sharing. But it's nice to hear other people's thoughts or ideas for it. :)
After looking at these lift kits and such I am wondering if my upper shock bracket is too tall. It's not much longer than the stock shock tower, but that is recessed in the fender a bit, and my shock tower is out a good 5" from the edge of the stock spring perch.

Is that upper mount tubing or is it just two flat pieces? Looks to me like that may be a weak link. but I always over build everything.
Yes, it is flat. But it is also 1/4" thick bar stock.

Also, there is 2.5" of joinery on each one, so technically 10" of welding to be done.

At least it's just a shock mount :T:

But this is the stuff I like to hear, constructive criticism and questions :thumbsup
What is the suspension travel?

Do you know how these bags ride? I have Pacbrake bags on the rear of my truck and I hate them. Due to the tiny volume of air they hold their springrate changes greatly with small deflections. This causes a pogo effect on speedbumps.

Can this be done so that there is only 2 inches of lift at the front and no lift in the rear.

Basically I am looking for an all airbag setup that only levels the truck.
Travel is 10 inches. Ride height is 10.5", almost dead center.

2" of lift is doable but I am not 100% sure due to measuring for 6", not 2".
