My air suspension consisted of:
1. Belltech spindles
2. SSC Two-link with a basic c-notch
3. Suicide door's front bag cups and shock relocator
4. Eight "aim" 3/8" valves
5. Four phoenix 2500 bags
6. 6 gallon tank
7. Viar 450c compressor
8. Aim digital back guage
This winter I'm upgrading to better 1/2" valves, 1/2" line and a engine driven compressor.My trucks pretty fast, but i need more air reserve and I would like it to hop. There is nothing like sitting at a stoplight and setting it down, people look at you like your crazy!! It will almost lay frame with a c-notch, I didn't want to lose my back seat or cut into the inside.

It almost lays frame, notice the detail??

Fast foward about six months and let me be the first to say.....bags sucks!
I had problems with leaks, keeping the ride height correct to maintain the front end alignment, kept blowing out my front shocks because of mount and postion, had to wait on the pressure to build up......I was constantly worried something was going to happen.
About two months before I sold it I switched to a static 4/6 drop with beltech spindles, coils , blocks,and leafs. This was the most I've ever driven since finishing the truck...it was awsome. ........I could get in this truck and go with no more worries.I'll never do bags again....
Here it is with a static drop.
