Come along with NORCAL SS on a Lowering escapade on a 2011 Tahoe.

Also, do you ever tee both air lines together to use one fill valve so the bags fill evenly, or is it best to run each line individually with two fill valves so you can adjust each side independently?

You should always run the bag independently of each other. If you tee the fill line then when you turn the weight of the vehicle will push air from one side to the other which is not what you want. If you have to run a tee, the you need to put a shut off valve on each side. You would open the valves, fill the bags, then close the valves.

The very first picture in this thread should give you an idea of how the coil sits in the spring perch and where the line goes up the center and in between he frame and body.

Hope that helped

My question is. How much does that bag help? It looks very small.

Nice job Tony

Thanks, man. That first pic made it perfectly clear. After lowering my truck TWICE, I never played enough attention to notice there was a hole in the center of the upper spring perch. Lol.

Ah, makes sense. Never thought about the air going from side to side as the weight shifted.

Great glad it all came together for yah. I love doing things twice, haha. I did my previous Tahoe twice, my truck before that 3 times(lowered it, lifted it then lowered it again) I'm just a lowered kinda guy. Hopefully sooner than later my 07 will be lowered, with the help of someone here (cough tony cough cough)

Agree about the air valves being per bag.
