2006 Chevrolet Silverado Suspension replacement

[TNT2000]

I have a 2006 Chevrolet Silverado with the RPO code ZX3. The code is for the suspension package which is ride-control/ride control manual selectable.

 

I am on the verge of replacing the shocks, ball joints, steering linkage/tie rods/bushings. I am trying to find out what replacement parts would be correct to keep the electronic controlled shocks.

 

I don't need to keep that option but if I am going to eliminate that then I would like to know what issues that creates. I would also like to know how to fix any codes that would come up by deleting that system. 

 

My ultimate goal is a level kit, 2 to 2.5 inch front lift with all necessary parts replaced in the front end and shocks all around. If you know what suspension package I have on the VMAX then you know each shock runs around $250 which means I would already be at $1,000 just to replace all four. They need to go and I am looking for best viable option that makes mechanical and ride sense. Thanks all for the help.
