I have the nivomat set up and altough it is NOT autoride, my shocks and springs are simlar to your stock setup. The coil springs for the nivomat and autoride are different than the regular suspension. This makes it impossible to run a longer shock with the stock coil springs. Long story short, the nivomat and autoride coil springs are softer and use a heavyduty (much stronger) shock. When you switch to a standard shock, the rear is saggy and bouncy. The regular suspension uses a stronger coil spring and a standard shock (less stronger shock compared to the nivomat and autoride). I have bought z71 springs and will be using 1.5" spacers and 5100 shocks.
Since you want to keep autoride, you can not go the same route I am. While researching options for my truck, I NEVER found a shock extender for the rear...for a lifted application. I found tons for the lowered. After more research I found there is a kit out there to retain the autoride and lift the rear to match a 3" lift. It is the skyjacker lift kit. It comes with shock extenders, longer control arms, and everything needed to keep your autoride. Downfall, its going to be about $400-500 alone for just the rear.
What I am trying to say is, if you want to retain autoride your options are to lengthen the sensors and try to find shock extenders or buy a lift kit that will work with it. THe other option is lose the autoride kit, buy some z71 coils, spacers, and shocks, and save a lot of $$.
****This is just my input, not saying there are not other options out there, this is just what I have gathered over the past couple weeks of researching.****

i too are in the same autoride boat. Im lookng to get the 3" keys 2" spacers w/ shock extensions from ebay, but am not 100% sure that
1. I can still use my factory air shocks
2. Do the extensions go on the front or back
3. Will the air shock life be shorten.
I think that when i get a little extra mula i will just pull the trigger on it and do a little trail and error.....hopefully with little to no error.
Will keep yall posted.
1. With the kit you talk about, you would need to run extensions to retain the air shocks.
2. The extensions with the "key/spacer" kits ebay are for the front. I have not been able to find any shock extenders for the rear with a lifted application. Most everyone just buys a longer shock.
