I agree with Mark.You have Z55 Autoride and G69 auto leveling which means air bladder shocks on the rear, self leveling. Those rear Bilstein won’t work. I don’t believe Bilstein makes a direct replacement for the rear if you want to keep the self leveling. Read what @iamdub said above but keep in mind its easiest to keep the system and imo it’s worth it. Expensive to maintain? I have replaced my compressor and shocks with Arnold products and it wasn’t that expensive honestly, plus they have a lifetime warranty. I love being lowered and still be able to tow a heavy trailer and it automatically keeps the rear leveled. Removing the system can be a hassle also but it’s not that hard if you know what to do, there’s plenty of info here as well as experienced people to help you. First, you need to figure out if your compressor and rear shocks are still working.
My first choice would be to keep the ALC and go with Arnott products. I believe you will need AS-2700 (new) or AS-2708 (rebuilt). Have had good luck with both. If your compressor is. It working, their compressor is quality as well.
