Air ride shocks

[Tahoeelf]

Hey guys new to the fourm. I just bought a 02 tahoe 5.3 lt. I need air ride shocks. I got a quote at auto zone and they are not cheap. Does anyone know of a Web site where I can order them cheaper?

Thanks in advance

Has anyone used or bought an OBD reader capable of reading C codes like c0660 for the autoride? My current OBD reader says no codes but the indash message (service autoride system) is still there.
I replaced the shocks and I can bypass the relays making the pump run but it won't start or run by itself. Just looking to fix what's wrong and not parts that still work. I'm tired of guessing.
Any help greatly appreciated.
Thanks
