Gents -- I, too, have been a recent OEM "shock-ed" victim ... since there doesn't appear to be any bailout money available -- I couldn't find a cash-for-shocks program -- I have been looking for alternatives ... I came across a link that describes how the autoride feature can be disconnected/disabled.
Here is the link: http://www.fullsizechevy.com/forums/...isconnect.html
... if the link won't work, search the web for "autoride disconnect." (Credit goes to "Jacqson" out of Vancouver, BC)
The system is controlled by the SCM (Suspension Control Module) which detects body roll and suspension movement and adjusts the shocks accordingly. This info is also fed to the BCM (Body Control Module) which also monitors wheel speed, ABS and the EVO. The RPO codes (Z55 for the 2500; Z55 and/or ZK3 for the 1500) are input into the BCM which monitors all the functions of these 2 codes. If you disconnect the shocks or the system detects a voltage flux or change you get the light show on the dash. The Helms Manual states that if you replace the BCM you are supposed to input all your RPO codes into it. If you disconnect the SCM and then input all your RPO codes into the BCM except the 1 or 2 autoride codes the system shouldn't detect the Autoride.
In essence, if you take your BCM and re-program it without the autoride RPO code(s), your vehicle will operate as before (ie, no codes or flashing dash lights) and you can install any type of shock you desire.
Jacqson -- the author of the cited link -- indicates that for the 2500, it doesn't have the load leveling feature with the air pump, so disconnecting the autoride is no huge loss. If this project is done on a 1500 you will probably have to firm up the rear coils and definitely use a good set of monotube shocks like Bilsteins.
Jacqson also indicated that "after driving the truck for about a month now in different driving conditions including off road and there are no problems to report. The ride on the truck is a little smoother with the Bilsteins and everything is working perfect. The handling and braking have not changed and other than the better ride there is no difference in the way the truck works, except for the fact that when I need shocks I won't go bankrupt trying to buy them."
Finally, I have not yet disconnected the autoride on my Sub (I'm still researching this issue), so I cannot provide you with any data/experience(s)/etc. Should I move forward and attempt the disconnect procedure, I will let everyone know. Regards, Greg.
