    I'm leaning towards the passive shocks, but the rear sag has me a little worried.
    I understand what you're saying with it only being $50 or so out of pocket, but the sag in the back looks pathetic with my 2 12's in the trunk.

    The ELC won't pick the car up of there is any sag?
    I assume NOT since the car wouldn't have air shocks. Basically I would have a new ELC installed and never use it, if I installed the passive shocks, correct?
    I don't think that is what he said or meant. If you use the PASSIVE shocks, you will STILL HAVE the ELC capability. Passive or nonpassive are a different function of the shock. Passive shocks are available with the bladder to make the ELC function work, just what Ranger and basscatt tried to explain to you. This is what you have now...notice the electric wire harness.

    http://www.rockauto.com/catalog/moreinfo.php?pk=95712

    These will give you the ELC function you need to keep the rear from sagging, but you will have to get the kit or use resisters in the electrical harness to keep the dash light off. Shop around or use the link basscatt provided to get the best price.

    That would be a waste of time and money. Those shocks are 10 years old and who knows how many miles are on them. Used shocks = bad idea.

    The resistors go anywhere in the damper actuator circuit. You can install them at the electrical connectors in the wheel wells, or in the trunk at the CVRSS module. A package of resistors is $1.19 at Radio Shack, you use one per corner. No need for a "kit". The rating you'd need is 1/2 watt, 4.7K ohms.

    Re: 2002 DTS rear shocks $$$

    your car has ELC - Electronic Level Control -

    the ELC system consists of several parts -

    a compressor assembly -

    a level control switch -

    air lines -

    and air shocks -
    the DTS original air shocks are ACTIVE -
    the base Deville and DHS models air shocks are PASSIVE -

    lets say you have a properly working ELC system -
    and you have 3 big fat people in the back seat -
    and 800 pounds of stuff in the trunk -

    the rear end will be sagging - due to the extra weight -
    as soon as you turn the ignition key ON -
    the level control switch tells the compressor assembly to turn on -
    air pressure is delivered - through the air lines - to the air shocks -
    and raises the rear end - to a predetermined height -

    now - lets say you kick everyone out of the back seat -
    and remove all the stuff from the trunk -
    the rear end will be sitting WAY too high -

    the level control switch tells the compressor assembly the rear end is too high -
    the compressor assembly opens the exhaust valve -
    which is built into the compressor assembly -
    and releases the "EXTRA" air pressure -
    allowing the rear end to return the the proper -
    predetermined ride height -

    BOTH the expensive ACTIVE air shocks -
    and the cheap PASSIVE air shocks -
    will work PERFECTLY with the other components of the ELC system -

    I hope this clears things up for you -

    It does clear things up for the most part.

    There is an air line that "plugs" into the active shocks. Can I plug the air line into the passive shocks also?

    The air line is for the ELC function, NOTHING to do with active or passive.

    YES

    and the cheap PASSIVE air shocks -
    will work PERFECTLY with the other components of the ELC system -


    they both REQUIRE the air lines - because they are both air shocks

    and the original air line will plug right in - without any adapters -

    I'll try to make this as simple as possible:

    If you want to maintain BOTH CVRSS ACTIVE SUSPENSION AND ELC FUNCTIONALITY, you have 2 choices.

    Ac Delco:

    Left - 580130
    Right - 580131

    Monroe:

    Left - 40029
    Right - 40030

    If you want to FORFEIT CVRSS ACTIVE SUSPENSION, and RETAIN ELC FUNCTIONALITY, you have several choices. Most everyone here will recommend Monroe Max-Air passive replacements.

    Part# MA822, same for both sides.

    If you go passive, you will also need a package of resistors from Radio Shack, model/catalog# 271-1124. $1.19 for a package of 5.

    Monroe MA822 Passive (air) shocks. Note the air filling near the top (it's capped for shippment).

    CVRSS
    is the correct/technical name for the ACTIVE air shocks -

    You guys are awesome!!!

    I'm sure you can tell I'm NOT a car guy by any means.

    You all have answered all my questions without getting frustrated.
    I can't thank you guys enough for all the kind advice.

    After all of this, I'm going to save some $$$ and get the passive shocks.

    As far as the resistors, where do I put them?

    you will see an ELECTRICAL PLUG - on the top of the shock -
    not the air hose - an electrical plug -
    unplug it - fold the 2 ends if the resistor down -
    and plug the resistor into the electrical plug
    that you unplugged from the shock -

    this "fools" the suspension computer
    into thinking the ACTIVE shocks are still connected - and working -

    if you don't use the resistors -
    you will get an error message on the dash that says -
    SERVICE SUSPENSION SYSTEM - or something like that -

    Be sure to make some type of water tight seal when you install the resistor.

    ABSOLUTELY A MUST -

    heat-shrink tubing would do nicely -

    Re: 2002 DTS rear shocks $$$

    alternatively you could canibalize the connector on the old shocks

    cut them off from the old shocks then wire in the resistor as if it was the shock
    that way you can do a proper soldering job and use a good heatshrink tube to keep the weather out

    this allows you to simply plug the two plug ends back together and if in the future you or another owner wants to get the car back to active suspension it's no big deal to just unplug the connectors
