hi Dean,
ya, I put in lowering keys, but it is not really necessary. It sat too low with them (it was bottoming out on the bump stops). I have it dialed up to almost the stock location now.
I first tried to put lowering spindles on it, but those don't work for the '96 model year.
I do have small update on the Chevy..... I finally broke down and bought the LED lenses to put in the stock tail light housings. My wife was complaining that the lights were too dim and she was afraid of getting rear ended. I think she has driven the Chevy so much, she will be needing new tires soon.
Mike
