So I just found out that my truck has got the zx3 electronic suspension. The truck has 127K miles on it, pretty much rides like ass regardless of whether or not the zx3 assist is on or not. Just curious what everybodys thoughts are on trying to get OE parts installed new or just use something aftermarket. Didnt actually even occur to me that I had it until i got under the rear and start unbolting one of the shocks when i noticed a plug going into the top of the thing.
