Just installed the Rancho front strut quicklift assembly. Previously I had the stock struts with a leveling spacer and had no issue but the quicklift struts have raised the front a bit more and now it seems my upper control arms are hitting the droop stops. The ride is terrible. When I go across big dips it feels like a pogo stick. Will aftermarket upper control arms fix the issue or do I need to put the stock springs on the Rancho struts? 2017 z71 CC
I just had my truck in for a faulty fuel gauge. While in they did a ECM update. From what I understand one of the updates was to address rough idle. The update changed idle timing and swear I sometimes have to look at the tac to see if it is running. It's extremely smooth now.
Something I discovered recently. If you hold the tow/haul button for 3 seconds it will toggle on and off the grade shifting feature. Mine was on by default. I have turned off the grade shifting and have since noticed a significant improvement in transmission performance. Especially during deceleration. The clunkiness is almost completely gone. Give it a try.....
IS the truck completely stock? AFM on and no catch can?
Not sure if anyone else has this happen. When I use remote start the rear defrost comes on automatically. It doesn't matter what it is set to in the remote start settings. Currently I have it set to off but every time I use remote start the it lights up the button for rear defrost. I always have to manually turn it off after I start going. Sometimes I don't remember and it just stays on and I notice it 30 minutes later when I get home.
