I just replaced both of my front struts on my 2016 GMC Sierra Denali 1500. I used the Arnott SK-3354 struts, they are suppose to be exact replacements according to them. I put these on and my truck sits about a inch lower now and side by side these struts are longer than the two I took off. I have Seen other post about having the (ride control) computer reset but I have called every dealership in my area and they tell me I am crazy there is no such thing. I must admit they may be correct but the sitting lower part has me puzzled.
