There is a brake line bracket on the driver side frame rail preventing the shock from being mounted right side up. These shocks can be mounted either way.
+1 for Dirt King. Their products and customer service are top notch. I only have their UCAs but, if I ever pull the trigger on a LT kit it will be dirt king for sure.
I am sure you have thought of this but, I was low on brake fluid and was having these issues. As soon as I topped the brake fluid off, issues went away.
I have a 2018 Silverado LT with 600 miles on it. Picked it up last night after having Maxtrac 5" spindles and 315/70r17's put on. On my way to work this morning my dash lit up and I got the following email notifications from OnStar:
A critical issue with the StabiliTrak® stability control system in your 2018 Chevrolet Silverado has been detected.
A critical issue with the Antilock Braking System in your 2018 Chevrolet Silverado has been detected.
The dash lights have since went away but, its concerning reading this thread.
