I’ve got 3000 km on my 2019 z71, it has a levelling kit in the front and 275 70/18 BFG KO tires. I travel off road to a hunting camp, on a extremely ruff road, the truck drove well new but now it’s all almost hard to drive at 80 to 100km down some of the country type roads, truck is floating all over the place. I think the shocks are gone, maybe hydrolocked or something. I’m just debating taking it to the dealer, or just buying new shocks. I’ve only had the truck 7 weeks......I,d like to hear from people that installed the Bilstien 5100 shocks and what they thought of them.
