GMC Sierra 2014 Automatic Gasoline mileage: 300 KM or more 4WD Sierra model 14 flipped to 16. The body is fully cosmetically painted, and I don't see any putty in the body, honestly, I haven't inspected it with my own eyes. The engines are good, thank God. The engine has been changed, I installed an engine model 18. The reason for the change was for the lifters and the water pump of my Dinali. And the additions: King shocks with cylinders in the front and rear without. And it has an electronic kit. And a 40,000 transmission cooler. And a bed cover. And an anti-slip separator. And an ABS separator. And the four-cylinder has been canceled. And it has new Kuwaiti rims. And Shahin tires. Masha'Allah Tabarak Allah🤍
