I want to get my truck lifted but are there any disadvantages (apart from higher centre of gravity) like would it weaken the structure or would it break more easily if i do a jump?
When you lift a vehicle you put a LOT more strain on the suspension especially ball joints, shock mounts, sway bars, tie-rods, and steering stabilizers. You'll wear these parts out a LOT faster, and your vehicle will get worse gas mileage, and the drive-train will have to work harder.
Drew doesn't know the truth...and why should he? He's, admitted, a parts changer, not an engineer. The structure of the vehicle is the same no matter how tall the suspension components are. The vehicle will break just as easily with or without a lift if you jump it, without building it to be jumped. Balljoints don't know how high the body of the truck sits. the drivetrain doesn't know how high the body of the truck sits. The driveshaft angles can lead to increased wear on U joints, but only IF the angle exceeds the factory recommendations. There are ways to change this, but it involves additional parts. You also didn't say how high you are talking about lifting it, and what you're lifting. Lift a Jeep 8', and you will wear out U joints on the driveshafts and really raise the center of gravity. Lift an F250 HD 4 and you probably won't see a difference in anything.
