I have an 06 GMC sierra crew cab z71 4x4. I was wondering if there we any lifts that are dependable. i dont do a lot of off roading but im sure after i lift it i will but i wont be beating the hell out of it considering its the only vehicle i have. I was looking for around a 4" lift and be able to fit 33x12.50 without the wheels ticking out from the fenders real far. I know that having a 12.50 wide tire will stick out its pretty much unavoidable but i want a lift that will be able to keep the wheels inside the finder wells. any input would be greatly appreciated.
