I am planning to buy a suspension lift kit for my 2003 Chevrolet Silverado 1500 LS. What brand can you recommend? I would like to add at least 4-inches of ground clearance on my truck.
technically, 4" more ground clearance could be achieved with 2" of lift and 2" taller tires or 1" lift and 3" taller tires or as @barrrf said, 4" taller tires and no lift edit: I also forgot 4" of lift and stock tires or 3" of lift and 1" taller tires
2" taller tires only gains you 1" of lift. So I was wrong. Under the rear diff ground clearance doesnt change no matter how much lift you put on. Right?
right. only the tires/wheels would change difference under the rear diff unless you swapped out rear ends, but wont gain you much.
