I'm looking to buy some LC coils for the rear of my 3rd Gen 4runner but I don't know which ones to get. I would like to get 3.5 to 4.5 inches of lift. Can you guys post some info like year, color codes, front or rear coils, and most helpful Part Numbers please. Is is true that I should get 2 lefts or 2 rights so they are the same lenghth? This seems to be a confusing subject since 3gens and 2nd gens use lc coils.
