Guys that are putting together homebuilt front leaf packs: I picked up a set of 4" pro comp yj lift springs, 5 leaf front pack unfortunately but the price was right. I'm going to pull out 1 leaf before I even put them in my 4runner, which leaf should I take out? Longest one, shortest one or one of the middle ones? I'm assuming the shorter leaves contribute more to the stiffness of the spring than the longer ones right? What makes for a good flexible leaf pack? For the rear I've already got the Chevys sittin in the shed, mounts welded to the frame, just waitin for some warm weather to throw em in. FYI $34 Canadian currency at Pn'P which is about 20 bucks USD.
