Since I leveled my truck last summer ive been wanting to lift the rear end a little bit so that when i tow my four wheelers and boat around it wont be sagging in the rear. So ive been looking at either replacing the stock lift block with a bigger one or buying and add a leaf kit. What do you guys think? Is there a brand that is better than the rest? Is installing an add a leaf an easy task or is it pretty difficult, Ive never tore apart a rear suspension before.
