Hello there. I bought the Deaver 10-leafs and Bilstein 5160 for the rear. I love the ride. But I feel like needs a little more lift. I like the tail of the truck a little more raised than the front. And need some more clearance between the bumpstop and the frame. When driving at 40 mi/hr and pass over a bump, ford, or other noticeable road imperfections the bump-stop hits the frame. I know that is what supposed to do, but I think it is not normal at lower speeds (Never happened with my old 98 tacoma, or my camry). How can I fix that? What do I need to buy/replace? The distance between the bumpstop and the frame is 3 and a half inches.
