I installed one set and it wasn't quite enough so I installed the other set on top of those and it made a huge difference with two. My question is if this is normal do to the angle of the ram or if ther my be a problem. They are only 3/4 inch thick but the second one limited the distance by about q a incnd a half of travel. And the trim only gets into about an inch of the trailer mode any help wold be great. Thank you
