Has anyone on here ever tried these? I read on Jeep forum their noticeable on Grand Cherokees. I know my truck accelerates real well at half throttle but at full throttle from a stop it's real sluggish till about 20mph or so and I can feel it constantly pulling till I let off. Just curious cause I've never seen them before. How about a couple of you guys go get one and let the rest of us know how it works out.
