So first, to the person who says you're feeling more through the wheel and it's a rougher ride, YES! If you put the fronts on without reading what these are it's your fault. The fronts are lifting shocks and these are more meant for severe duty. I'm also willing to bet you have the 3.6 as the Hemi will put more load over the fronts and make it less harsh.The rears are a masterpiece and quieted down my ride, improved the ride dramatically and removed lean in the corners. It also made towing my toys around more comfortable. I will not be using the front 5100s since I don't want to compromise my ride nor lift the front of the jeep. Instead I'll use the 4600s which are a 100% stock replacement with no lift and a magnificent ride. It's okay to mix and match and in this case I recommend it to everyone even if you don't tow. The Jeep nor rides as well as my 300c show car did with airbags and that's saying something.
