Very disappointed with this purchase. All online sources including Revain show this to be the damper that fits my 02 Dodge Ram 1500 Quad Cab 4x4. I even confirmed that with Bilstein. I scratched my head trying to figure out why installing this shock felt like trying to squeeze 10 pounds of sugar into a 5 pound sack. To install. I've installed several shocks in the past and never had much trouble getting them back in place. I was so confused about this I checked the numbers on the box and shocks thinking I had mixed up but all the numbers are checked. Now when I have cargo in the bed of a truck and hit a decent bump in the road, I can hear and feel the bumps bottoming out. If I had to do this over and over again I would choose the 4600 series or another brand. These shocks keep my 1500 handling like a 3/4 ton truck and do no better job of handling load, load sag or ride quality than a worn out Monroe Reflex that has come loose from the truck. Notice how intricate the trunk is in the second picture. I had to lower the trunk to make it look right.
