SuperSprings SSR-307-40 | SumoSprings Rear for Dodge RAM 1500, Blue, 1000 lbs.

I got this for a 2020 Ram 1500 with a RC 6” lift.The passenger side was a bit tricky on the two back bolts. It sits about 2.5” above the sumo springs.It rides smooth and only rough if you hit a pot hole. When I hook to the utility or dump trailer, it holds it up without squat until loaded.I am happy with the ride. I didn’t use the spacer because I wanted room before bottoming out. With the spacer you only get an 1.5” then hit the bottom. The springs don’t give without any weight. Works great and easier than airbags.

They were simple enough to put on, but just by the arrangement of the suspension components and location of the bump stop mount it took about an hour start to finish. The bolts on the outside of the bracket, by the suspension springs, were the hardest to get to and only allowed about 1/4 to 1/8 of a turn at a time. I didnt use the included spacer, because I dont keep my truck loaded down all the time, and the springs just barely touched the axel pads. It had a little more rebound on the road compared to the factory setup, but not a bad ride at all and prob not noticable to anyone that didnt know these were installed. Very pleased with the springs.

So far so good. 4th gen Ram 1500 Ecodiesel 4x4, factory ride height. Regularly carry 1,100 pounds in the bed and the truck always squatted badly. This removes that completely.If you truck is the factory ride height don't use the spacer because you will be bouncing up and down on the spring and it will be 1.) loud and 2.) uncomfortable and 3.) probably will eventually damage either the spring itself or the pad on the axle tube (where the bump stop contacts on a Ram 1500).These are designed to NOT be constantly slammed into the the bump stop contact plate. They are designed for you to load weight, the spring contact the bump stop plate GENTLY AND STAY THERE, until you unload the weight. This isn't a hard concept but a bunch of the reviews don't seem to understand this. If you don't understand what a part does or how it works, don't buy it.

Installing them is a chore, the instruction are not good at all, I had to reinstall passenger side which is no easy chore. With the drivers side you will want to install the bolt in the plate toward the rear of the truck and toward the tire , the passenger side will need installed toward the rear of vehicle and toward the axle or the bump stop will Not sit centered on the plate. The hardware is zinc so don’t expect a long life if installed in the rust belt. I would suggest using a 1/2” ratchet wrench as you can’t get a 1/4”drive socket on the nuts because they welded the studs to the bottom plate for some reason so you have to install the nuts on top where there is very little room to turn the nuts, I had to reach through the fender well to get to a few. Unloaded ride was similar to stock, I picked up a load of firewood in my 6’ bed and No squat or difference in ride so I’m happy so far .

I was skeptic about these. But they did the job. They absorb every bump and bridge on the highway while towing a camper. I will also say that it did stiffen up the normal ride of my truck. But it’s nothing too crazy still noticeable. But not crazy

DO NOT buy this product if it gets to freezing temps. They turn into rocks upon freezing and your rose is horrible. No way these are rated for anything under below 30F. Excellent warm weather only.

These took a tiny bit longer to install than I expected because of the design of my suspension (driver side was easier than passenger side) but still very easy. Once installed, the trailer barely squatted the truck at all (maybe 1” used to be 4”) truck rides just as smooth as ever and without a trailer you wouldn’t know the difference.

Got these to reduce the drop on my truck when using my travel trailer, to date we have only used locally but plan on a big trip in the future. I'm hoping these used in conjunction with a weight distribution hitch will result in a more safe, stable and comfortable ride. As they say "Proof of the pudding" thus I'll up date this review later. Installation was very straight forward, I'm not to limber at my age but with the help of a jack and axle stands I was able to install them in about an hour. NOTE: I did find a ratchet ring wrench made the work much easier owing to limited access when tightening the top plates. After 6,450 miles over less than perfect roads and rough trails towing a 7,000lb travel trailer it's my belief this device improved the ride quality by damping out the more than normal vertical travel of the suspension as attested to by my wife who is very critical when it comes to pitching and rolling. So I'd have a they provided a marked improvement in ride quality.
