Recommended Suspension Enhancement to Reduce Porpoising on 2022 Ram 2500

Question

Question:

What is the best Sumo Springs or Timbren product for the following: 2022 Ram 2500, Longhorn, Cummins truck, 4x4 package with Bilstein shocks. Pulls a 31foot travel trailer in the 8,500 lb range loaded. We may upgrade to larger RV in near future that may be up to 2,000 lbs heavier. Note we picked the Ram over the Ford because my wife has back problems and the unloaded ride of the Ram was much better. Loaded, they are about the same but, with better payload in the Fords favor. Truck does not squat much or have any problems with current trailer except on the pavement in SD where they have cut slits across the road and the truck starts to porpoise up and down over that road. And, if we upgrade trailers I will top out the Rams rather low payload rating 2,165. Oh, I have an 40 gal axillary diesel tank in the Ram that eats up payload. So, purpose of the SS or Timbrens would be to lessen the porpoising and possibly give less squat if we upgrade RVs. Does the rebel fit on this truck with the coil spring rear of the Ram? Which product would not reduce unloaded ride quality. Which, if any, would reduce porpoiseing if I spelt it right? All the installation videos show trucks with leaf springs. Thanks

The best choice for your 2022 Ram 2500 are the SumoSprings. Both would help with porpoising front to back, but since you are concerned with ride quality the # SS64VR is going to keep the impact on ride quality at a minimum.

I've heard a lot about South Dakota interstates, and you definitely don't want something that is a chunk of rubber like the Timbren absorbing the shock. The SumoSprings Rebel # SS64VR will give you a much better experience. Also, they won't have any issues installing with the coil springs. The 2-piece design will allow for unlimited suspension travel and it sounds like 3,000 lbs will be enough for the capacity. If you think you need a higher capacity the # SS27GR will also fit and has a weight capacity of 5,000 lbs.

Another thing you want to do is make sure your trailer is loaded correctly. You want the weight to be properly distributed, with 10-15% of the loaded weight as the tongue weight. If you don't have enough tongue weight it can lead to porpoising.

If you don't already have one, you may want to consider a weight distribution hitch like the # EQ37100ET. This will help with sway and porpoising as well. You want to choose a system based on your loaded tongue weight. Ideally it will fall into the middle of the range of the WDH. This Equal-i-zer has a tongue weight range of 600-1,000 lbs.

I have attached a link below to all of our weight distribution hitches for you to check out, along with some review videos and helpful articles for your reference.

Because it replaces and installs in the same spot as the factory bump stop, the Timbren TDR2500D is compatible with your 2019 Ram 2500. The fact that your truck has the OEM air suspension won't affect the fit. The kit is compatible with both 2WD…

Answer 6

I checked with Timbren and they do not have any fit exclusions for their part #TDR2500D and your 2015 Ram 2500 with auto-leveling suspension so the kit will fit well and provide you with additional suspension support for the cargo you will be towing.…

I would choose the Rebel #SS64VR over the Solo #SSR-312-54 for your 2022 Ram 2500 for two reasons. The first is the capacity. Although there isn't much of a difference between the two, based on what you will be towing and hauling the additional…

Since the air bag suspension enhancement kits like the #AL57289 that you referenced would limit your suspension articulation since they attach at the top and bottom of the bracket you'd be better off with a kit like the Timbren part #TDR2500D…

Answer 10

The big difference between the Sumosprings Rebel #SS64VR and Solo #SSR-312-54 is the 2-piece design of the Rebel vs. the single spring of the Solo. In some applications the 2-piece design does allow more suspension travel since they can separate and…

For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle…
