SuperSprings

[Jack90]

Hi everyone,

I have a 2021, Ram 3500, diesel, single wheel, leaf springs, stock suspension, with a 3,000 wet weight slide in truck camper.

I do have aftermarket firestone air bags installed along with a aftermarket sway bar.

I am nit picking a bit, but I find the firestone air bags a bit bouncy, so I hit a bump and and the back bounces, then that make the fronts bounce and gets in a porpoising motion for a few seconds. I could go and get a pair of custom leaf packs made, but was wondering if any of you have the SuperSprings additional leaf installed and...

1. Do you like them?

2. What size do you recommend? I called and they recommended the SSA15 a load level capacity of 3,000 lb, but wasn't convinced of the answer. I wonder though if the SSA23 with a 2,300 lb capacity would be a better dampening ride?

I see air bags as more of a quick fix band-aid for what in actuality ends up requiring a more robust spring pack - naysayers aside, looking at the rear spring pack on our 5500 chassis cab RAM makes me realize there ain’t no such thing as a free lunch…

The best thing to do if you use the truck for the camper most of the time is to get a spring added if there is a good spring shop around.

I had airbags in an older truck, and I would never do them again. They take your springs out of the equation too much, causing the soft feel you described. If you run without the camper more than with then I would look at Stableload systems, which the lowers can be disengaged for empty driving.

I'm having the opposite issue right now the camper I got is only 2400lbs so my overload spring is almost engaged but not quite haha there is a weird ride

I tried super springs what a mistake. The best was going to a suspension shop they looked at the truck with camper on it and added a leaf with the right tension to level the truck

^ Yup, definitely nit picking. And considering your truck will handle 3klbs pretty well without any additional load support (but maybe a bit below level for sag), you shouldn’t need a lot of help from additional springs.
For cheap/free, you could try wedging the lower overloads tight (like lower stable loads). That will give you a higher initial spring rate.

The 3,000 lb came from weighing at the scales, so all good for being under payload.

For the shocks, I have some really great 3.0 king reservoir that have been tuned for the weight.

If you've played with the PSI on the bags, I would expect it to be an issue with the shocks.

Springs (of any type) will generally allow repeated bouncing without some other force to stop them. That's where shocks come in. They tend to dampen the repeating aspect.

Being a 2021, the shocks should be OK but probably should check.

One question: Where did you get the 3000lb from? Was this at a scale or off the sticker on the side of the camper. If it's the empty weight, you could easily be north of 4000-4500lb of load...so are you over the payload of the truck?

154? :E

Supplementing spring rate with steel will be more stable than with air.
However if your camper really only weighs 3000lbs, you are kinda nit picking, especially if your biggest gripe is a little porpoising and not body roll.
That said I’d take more springs over airbags. Until I had to drive around bobtail with no weight in the back.

I had an absolutely horrible experience with airbags. The dealer set them up about 45 psi. The bouncing was so bad I did not make it out of the parking lot. We dropped the pressure to about 15-20 psi. The ride was still bad so I got Rancho shocks and set them at maximum. There was still some bounce. Unfortunately the shocks gave a stiff, jarring ride.

Later on I got SuperSprings and the ride was greatly, greatly improved especially since I was able to back off on the settings for the shocks. I believe they are somewhat adjustable but that is a trial and error process that involves jacking up the rear end.

On my current truck, I have been able to get by without adding SSs. Instead I went to Timbrens. Way, way better than airbags. They help minimize rear end sag and increase the strength of the rear suspension without the bounce and sway. Even better when the camper is not on the truck they are not engaged and do not affect the ride.

We had then on our E350 22 foot b plus Motorhome. It both raised the rear end 2 inches and stiffened it up. They worked well for the 7 years we had the Motorhome.

You are probably running too much air in the air bags. You probably should be running 20-40 lbs. Also, you can extend the bump stops (if Rams have them) to make contact with the springs sooner.

Call Henderson line up for the best information.

I installed lower and upper torklifts on my F-350 and was able to adjust the lowers.
Are the SuperSprings adjustable?

>>They only say for the adjustability of - The SuperSpring includes a patented roller shackle on each end that allows for self-adjustment as weight is changed. This is particularly helpful as you add water, tools or heavy gear to your vehicle.
