HD coil upgrade

[Bozo]

Could always add a front receiver and load some gear up there for ballast to put weight back on the front axle.

Thank you. I didn't realize how difficult it would be to get info specific to the question asked. I had hoped, given how knowledgeable readership in this HD forum is, they would have a fair understanding of all components of suspension, not just airbags.

So to answer your question succinctly, after following the advice of those much wiser than I, I selected a camper first, then bought a truck that could handle the weight. My load sticker is 3610, which is close to the max for a 2500, bought in May of last year, but due to covid, didn't get to see the unit I wanted to purchase until Jan. And was really disappointed and even though the weight was perfect, I passed on that purchase.

So not really knowing the exact weight of the camper I couldn't pass up, and half believing the dry weight sticker, I bought it. The bottom line is that I have a 4200 pound camper, wet weight, and my cat scale weights show im heavy 520 pounds on my rear axle.
I put timbrens on first and want to keep it that way, while failure of a bag or line in most applications requires a simple fix, it could be disastrous while overweight. I've seen enough airbag failures to know I dont want it, and the amount of pressure needed is not something I think is necessary.
In addition to being overweight, my front axle has lightened 300 pounds with the camper on.
So...I purchased vision 19.5 wheels which exceed the 3000 lb stock 17 inches I have, I also bought h rated tires which also have a 4000 pound rating. So I'm confident that my tires and wheels are rated higher than my load.

I also noticed the bump stop in the front of my camper is huge and will cut that to fit my truck, allowing my center of gravity to move forward almost two inches. I will also gain a physical height of an inch and a quarter from the bigger wheel, increasing my rake, which I hope will transfer some of the weight forward onto the front axle.
I'm not too concerned right now with sway, going up a driveway results in more side to side than I care for, but I realize I have a high center of gravity from several factors, all with the type of camper I have.

Which leaves me with coil springs. I'm not necessarily looking for more height, rather something thats not going to let go at the worst moment. Its been challenging to even find out what the weight rating is for stock springs, if they even exist or are measured as such. Most of what i can find in aftermarket weight ratings add up to less than the 6000 pound gawr. So is the rating for a fully compressed spring? Can someone explain how weight ratings are arrived at? Next is cost, supersprings are 600 bucks, while cargo Maxx and Daytons are a third. Why the price difference? Lastly, progressive or linear?

Transports run bags and rarely have failures.... i call ******** for you seeing bag failures unless they are garbage bags

don’t knock us for giving you solutions. You’re doing it wrong. We are trying to help. Well, we were. I’m out.

You bought the wrong truck or the wrong camper, or both. You should’ve researched and asked questions before you bought. Now you’re in trouble and we can’t help you.

You've given nothing. I've asked for information specific to coil springs, which you are unable to provide. Most people, when they don't know what they're talking about, typically remain silent. I've mentioned coil springs half a dozen times, it just doesn't seem to register with you. Sorry I can't help you, im not looking for an argument, im looking for information about coil springs, im actually amazed at how you can dance around my question without answering it in any useful way.

So you don't know the first thing about coil springs or you're just looking to argue about airbags? Holy smokes man!! Try some decaf!!!

Common signs include the rear feeling loose or spongy, a bouncy or rough ride, the air compressor running frequently, and sagging on one side.

that site is talking about oem bags not firestone aftermarket bags.... i know tons about coils i also know you looking for progressive rate or increased strength linear coils to haul a top heavy slide in camper is a terrible idea.... now if your so stuck on coils the super springs are the best.... now the 2 biggest reasons air bags are the best idea for your setup is stability and reducing the risk of bending the axle as the bags would be closer to the wheels removing a ton of leverage force that the bigger coils can cause....

Try a truck suspension shop!

There is a ton of knowledge and willingness to help on this forum. You asked about coils but you also added a bunch about your use case, and then got upset when several people said that's not the right solution for your use case. If you want specs or reviews, there is Amazon, eTrailer, your local truck shop, just to name a few. If you want to solve a problem go to a forum. If you want to find others to agree with a bad idea, go to Reddit.

This would be like me going on an electrician forum and stating I am adding a 50 amp outlet in my shop for welding, who makes the highest rated 14/2? Either the replies make me realize I am about to burn my house down, or I already know it will burn my house down and I don't include the background info in the original post to avoid the obvious warnings. Option C, tell the experts they are idiots and just tell me where to buy the wire at doesn't elicit the best responses.

Shoving 4,200 lbs into the bed of a 2500 is a really bad idea, you've admitted as much. Even the dry weight was too high when you factor occupants, etc. Anything you do short of making it a 3500 is going to be a lot of dollars for not a lot of gain. You've already gone taller which is making the problem worse. Sometimes we get into bad situations that cost a lot of money. Education is expensive, and it will be even more expensive throwing good money after bad. Plus, this is a safety issue for you and everyone you pass on the road. Responsible people generally don't want to facilitate that no matter how politely you ask.

But what do I know.
