+1 for the StableLoads.

My 2004 F250 Had Timbrens. Good, but not adjustable and barely adequate.

On my 2015 I added AirLift 5000 Ultimate airbags AND StableLoads.

I think the StableLoads made the biggest/best bang for the buck difference in towing my 13K# 5th wheel (both trucks towed this 5th wheel).

If I had to choose only ONE suspension add-on - between air bags, Timbrens, and StableLoads..... I'd choose StableLoads.

And a good set of shocks. I'm running Rancho RS9000XLs now and I'm happy with them.

 

I'd also look into TSB 13-03-08 regarding rear sag. It details swapping out the stock F250 2" blocks with OEM 4" F350 style blocks.

I plan to do this swap eventually.

 

Is this 1k weighed or assumed? That can make a huge difference. My trailer weighs in at about 6k loaded. I only drop about an inch before I put my WDH bars on and I'm almost back to unladen when they are on. I set it up on a scale though, I'm running about 816lbs of tongue weight or 13.6% of my total. I keep a majority of my gear either in the trailer over the tandems or in the truck bed up by the cab.

 

Another happy StableLoad customer here. I installed mine without removing wheels or jacking up my truck. Engaging them is easy without getting under the truck.

 

I was going to do this until I added up the cost of parts. IIRC everything came in around $2000.00.
Air bags were less than $400.00 and adjustable.

 

I did the 4 inch block swap on my dually. I wish I didnt because I have horrible axle wrap. I tried shimming the carrier bearing but that just caused the drive shaft in front of the carrier bearing that goes to the transfer case to be at an angle that causes vibration worse than the axle wrap. If I was keeping this truck, I would go back to the 2 inch block and then add air bags.

 

I have been debating between air bags or Stable Loads & I am seriously considering going with the Stable Loads on my 2016 F250 4x4. It sags more than I had hoped with my 5th wheel hooked up, although it does not bottom out or ride rough when towing it. It actually tows it very good.

Are you guys using the lower wedges (A7310), the upper spacers (A7200), or both?

Trying to gather constructive information.

Thanks

 

FWIW I used a WDH on my 7000lb TT and now have Timbrens for my fifth wheel.
Both worked well and kept the truck level.

 

Just the lower wedge kit. My 2015 truck doesn't even have the upper overload leaf that comes with the camper package.

 

Thanks for answering

 

On my 2000, I made spacers that gave me about 1/4 inch to the overload springs on just the rear end of the springs, basically a solid timbres. Had the material so it was free. Did not want to spend the money for the timbres for a truck I would be selling in a year or so. Ride was slightly rougher, but no squat. Had more squat than I liked even with the WDH before I made the spacers. I'd vote for the timbres.

 

I went with airbags on mine. Very happy with them. Nice thing about airbags is you can adjust the leveling depending on the amount of load and squat you are dealing with. And if you're not carrying any load, you can air them down and it just rides on the normal stock suspension.

Here is our 5th wheel with 2500 on the pin, stock suspension:



Here is same load, same pin weight, with Firestone airbags and 40 psi in the bags:

 

They made a world of difference didn't they.

How do they feel when traveling on bumpy roads or bridge joints. Does it have spring or like a shock sort of absorbs it and barely noticeable?

 

I have a similar setup, and I can tell you that while it's smooth, there is a significant amount of porpoising after going over a dip or bridge. It's too soft. I'm also running bilstein 5100's with my airbags.

I also have a 6.2 with the softest VVFF code suspension that came on an F-250 which I'm sure is contributing to the problem.

 

Yep, That's about what mine looks like with my camper hooked up in your before pic. The specs on mine say it has about 2500 on the hitch & total dry weight is less than 13k. Tows real nice but just sets my truck down more than I would like. Part of the problem is that mine is a Crew Cab SB 4X4 and it sets level from the factory, there is no built in rake to allow the rear to drop with the load. I have found it only has 2 inch blocks on the rear axle so I was considering swapping to 4 inch blocks (so the upper overloads will touch when the truck is setting level) and adding air bags. At least that is my current plan of action.
