I read somewhere people were putting early spring packs on late trucks (or maybe it was late spring packs on early trucks) so I thought that you could look into that. I think Ford actually has about a dozen different springs for different option packages and truck weights. On the other hand, going with an air spring or an over-load spring would retain the smoother ride the newer trucks are supposed to have unloaded.
Torque Lift Stable Loads - yep, they work, but IMO put undue bending stress on a single point on the rear springs, plus overworking the overloads instead of spreading the spring load
I’ve seen this concern arise on a few occasions. Torklift has extensive testing that has been performed both in computer-aided simulations in SolidWorks and physical testing on the factory springs. That coupled with thousands of happy StableLoad users in the field and never a single event of overload or spring issues ever having occurred.
To be certain our confidence in the StableLoad is being presented at the highest level, we also offer a lifetime guarantee not only to cover the StableLoad product itself, but also cover the factory leafsprings and the overload. We don't know a better way to instill confidence in our products than to offer this exclusive lifetime guarantee on both the Stableload and the springs.
It may be surprising to some that the overloads are actually factory engineered and designed to handle what we commonly put our trucks through in terms of towing or hauling larger payloads. The lower quick-disconnect StableLoads are effective in providing support in the gap between the lower overload and springpack without adding additional stress. It essentially pre-activates the factory suspension to reduce sway, prevent sag, and provide much better ride quality.
Airbags and StableLoads work great in conjunction – however in many cases I’ve seen, those who have tried the StableLoads first did not need to move forward with installing airbags. Take a look at this thread here: LINK
Thanks for all of your guys help with this situation. The airbags arrived today and they have a 60 day money back guarantee so I think I am going to give them a try. The set that I got replaces the jounce bumper but has jounce bumpers inside the airbags. This allows me to run them with no air for a stock ride and add air when I have a load. I'll let you know how it goes.
My 2013 F250 6.2 4x4 CCSB shows 2804 lbs on its loading info sticker - it's surprising how much the numbers vary with the different configurations.
I installed the Airlift Ultimate air springs (internal jounce) on mine. I became intimately familiar with every square inch of the underside of the truck and it took a while to get all the air lines & connections installed (but, I also installed an onboard compressor so, that added complexity).
Any way, the ability to vary the support has been really useful when towing our heavy travel trailer. I haven't had any problems while towing; the F250 handles it well.
