Rear End Sag
There are many complains about at least the 2011-16 Super Dutys and having rear end sag when loaded. Has anyone seen (or not seen) the same with the 2017s? Did Ford address this? What's the maximum payload/hitch/pin weight you've had loaded?
Thanks

Mine sags almost exactly the same as my 2012 did. With about 2800# on the pin, I'm down almost an inch below level in the back. It's strictly an esthetic deal though as the suspension is performing as designed with the overloads not even engaged yet.

Bridge, I think your going from a 250 to a DRW has more to do with your decreased sag than the 2017 redesign vs. your 2014. That's a bit more of a jump. From what I've been reading and my experience, I think apples to apples, they sag about the same.

No doubt, totally agree. The OP didn't mention if he had a 250 or 350 preference, so I threw both out there. I'm surprised that the 2017 SRWs still sag as much as the previous gen, as it was always a topic of conversation in the 2011-2016 forum. Makes me glad I went with the DRW, which I wouldn't say "sags" with my setup...it's more of a leveling effect.

I've run Timberens to past vehicles and they weren't my cup of tea. They will impact the overloads on rough roads or bumps while driving unloaded and the slapping of the springs can make for a jarring ride. If I did anything to my 17, I'd go with Torklift StableLoad lowers. Nothing to leak or blow out like air bags and super simple to last the life of the truck. Plus they are either on or off. So, when disengaged, they have no effect at all on unloaded ride. Another member here has them for his truck camper. He said they brought him back up to level and eliminate about 1.5" of sag when loaded with a 3400# camper in the back. Not sure if I'm going with them or just leaving it as is. Def worth checking out if you're not familiar with the product though...

Hitched up to my Pinnacle last weekend; Jayco base spec of 2410# hitch weight before adding the 300# Onan generator, 12gal of gas for generator, and my gear. Measured 41" front and 44" rear from the garage floor to the opening of the wheel well with just the hitch in the box. Once the trailer was dropped on it the rear went to 41" and the overloads had only started to touch on the back side while there was still 1/2" gap on the front side; jounce bumper to axle stopper was 1-1.25" gap remaining. Very happy with those measurements since my 250 required air bags with 60# in them just to get the truck back to level. Still haven't taken the trailer out of the garage so I don't know how level it will be when standing back

I added SuperSpring to my 2017 F250 and it solved my issues when pulling my 5th Wheel. I had a fair amount of sag and the ride felt mushy, once the superspring was installed this all went away. The best thing about the superspring is they don't effect the ride at all when you don't carry a load.

I don't tow the weights most of you do since my Jeep and flat deck trailer are less than 8k, but I already can see my 2017 250 will not sag as much as my 2011 since the rear blocks are 1.5" taller. Even if it sags 1" when loaded, I'll be .5" higher than unloaded on my 2011.

Replaced them with Firestone air bags, which were flawless. Just my two cents. YMMV.

That would suck. I haven't notice any noise yet but will keep an "ear out" for it.
