Ok so just dropped 3k at my go to shop for brakes, front end work/alignment etc and one thing I asked them do was install the Rancho dual steering stabilizer kit and rancho single steering stabilizer(Goes above the dual kit)and yesterday on my drive home the steering/handling was much worse then when I brought it to them so I parked it till I could look at it today.
Well today I go check it out and they put in the dual kit and removed the upper stabilizer unit, BUT didn't put the new one in and left it empty as they say the instructions say to remove it, BUT every installation video I've seen shows the upper still there after the dual is installed same with all the pictures I see so should I be putting the new Rancho single unit up there or just leave it as is?
I mean the front end feel like total crap now so I'd imagine the single unit should still be up there working along WITH the lower dual unit no?
If I was using steering stabs as a band-aid to mask death wobble, instead of correcting the problem, I could see myself leaving the OEM single on. But, I would remove the single under all other situations.
I installed my dual kit, took about an hour or so. I have a 19' F350 xl edition CCLB SRW.
I removed my old unit and just went with the new one.
Drives better now
Never had the "death wobble"
Haul a 5k camper so everything's gotta be tight.
It is.

Yeah I don't have death wobble either, but front end still likes to wander if road isn't nice and flat and that's after redoing the whole front end even u joints and steering box so just trying to improve it best I can before I start towing my 8500ish lb bumper pull TT.
Mind you truck has a 6" lift so probably as good as it's going to get, but I'll try installing the dual unit with single still on and see if it handles any better or worse and go from there.
Tires were at 65psi on last test drive so I'll reduce to 50psi and see if that helps at all before doing anything else.
Somewhat similar story here too. I have a 4" lift on my rig.
Running Toyo 35x 12.5 x 18's on Method NV304 HD rims and have fox 2.0's all the way around.
When Im loaded up I inflate to 80psi and around town about 65 on the front and 62ish in the rear.
I crawl under my truck a couple times a year and make sure everything that needs to be tight is just that.
Good luck and have fun with the TT.

I have Rancho shocks all around and they look a bit old, but feel ok and this weekend I'll be playing around with the front end a bit more and to prevent the steering box nut from ever coming loose I'm going to give it a half second tack weld with some .20 flux core.
Curious why you'd run a bit less psi on the rear tires though?
Less air in the back because less weight.
I'm approx. 5k on the front axle and around 3k on the rear.
Front tires are carrying the diesel engine weight.
The rear just carry the aluminum bed
Simplified of course.
My truck is set up to haul my camper for the most part.
Stiff shocks, aftermarket progressive springs, sway bars front and back, 5k airlift bags.
When I drop my camper off at the campsite and use the truck to just drive around empty 80psi would kill me.
So I drop the air down and I also have a Viar compressor to air back up when I'm ready to load again.
Down in Baja off road or even around here for that matter I can air down to 35ish with camper when driving in sand to keep from getting stuck.
Air is your friend.
