Thanks Wconley

I am trying to correct a bit of porpoising that I get on concrete roads (I 10 especially!). The truck gets to oscillating and it forces me to slow way down. There does not seem to be any dampening and that really bothers me. I have a ProPride hitch and it has been set up properly with the help of sean. It works well. My stock shocks have 25,000 miles on them and I just wanted to try something else. My trailer really gets tossed when this happens.

The only 'shocks' that I found that helped 'road seam' oscillation were Edelbrock IAS...used them on our 95 3/4 Burb. But they did NOT eliminate it...in my experience nothing will, 'cept maybe a smooth road with no seams.😂
Out PPP hitch is great for no sway but does nothing for up/down.🤔
Summit...
"Edelbrock Performer IAS monotube shocks use a patented inertia-activated valve that instantly adjusts to driving conditions. It's simple enough: On smooth terrain, the valve closes to give you a firm ride, excellent cornering, and reduced body sway. Under rough conditions, the valve opens to make the shocks softer and more responsive. So, your wheels follow the contour of the driving surface for a smoother off-road ride. These shocks use polyurethane bushings for added responsiveness and their high-pressure, monotube design eliminates oil foaming and dissipates heat more effectively. Other features include nitro-steel piston rods, heavy-duty welds, and an attractive red powdercoated finish."

Well, I10, especially the Atchafalaya Viaduct is a challenge to us all. The expansion joints are perfectly spaced to induce a self-amplifying fugoid cycle or bounce. Many users of the Air Safe hitch swear it solves the problem.

I don't have one -- I just head north to I20 which is better but not great.

Had the same problem with my 2012 F350 6.7 Supercrew FX4.Switched shocks to Bilstein 5100’s at 10k miles and it changed for the good.Did the same thing with my 2015 F350 6.7 Supercrew FX4.I also run a AirSafe Hitch.

My truck is a 2017 F250 6.7 PS 4x4 Platinum CC Short bed - fully loaded with a Paragon bed cover. Everything is stock except for the shocks and Timbren springs.



The Timbren parts are on Amazon here (be prepared for sticker shock - they are not cheap based on what they look like but - they are very well made, have a great reputation, do what they claim, and are definitely worth the price IMO):



https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1



and here:



https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1



The front Timbrens are a bit tricky to install but can be done in the driveway - getting the nut to start on the bolt that holds the rubber cone onto the frame adapter takes some creativity and patience as it is inside the cone and the bolt is captive in the adapter base that you need to already have bolted to the frame before installing the cone. The back ones take about 10 minutes each - easy peasy.



The shocks I purchased were RANCHO RS999042 and RS999047A. Got them from RockAuto.com as they were the cheapest at the time. Google around for the best price and also see if RANCHO is running a rebate - they do it a lot. If they are running a rebate, be sure you purchase all of the shocks at the same time in the same order from the same vendor. I did not and it cut my rebate to less than half due to the terms and conditions of the rebate. These are adjustable shocks and I found they work best for non-towing set to 6. Towing, I set the rears to 8. They go to 9.



Many say RANCHO shocks are crap - mostly based on the fact the OEMs used by Ford are labeled "RANCHO". And yes, RANCHO does make them - but to the specifications of Ford - at a price that Ford is willing to pay. I had one rear OEM shock blow a seal in the first 6 months with minimal towing or hauling miles. The dealer said they would replace it free under warranty - with the same crap OEM shock - so I passed and upgraded myself. The RANCHO after-market shocks are built like tanks compared to the OEMs and many other brands I have used in the past. So far, I am pleased with my purchase decision.



I highly recommend going to both the Timbren.com and the GORANCHO.com web sites and using their product selectors to validate the part numbers above. My purchases were in October of 2017 and manufacturers are not beyond changing part numbers in nearly a year's time.



These changes made a huge difference in the ride and handling of the truck. The adjustable shocks provide a wide range of flexibility and allow you to tune in the ride you desire. It isn't like a sedan since it is after all a truck - but - it is much closer than with the OEM equipment!



Best of luck!

Again, if there is no problem with the shocks, why would you replace them?? Ride and handling of my 2017 F250 KR 6.7L 4x4 Off Road model is fine; no leaks and no "bottom out" signs...dealer confirmed....I just turned 50K miles. Maybe at 75-100K or if there is a problem...the OEM Ranchos on this model are fine.

I had a failure of one of the rear shocks in the first 6 months. And before that the ride was not good.

reducing cast iron and more turn on the adjustment jacks.. I have 1000 lb bars and adjust the bottom of jack tube some 6.5" up to have smooth ride. This is a 2003 7.3L F-250 SD pulling a 2005 classic 30 rear bed unit.

maybe you need heaver bars or more turns on jack screws.

The air bags were to improve ride and help level (yes, I know they do not increase payload).

It is difficult to understand why Bilstein has not developed shocks to fit the most popular truck in the world.

Better shock absorbers are always worth the price with a tow vehicle. Entry-Level BILSTEIN or KONI is “adequate”. One needs to move up a few steps from those or other suppliers bottom rung offerings. KING or FOX (and some others) also.

Body roll & body/suspension separation are the pickup vice. Where upgraded anti-roll bars (even just bushing material upgrade) are worthwhile.

Most of all, a rear Panhard Rod. (Get off your tail and find out how these act).

Since this crowd doesn’t set WD worth beans, it’s back to tire pressure as control. No more than what is necessary to carry the weight. But — like hitch rigging — I’d bet we’d find 90% have the wrong TV tire pressure.

Trying to counter bad truck handling/steering by tire overinflation. (Make things worse).
Put it on the scale for the Three Pass Method.

As to OEM shocks still working past 30k miles, yeah, sorta. The gas charge has leaked away, but if the hydraulic fluid isn’t leaking, they’ll be declared “good” (which they are t).

I just ordered 4 Bilstein shocks for my F-250 2017. The rear shocks are now available from Bilstein. I got mine at Summit racing for nothing off.

Front BSN-24-274937 $84
Rear BSN-24-274944 $104

I did look into the Fox 2.0 shock as they were available for the truck. They are much pricier at $165 / each.

I also ordered and received a Ford sway bar kit for my truck ($349.00) The platinum 250's did not come with one. The dealer actually went out to look at my truck and was scratching his head. He thought it had one standard.

I'll report back how they are. I won't be able to test the trailer until April.

I loved my Bilstein's that I had on my prev tow vehicle. Not sure of the Ford offering from them, but in GM land, there were 2 different models that would fit my application. One a bit more forgiving, the other a bit more stiff. I opted for the slightly more forgiving ones as they allowed me not to feel every pebble on the road, but still a vast difference from stock shocks....bottom line, you really can't go wrong with Bilstein.
