2027 Ford F350 Tremor Suspension Upgrade

[Whaler27]

Hi Everyone, I'm new to this forum and am seeking some advice.

I just took delivery on my new 2027 Ford F350 XLT Tremer. I went XLT so I could get the baja cloth interior which I think is killer.

Here's my problem. I have a ranch in Mackay Idaho that is accessed over a single track mountain road that is nasty and I mean nasty. Heavy washboard, ruts, pot holes and sometimes rocks roll off the mountain side. I took my new F350 Tremor over that pass yesterday and I'm surprised I have any teeth left. It was so bad, I can't even describe it accurately.

So, I need to change out the suspension and I'm wondering if there is a 4X4 company that specializes in upgrading Ford Super Duty suspensions. I'm lucky that I ended up in a good economic state so I can do whatever it takes to get this thing to ride like a Raptor, hahaha.

Any thoughts? Thank you.

Dealers often have the tires set at their max pressure, which guarantees a terrible ride. If you’re not carrying super heavy weight, drop the air pressure this morning. I went from max pressure Duratracs to moderate pressure 37” AT3s and it transformed the drive from truly awful to okay. Carli would do much more, of course. I still miss my Raptor’s drive, which will never be duplicated on an 8500 pound diesel F350, but I needed a real truck to do real truck stuff.

Kind of becomes a double edged sword if you’re hauling fairly heavy you can’t have both heavy haul capabilities and super plush ride (to an extent) there’s going to be some trade offs best bet would be call Carli and have an honest discussion with them and they can get you a plan that works for you, keep in mind it’s going to get real expensive real fast lol

I vote we only keep giving advice to @F350IdahoTremor if he allows a meetup at his ranch!

Only half kidding… Unless they’re on a fork of the Lost, then I’m not kidding.

Definitely play around with tire pressure as others have said. Dropping to 25 or 30 psi all around makes a huge difference. Ditching the stock shocks for Bilstein 5100s also made a difference. Airing back up for the highway is a snap with a good compressor.

Most Important: The Big Lost below the reservoir is amazing. Everyone talks about Silver Creek, which is ok I guess (highly technical and lots of pressure/fishermen). I've fished it all and the big lost below the dam is arguably Idaho's best fishery Below is a quick video of my wife fishing with our two goldens

Next Important: The idea of airing up and airing down constantly isn't very appealing. Often times I return across the mountains late at night and I'm beat from working at the ranch, so the thought of getting out and airing down the tires and then airing them up again on each pavement side, is not something I want to do. I'm thinking a full suspension upgrade is the way to go. If that doesn't work, then I guess I'll have to buy one of those THEME Y Raptors (I guess I can remove the decals

I don't really have a need for hauling. I like the size and the look of the Super Duty. I'll try the Carli suspension first and if that doesn't do it, then I guess I'll have to buy a Raptor

 

[F350IdahoTremor]

Valid point. You cannot get a super duty to ride that well, not even with any carli kit and tire/rim combo. A HD truck with a solid axle serves a purpose, it’s simply not going to ride that well.

If a Raptor ride is a 10, what score would you give my F350 Tremor with a full Carli suspension upgrade (I mean the works all the way front and rear)?

 

[F350IdahoTremor]

Like others have said, Carli seems to have the market for best suspension for the Super Duty truck... If money is available.

I just added the Fox 2.5 HTO's and run 40 psi offroad with dirt bikes in the bed of the truck. It works good for a 1 ton solid axle. I'll be added the 37" tires soon like everyone suggests to help with the ride around North Idaho too.

Lots of options for you. 37" at low psi, good 2.5 suspension and some weight in the bed seems to be the trick.

Great info SantaCruz, have you ever driven a Raptor across the roads you are referring to? If you have, what score would you give each (on a scale of 1 to 10) The Raptor vs. your modified set up?

The problem with dropping the pressure that much is then when I hit the pavement (for the rest of the way on either side) I fear it will be unsafe?

25 will be too low for driving a highway speeds, but you can drop it down proportional to the actual axle weights. Weigh your truck in the load configuration that you drive with on a CAT scale or other scale that gives you individual axle weights. Then take the axle weight divided by 8160 times 80 to get the minimum pressure for that axle. This is because our stock Tremor tires are rated at 4080 lbs at 80psi.

For example, my empty stock diesel Platinum Tremor with a factory winch and two people in the front seat weights 5100 on the front axle and 3500 on the rear.
5100 / 8160 x 80 = 50psi for the front tires and 3500 / 8160 x 80 = 34 psi rear. Those should be safe pressures for highway driving at speed limit speeds.

Outstanding info Sherman, thanks!
