Possibilities to lift a 1986 F350 Dually 2WD

I like to lift my 1986 F350 Dually 2WD about 4 inches.
But it is very difficult to find someone with experience here in Germany.
I would really appreciate some advice in this matter.
I like to have a professional solution. I also need information where to order the stuff I need for the lift.
Thanks a lot in advance!

What type of front suspension do you have? Is it the twin I beam and does it have coils or does it have leaf springs? You need to figure all this out when trying to get a lift for it.

Here is a place that sells some sort of kit and they say it's for 2wd f250-350. You still need to figure out what your truck has under the front.

Thank you,
I will find out the type of front suspension later the day and take some pictures.

That looks like a coil spring & twin beams with kingpins.

The thing is if you try and raise or lower that type of suspension more than a few inches you run into issues where the tire leans in or out at the top.
This will cause tire wear and bad handling.

In your case to raise the truck you have to drop the beam pivots and radis arms brackets to get the tires back where they need to be.

Thanks a lot for the information Dave!
How many inches are ok without dropping the beam pivots and radis arms brackets?
I desire 4 inches.

Regards,
Erik

2 inches is not enough. When I lift the truck I like to have 4 or 6 depending on the max. possible tire size on my wheel rims.

Does that mean that I have to buy new beam pivots and radis arms brackets, too? And where to buy?

You are looking at an axle swap to get those numbers. Otherwise combine the 2" suspension lift with a 3" body lift (taller body mounts) to get you 5" of total lift.

Not actually sure what other 2wd front suspensions there are besides the twin beam. Be a waste doing a solid axle when you don't have 4wd. Might be the only option.

Mean it makes no sense to lift my F350 with this front end?
Just a 3" body lift is not a problem? Any additions works needed for a 3" body lift?

Thanks

Call those people in the links I gave above. If they have a 4 inch lift kit, the kit will come with dropped radius arm brackets, dropped pivot arms, dropped pitman arm for the steering box, longer shocks, and extended length brake lines may be a option, or you can remount the brake line brackets. For your truck the kit will probably have taller coil springs.

I clicked on one of the links in my link above. https://www.rockymountainsusp.com/lift-kits/suspension/ford/2wd/f250-f350/1980-96/184f2k-sk.html?c=308&i=0

It gives you a list, dropped radius arm brackets, dropped pivot brackets, taller springs, spacers for the rear axle and longer u-bolts for the rear axle. They do say you will need to buy the dropped pitman arm separately and the longer shocks separately.

Yep. Any lift, body or suspension, will require some adjustment.

For a body lift, steering column angle will change, shifter will shorten itself if it's a manual, an automatic will need linkages tweaked for the extra distance from the stock body height being changed.
​​​​​​
Less things to do with a suspension lift. The 4" kit that was linked looks like a fit for what you want.

The main thing I do not like when you lift the body, the fan doesn't line up with the radiator anymore and you have to cut the fan shroud up. You could run a electric fan to get around this though.
