Any info would greatly be appreciated. Have an 89 F150 with 4x4 TTB and wondering if it would be possible to put similar year F250 front springs under the F150. The reason for my wanting to do so, is I'm looking to install a 6BT cummins or 7.3l turbo diesel in. I would look at putting in a 4BT, but those engines fetch super-premium prices . Will they fit or will I be required to put an D44/50-HD setup under it? Or would I just be able to swap (cut/weld/unbolt/etc) out the spring seats?

 

F250 2WD springs will fit

 

Well, thanks! One more question, are they the same length as well? And thanks for the info!

 

Here is where I got my information from FullSizeBronco.com - 78 - 96 Ford Bronco offroad club, forums, tech, installs

 

Chances are, the stiffer set of springs will come from the F250
and they will be shorter to begin with but will compress less. :)

The shorter spring pictured there is the stiffer spring.
The dealership installed it for me under warranty in '75. :)

You can see the difference in the wire size there. :)
The longer spring came from an F250 I got an I-beam from.
Ford always did use wimpy-*** springs. ;)

i ordered f250 springs for my truck, same year, same drive (2x4/ 4x4). they were a good inch bigger over stock f150 springs, (maybe just junk after 160K).I liked them and they have worked out great still.. good luck!

 

Yeah, I definitely see the size difference! I'd definitely have to go with those longer springs. Last thing I'd want is the differential putting a hole in the oil pan... Or just sitting on the axle . Thanks for all the info and the links!

 

LOL :)
You see-it but you don't get-it. ;)

When/if we are talking Ford-made springs for a particular generation+series...
The shorter springs give a higher "ride height" than the shorter springs!
Believe it? :)

The spring with the purple and white stripes is ~.725" wire. :)

What me and Ford mean by "ride height"...
http://www.panix.com/~alvinj/file12/rideheight.jpg
The spring pictured there is ~.745" wire and was a shorter spring than the
.725" spring but gave a higher ride height because it's harder to push down.

That's why the wimpy spring is so tall... It's friggin wimpy and mashes down
easy. Too dangged easy! And "boings-up" (technical term) easy too. :) And
shocks can't fix wimpy-*** springs, BTDT in '75, BTW. ;)

If you are talking about after market springs, all bets are off. ;)

I got ya now. I figured the extra length in the smaller dia. spring would keep it from mashing down so much... Guess I was wrong. Thanks for clearing that one up Alvin.

 

Yeee Haaaw! :)

Wimpy springs give a soft mushy ride, right up until the suspension tops-out
or bottoms-out. Handling is crappy feeling too. Fancy shocks can't fix it.

Stiff springs are harsh feeling -if- they don't have high-quality shocks backing
them up or paired-up good shocks. Don't judge your new shocks until they
are broken in and that takes a fews days for regular shocks or maybe a couple
months for high quality shocks.

Everybody that rides in my "Ol Clunker" is amazed by how nice and firm the
ride is without all the bouncing around etc. Back when it was brand spankin'
new, it rode terrible, and I ain't kiddin'. :/

Bottoming out going across town in Willcox AZ on paved roads. The water is
funneled down the sides of the road and so cuts across the crossroad twice
on either side of the intersection. See what I mean? Those little ditches
required ~5 mph to keep the brand-new-Ford-piece-of-crap from bottoming
out! :/

I was pissed. :)

The Old Clunker rides like a top-quality pickup truck now! ;)

Anyway, that's been my experience.
