So I'm starting this outside of my build thread because I need help in a specific area. Here is the truck as delivered. It's on stock, probably worn out springs. It's riding on 33x12.50-15's with stiupid backspacing.
The rears had a busted leaf, so I replaced them with new springs for an 80-95 f250 that have the same approximate weight rating but with 1.5" more arch than the factory. I plan on running a 35x12.5-16 or 17" tire. What should I do to the front springs to bring them up? It's currently on jack stands with the box off, so I have no points of reference for measurements except a rear axle to frame. The front axle is out.
I was thinking super duty front springs, but not sure on how much lift they give. I'd love to have the front springs changed before the front axle goes back in, I want it to look right on the 35s, Help!
I'm gonna sub in on this. Not cause I have the answers but because I too am interested in more facts about this spring swap. Someone ( dont remember who now) had posted some links not long ago to a company that has parts to aid in keeping the geometry correct when swapping in superduty springs.
I already bought brand new rear leaf packs. Maybe let's make it easier: how much lift do I need to clear 35s, and average, how much lift do people actually get out of super duty front springs? I hear anywhere from none to 4".

This is the exact reason why I didn't go with Superduty front springs - I didn't want to do something twice lol.
For me personally, there wasn't enough info out there to justify doing the swap to SD springs... I replaced stock with stock and saw an increase in overall lift on the front end by 1-2 inches depending on which side we're talking about.
Stock superduty springs will get you about 2". Some of that is from the spring is self and some of that is because you have to build different shackels for the front springs and they have to be longer than the stock ones.
The skyjacker 4" springs will be plenty to clear 35's but they are build to mimic the stock springs with just more arch built into them. The superduty springs are a more advance spring design and should ride better than the stock springs or the skyjacker springs.
I have superduty front "leveling" springs on my 79 F350 extended cab. These are a 5 leaf design and I made rear shackles that are 1.5" longer than stock. This gave me 5" of lift and was actually more than I wanted. This made the front end higher than my rear with stock springs and a shackle flip kit installed. I have since taken out 2 leafs to get it to about 3" of lift. Turns out i should have gone with stock superduty front springs and not the leveling front springs.
The super duty springs do ride a lot better than the stock F350 springs did.

Do you have a thread we can read up on this? Did you have to do anything other than make new shackles? How is the axle placement? I thought I'd read the superduty springs moved the centerline forward or back.? Idr...
What's wrong with the wheel offset? Looks good to me.
When the front wheels are straight, the tires are at least 2" past the fenders. I'm not going to do this much work and paint it for the tires to just spray rocks and crap on the body.

I didn’t make any new brackets, I think all I had to do was drill out the holes and grind the bushings a bit to fit. These are 4-6” but it should be the same for any lift
also, they were cheap. Think I got them from jcwhitney or maybe rock auto for less than $300/pr
