I'd like to raise the front of my truck to get it close to level. It is an 89 f250 4x4. There is About 3-1/4" difference from top of tires to body.
The truck has leaf springs in front.
Do they make a block kit that fits my truck? I haven't been able to find one.

And how high of a block can you add before it looks like to much body lift?

I'm guessing I'd want a 2 or 3" block in front? Do I want to keep it slightly lower in front?
Thanks

 

You NEVER want to block the front end. The cheapest way to do it would probably be to buy a reverse shackle kit. Being as old as it is and I'm guessing they are factory springs they are probably tired so if you were to replace the front springs that would probably bring your front end up a bit. But leaf springs aren't cheap.

 

I agree with the above...replace with new springs and stock ride height will be brought back. Never block the front end.

 

250 springs are negative arch from the factory.

Brad would know better, but I'd think a regular 350 spring would put you where you want.
​​​​​​​The question then becomes whether you can get the alignment back in spec with that much lift and a TTB axle.

 

Ok thanks. Springs are in good shape that are on it now. Just wish I could raise front. It's an hd model maybe that's why rear is so much higher? It appears to have a stock helper spring.
I'm guessing front f350 leaf springs would ride like a brick? If that option is rough, I like the reverse shackle idea. Or it's a new 4" lift kit which is over 1,000?

I like the idea of reverse shackle as it's affordable and my rear looks good, sits plemty high. but I can't find the right kit, I'll call a shop.

So if you go with say. a new 4" lift all around, will it sit level? I don't want it much higher in rear because I tow a boat and trailer. Will the 4" just bring it over tad over stock height in rear?the 33" tire fitin rear with plenty of clearance. A 35 would fit no problem and actually look better.
Thanks

 

A 4" lift is a 4" lift all around. The truck is going to end up with the same rake it has now...
*But* you can't lift a 250 TTB front end like that without dropped pivot brackets because you will never get it to drive straight.

350 springs are a *softer ride* than the inverted arch 250 springs because the TTB front end cannot deal with that much motion.

The ideal solution would be a solid axle swap from a 350, and leave the 250 rear alone.
*That* would get you level, get you a more compliant front end and a tighter turning radius.
But then you need everything below the steering box from a donor vehicle, and that's $$$
(pitman arm, all the steering linkage, springs, track bar, and an axle with the right ratio)

The only real difference between a 250 and 350 rear is the height of the lift block (2 vs 4")

 

Sorry, double post.

 

Look for the RSK reverse shackle kit. You can get it in different lift heights which is what you want. I believe the options are 2.5, 3.5 and 4.5 inch lifts. Also to improve your ride look into finding some U code front leaf springs from a 99-04 super duty I believe. Lots of good things are said about that combo.

 

Thanks for the options guys. Mxer of my fronts are about 3-3.5" lower now would I just go with the same lift size @ 3.5 or does it vary since mine is raked so much?

Is the kit bolt on for the most part?

I need new shocks regardless. Probably a dumb question, but will I need shocks longer than stock when I do the reverse shackle kit?

 

If your front is sitting 3-3.5 inches lower now I would probably go with the 2.25 inch RSK then get the 99-04 SD u or v code springs. That should put you at about level. At least to a point where it wouldn't really be noticeable. The kit is for the most part bolt on but I think you'll have to drill one bolt hole in your frame. Also from the other threads I've read on it I think you will need to find a shock that's 21-22 inches long. Also you should be able to keep your stock break lines unless you bump your lift to a 3.5 inch RSK lift. Here is a good write up on how it's done and you should be able to find the right shock length.

mxer, the *very first* paragraph of your link says the PMF RSK requires F-250's are converted to a Dana 60 solid axle. (This also means a track bar mount, SD springs and drop pitman arm *for an F250*
You would also need to box in the frame on a bricknose truck to use this kit.
​​​​​​​
Believe what you want... but you got the *right* information here, *before* you have the front of your truck torn apart and no way to make it work.

eta: Or Brad's thread here, https://www.ford-trucks.com/forums/1...l-fab-rsk.html

 

Sky Manufacturing has a RSK for the pre-'92 frames now. Minor welding required and looks like a decent kit.
Brad doesn't like Sky's stuff. He'll tell you shortly. I have used it and found no problems.

 

I addressed the link in post 10, not the sky kit.
Regardless, it's not going to work with a TTB front end (without drop pitman and pivots), so a SAS is going to be the first step like I said in posts 4 & 6.

 

I was giving another option.
Drop brackets are less expensive than a Dana 60. You're talking to a guy that wants blocks in the front he's not going to drop the $1500 (or more) on a RSK, Dana 60 and other associated parts.

Drop brackets, RSK, front alignment and done.
From Sky's site:
What it fits:
1985 to 1991 Ford F-350 4x4- Will fit F-250 4x4 with TTB drop brackets from Tough Country, part # 20852


Just priced the brackets. They are $168 from Summit. The RSK is $299.

 

Thanks guys. Yes I like the option better with the drop brackets to save money, and not have to rip everything apart. My kids take to much of my time these days. Truck is used on weekends, yard work, boat launching, and soon trailer.
I definitely want it done right, would rather leave it stick than do something that affects steering alignment etc.

Truck is clean, I haven't had the truck that long so I am not even sure the condition of the front end anyways. 4wd works great but I have a lot of vibration going down the road really bad at 35 to 40 then after that speed fluctuates. I'm taking it to mechanic to figure out what U joint it is or if that's all it is. So that will be another post soon.

So to clarify 99-04 super duty springs will be the replacement? What happens if you leave the stock springs? Just a worse ride? Height diff? Or would it just be dumb to do the conversion and leave stock springs?

Thanks for the help and links guys.
