i could have swore i readd on here somewhere about someeone putting f250 coil springs on an f150 to get a little bit of a lift? is this true? does it actaully work or was i misreading somewhere? ive beeen searching around and cant seem to find anything. im trying to get a small lift on mine like 2 inches so im probably going to go with the add a leaf in the rear and f250 springs up front if that works? if not i may just buy the fornt leveling kit.
anyone know anything about this? does it work? is it a simple swap or what?
i know the 2wd version of the f250 is coil over i know visually the springs are beefier, im not 100% on any height differences tho i know they are stiffer so maby not so much as a lift and more of it just not sagging as much. i have been looking to keep my truck 2wd and keep the ibeams, but i have been interested in the bronco dual shock towers for some time :P
Many guys on this particular forum, myself included, have traded in the F-150 front coils for F-250 2WD coils. The lift usually averages from 1½"-2" (I'm not much on lifts, but I AM big on towing stability!), and there are only two main issues that seem fairly common. One is that it's difficult to get the alignment within spec after the swap...even the most aggressive camber bushings will usually result in a slight positive camber. So far I've probably put about 4000 miles on my truck since the spring swap, and there's no abnormal tire wear...but 4000 miles might not be enough to notice a problem yet.
The other issue, while a bit more rare, is that some guys that have done the swap have reported the spring is too close (read: touching) to the lower ball joint nut. This seems to have more to do with the spring manufacturer than anything else, but (and hopefully someone will correct me if I'm wrong) IIRC the MOOG springs are more likely to cause the problem.
If you're looking for a relatively cheap lift in the rear, consider some F-250 rear springs. Check your yellow pages to see if you have a spring shop locally...I picked my 2800# springs up for $244 for the pair, which beat the pants off any prices I found online. I left the factory lift blocks out in order to reuse my original U-bolts (which some folks advise against...I suppose if money is no object, buy new ones). Or, since a 250 spring pack is considerably thicker than the half-ton, you can get some longer U-bolts and use your original lift blocks. My truck sits dead-level now with the 250/350 front coils and the 250 rears without the blocks.
Last thing to keep in mind is that whether you go add-a-leaf or 250 springs in the rear, the ride is going to get stiffer (the front springs didn't seem to make much difference). But the way I see it...it's a truck, and it's s'posta RIDE like a truck!
I have to say, having done this mod as well, that the results sound worse than they are in reality. The f350 coils make the truck feel stronger and steadier. I find the truck does far less bouncing and pitching. Count me as someone who did this swap and really like it. I live on an island where the roads are twisty and rough, with lots of potholes and bumps.
are these direct replacements without any modifications? will i need an alignment or anything? sounds like im only going to gain around an inch or so. so will the coil spring spacers work with it as well? if i do that will i need new shocks or extended brake lines or anything like that?
New shocks or brake lines - no. Alignment - yes. Coil spacers as well - maybe. When you install the f350 coils, you need to install adjustable camber bushings as well to permit proper alignment. I'm sure there are bushings that could also take spacers into account as well. I installed my springs myself - easy - and then took it to an alignment shop where they installed the bushings and adjusted it. I believe I gained 1 1/2" with mine. The springs that I took out were still in good shape and weren't sagging.
I put in the springs myself also, Its very straight forward. You dont have to change the shocks, but I would recommend it if theyre old, it will make it feel even better. And you do need to get it aligned after install.
You can lift about 4" without needing extended brake lines. After that, your going to need them.
And I wouldnt recommend the coil spring spacers, if theyre the ones im thinking of, the ones that twist in between the coils, those can be dangerous, and they just look crappy IMO. Thats one of the main reasons that I went with the F-250/350 springs in the first place, to get rid of those things.
