My 78' has a 7'5'' meyer's plow on the front of it, well this was it's first year for a plow and the coils didn't like holding it up, so the left side decided to let go. lol, anyhow... my dad's 78' camper special, has the quadrashocks up front w/ heavier dia. coils, someone told me these were the same as the broncos. Is this correct? I would like to make my suspension as stiff as his, mine really sagged w/ the plow on the front as appossed to his sagging very little. Now it's sags alot! hahah, Thanks all to those who reply. Any advice on something I should do differently would be nice, I'm kinda on a budget so I plan on junkyard shopping. Also, any tips on the removal/installation of the new springs would be very helpful.

 

Coil springs are very dangerous without the right tools. I woud not waste MY time with junkyard coils, You can by new coils for around a 100 bucks. use a coil spring compressor or you may also use a floor jack with the right knowledge

as far as being the same as another truck have the local auto parts store look up both of the trucks to see if they are a match

 

coil springs on these trucks are very easy to replace, just jack the truck up and take the wheels off, jack it up by the frame, then support the axle with a jack, take the 2 bolts out of the bottom cup, then take the 2 bolts out that hold the top of the springs on, remove the shocks, and lower the axle down. might have to take off the radius arm brakcets. Don't need a coil spring compressor, but a torch might help to loosen up the bolts. Watch out for rotted springs in the junkyard, I have found them rusted apart.

 

You are so correct hillbillyk, but for the first timer not knowing how to do it or with no experience I figured to go the safest route possible with advice.

That is why I stated with the right knowledge it is very easy with a floor jack

 

thanks for the replies guys, I appreciate it. but I think my real question was what should I replace them with? r bronco springs a good choice? if not what would be? stock? thanks again.

A heavier duty coil spring is available as a stock replacement.

It has a higher spring load rating.

 

Also in the back of the coil spring book they give a break down on the springs. MOOG I know does for sure, you can look up the OE spring and go in the back of the catalogue and compare it with the other springs. Look at the spring rating, length, coil diameter and load

 

hey guys,
I noticed you are talking about a coil book?
I have a 77 F250 and i rub the inside of my fender well everytime i take a bump (at the same time as a turn), i was thinking about a 2 inch front end lift? i am also looking to put a heavier duty bumper up front, that would increase the front end load, can anyone point me in the right direction to look for heavy duty or taller coils? I have searched the interent and no one seems to make them. thanks in advance.

 

jmn6: Your original springs are worn out. You can buy over the counter replacements for a say a 460 and get some increase in ride height that may bring you back to normal when you get the bumber on. (provided, of course, you don't have a 460 already.)

A little bit, about an inch or so, of "free" lift is available by shimming the bottom perch with some big washers.

gcfisher: I'm with everybody else. You may get lucky in a junkyard but new is the way to go. Whatever you get, new or used, the surfaces need to be free of rust pitting and/or nicks. Springs are one the most highly stressed parts, period. I bought some extra rate without changing ride height by dropping some springs scavenged of some MacPherson struts inside the stock F250 springs. This took a little imagination (like scavanging the perch off the strut and sticking in the ford) and a tape measure but got about an extra 150-200 lbs/in of rate. This might be a cheap fix for you.

There is a nifty thing "coil spring rate calculator", search for it on Google. It really works and will allow you to make accurate predictions of where a different spring will put you. GL
