need a front spring

[rokhound]

working on the front end of the 47 willys i am using a 47 ford front axle i would like the spring to be on top of the axle and if you do the speed way math i need a leaf spring some where around a 36 long spring any one have some input where i can get one with out having one specially made[S

or any other options i have thought about running the spring like dons rods does his but i was just thinking it would be easier just have it hung on top less fab work

any help would be great thanks

That is the downside of using something like a 47 axle. They were designed to have the spring in front originally and when you try to run one on top of the axle it is tough to find a spring the right width.

Someone on here posted that they are now making a spring (possibly Posies) that addresses this width issue, but I tried to find it on their website a while back and couldn't. You might call Posies and ask, maybe it is something new and just not listed yet. The perch holes are 40 5/8 apart, and when you put early perches in those holes it moves the shackle hole inboard about an inch, I think, so you would need a spring that is about 34, if my recollection is correct.

i called them and they have a 35.5 and thats all good but they want 240 bucks for the darn thing yeah well i think i am going to try to figure out some thing else??

can i take my spindles and brake set up off this axle (speedway disc brake kit) and put it on a different one??[S

and if so what year of axle should i look for??

I have a disk brake kit on a 32 heavy axle. i think it's the same kit. look it up in speedway catalog and see if it interchanges. The thing is speedway doesn't sell a spring for a stock axle. I got mine from Posies.

 

[donsrods]

The axle that is easiest to find a cheaper spring for is a 28-36 axle. They usually go for about $100 at swap meets and on Ebay. I bought a brand new, unused 34 axle for my rpu project for $100 off of Ebay.

Then you go to someone like Speedway, buy the proper perches to mount the spring and wishbone to that axle, and a 31 inch spring, and you are home free.

Yes, Speedway does sell a lot of springs for the spring over setup. Look at the ones listed under "Superglide leaf springs" in their catalog or on line. They start at about $65.00.

Thanks for the feed back guys so don do you think my spindles and stuff will work on the 28 to 32 axle then???

 

[donsrods]

Sure, if they are Ford spindles, 37-48, they will go right on any axle from 28-48.

In the past I've gone to a trailer supply store near my place[20 miles]. They have about every spring you could want. quit a stock of shackles and bushings too. Just a thought on an inexpesive source.​

 

[rokhound]

the trailer springs that i have seen are way short and stiff. I am thinking about cutting a spring in half kinda like a quarter ecliptic but instead of running forward it would run out to the side??

what do you guys think??

 

[klink]

Is the '47 axle you already have nice? Is it the correct width for your project? I know $240 seems like a lot for a spring especially when "standard" springs go for so much less, but by the time you switch to a different axle you may end up close to that amount. You should give Detroit Eaton Springs a call, as already suggested. I've used them twice and they will build a spring for you for a very reasonable price...and they are fast.

 

[rokhound]

Kool I will look into them there is a place close in Des Moines called Huskey springs they build leafs also

 

[rokhound]

hey guys going to take this back to the top i have a question about shackle lengths:
-is there a certain length the should be

- what would you consider to long I am not taking 12" long but looking toward 6 to 7 inches long

the reason for these question is awhile back i bought a front leaf spring awhile back when i was going to try to use the front 4x4 axle anyway the leaf spring is 30" long so i was just going to make the shackles longer and use it.

what do guys think??

front spring 47 ford axel

I know this is an old tread but here is my two cents .I use a 48 F1 front spring, take speedway shackles and make them 2 inches cent to center used the speedway bushings that come with the shackles and ream the spring bushing to fit.

 

[rokhound]

thanks man thats what i needed right there i am going to try and use my 47 cj spring just like you mentioned

thanks man [cl
