As some of you know I own a spring shop and the one spring none of my suppliers has ever produced is the 65-72 F100 springs and I get some calls for them here and there but was just wondering the interest on the following springs. They'd be an exact OEM replacement, made in USA and would range between $150 - $170 per side. All input would be appreciated.

1965 - 1972 F100 2 wheel drive with standard shackle 5(4/1) leaf
1968 - 1972 F100 2 wheel drive with EZ Ride shackle 5(4/1) leaf
1968 - 1972 F100 4x4 6(5/1) leaf

 

I have a 71 F-100 4x4 and I've swaped mine out used for used Three times. Tried rearched with only poor results. Mine are nine and ten leaf spring packs. What does 5/1 leafs mean? My problem is axel wrap from the weak narrow 2 1/4 inch springs. The last used set I installed I added a Full lengthed add a leaf from a Highboy kit. I'm not ready to buy springs right now. Thought I'd give you some feed back though. RKD.

 

There where a couple different springs made for the 4x4. One was the 9 leaf and the other was the 5/1 and when I say /1 that means it's a 2 stage spring with the top 5 leaves arched together and then a thicker, flat bottom leaf called an overload so when you put weight on the rear the overload engages not allowing the other springs to bend past this point. They both sit the truck at the same height so that's another decision is to build the 9 leaf or the 5/1?

 

I'll be in touch with you in the near future about springs. The previous owner of my 68 F100 must have lived in the desert (lots of sand) and never, ever washed the underside of the truck The springs are worn to a literally razor thin edge on all the middle leafs at the ends.
So those have to be replaced, and I'd like to get some contact info from you if possible.
Thanks,
David

 

I just put a set of these on.
