Hey guys I am needing to know how many Leaves are in each spring, front and rear on a stock 1964 f100. Thanks in advance

Also how difficult is it to remove the spring packs?

 

C1TT-5310-C .. 6 Leaf Spring Pack - 1100 lbs. load rate / Obsolete

1961/64 F100/250 2WD / F250 2WD's were also available w/a 7 leaf front spring pack.

C5TZ-5560-A (replaced B7C-5560-A) .. 5 Leaf Rear Spring Pack - 950 lbs. load rate / Obsolete

C5TZ-5560-N (replaced B7C-5560-B) .. 6 Leaf Rear Spring Pack - 1250 lbs. load rate / Obsolete

1957/67 F100 2WD

 

I was kind of curious about this too. Regarding the difference between the springs on a 65 F100 4x4 with 5600 GVW and a 66 F250 4x4 with 6800 GVW. I have both and it looks to me like the spring packs are the same but I'm sure they shouldn't be. They both look original with D60 on the 66 and D44 / 9" on the 65.

Mine has 7 in the front, what was the reasoning behind this? Thanks ND

 

No, I'm not ND --- but I would say the reason was because the 7-leaf spring package that was originally ordered from FoMoCo.... whether it was the original buyer/owner ordering and buying what they wanted or simply a dealer ordering a truck that he figured he could sell off his lot once the ordered truck was delivered to him. -- BarnieTrk

 

I have removed mine twice already, it is pretty simple but you need heavy duty jack stands that go up 24"s or so with a standard 1.5 ton or greater. I used a 11/16, 13/16 and a 7/8's open ended wrench. Depending on what U bolts you are using, I went with 9/16's but 1/2 inch you might need a different socket. I even plan on doing it again once I have some money saved up for the mono leafs to lower it and get a better ride quality. I did the leaf flip to lower it about three inches around from the HAMB but the ride isn't what it used to be. Either way it isn't bad, the ride height it perfect for what I wanted. Good luck in whatever you are trying to do.

What are you trying to achieve by removing the leafs?

 

I'm actually planning on doing the leaf flip from the HAMB, can you give me any more information on how rides now compared to before? Any obstacles you had to overcome in order to make it happen?

 

The ride is ok, the 1st, issue in my opinion is you now have two reversed arched leafs fighting each other for flex. That makes it a harsh ride, I don't mind that so much. The 2nd issue is the steering wheel is off which is an easy fix as to just loosen the bolt on the pitman arm and straighten the wheel and reattach. If I were to do it again, which I might depending on my money situation; I would do the next shorter one vs the one the HAMB says to do. My stepside sits so even that my 3rd issue is with anything in the bed or just being parked on a hill the rear looks lower than the front. 4th and not really an issue but you have to work around it, on my rear leafs of my stepside I was not able to get the bolt out of the front eyelet. The fenders are in the way completely. It is doable still on the truck, I used a three foot long threaded section to run down a nut then used a big C clamp to hold it to put in a new bolt and nut. I did have to round the head off and run an extra nut down so it would sit good in the purch. I like the raked look better so I will either take it apart again and just reverse the next shorter one unless money free's up to do a mono leaf in the rear. I never had an issue above 60 mph but now I have a front end shimmy sense I did the flip. I mostly drive this locally but when I end up on the highway I end up only doing 60 =(. One last little thing, mny exhaust does tend to hit my rear on rare occasions. It sitts so much better, I can't go back to stock. Especially with a 2wd or I would raise it. Hope this helps.

 

My best advise, do as much research as you can before you go getting in to far. It is a pain if you are in your driveway, which I was! If you have the money, do a sid's dropped I beam or the mono leafs. This is mostly for the empty pocket people such as myself. Everyone's situation is different. My truck is family owned, I can't do too much to alter the originality of it. The best mod to do for the front end would be a doner crown vic and add the power steering rack. Just my two cents.

 

Thanks so much for the information! Also just my opinion, your truck my favorites that I have seen on this forum! My truck is my daily driver so do you think I should look at alternative methods of lowering it?

 

It truly depends on your budget... If I had the funds, I would do a mono leaf rear 4" drop and a sid's dropped 3" I beam in the front with new shocks. I get most of my stuff from Obsoleteclassicparts.com located in OK. Most orders are two days to PA where I am located. Napa surprising had most of the engine stuff, generator, belt and voltage regulator. ext... I have hopes to do that setup next year when I have the funds but if I really had not holds bar plus all the time in world to weld mock up and time, then the crown vic setup would ideal. That's not gonna happen LOL

Good Luck with it, keep me posted on what you do. I would love to see the outcome. Like I said, this was my third go around. \

Alright thanks man I'll be sure to show everyone what I end up doing, my truck isn't nearly as clean as yours but I've put almost all of my focus into the mechanical side of things and am just now really starting getting into cosmetic things.

One more question (for now), does your truck ever bottom out with the leaf flip method?

 

I'm going to resurrect this thread instead of making a new one, as there's some pertinent info in here already. My truck feels way over-sprung (non-scientific, seat-of-the-pants analysis) and I see there's a range of "correct" leaf amounts. I have a 65 F-250 4x4 with a set of Betts leafs all around. 8 leafs per wheel. Every bump in the road I hit sends me off the seat. I'm running Rancho 9000 shocks set mid-way. When you get a couple guys bouncing on the rear bumper you can hardly get the rear end to flex. I was thinking about subtracting a couple, giving me a more compliant ride, and in that more control, unless I'm missing something important here.

 

There isn't really a range of correct leaf amounts. What they had was different leaf packs that were used to achieve the correct load rating for the given truck. Sometimes a leaf pack has fewer leafs and a lower spring rating. Other times a leaf pack will have more springs and a lower spring rating, too.

Look at these two entries that ND posted. and note how in this case the one with 10 leaves has more capacity than the one with 11 leaves.

A common way that people use to alter their ride height or comfort is to alter the spring pack. Of course, nobody really knows how it will affect things until they do it and take it for a test drive.

I see Betts is still in business. You might check with them to get their take on it. Just a thought.

The proper way to alter an already altered vehicle is a tough question for others to answer in my opinion.
