I have a sagging rear end what would be the best and easiest way to beef up the rear shocks. Thanks Jeff

 

You most likely need new springs.
Shocks dampen the springs movement. They only carry a small amouny of weight.

 

how do i know what springs to buy. Jeff

 

Year and model.
GVW may affect it.

What do you intend to use it for?

A truck that is used to haul leaves and the occasional appliance will be better off with a softer spring. A truck that is used to haul construction materials or pull trailers would benifit with a stiffer spring.

 

You can also have your existing springs re-arched to proper ride height. A shop that specializes in heavy truck springs can do it. New would probably be better, but if they can't be found, this is a viable alternative.

 

Im sorry its a 1965 f-100 and ill be useing it to haul firewood 1/2 cord at a time dirt for the yard stuff like that. So if i go with new leaf springs where would i get them and what kind. Thanks Jeff

 

I do not know where to get them I guess. LMC sells them for a 65 F250. Try seeing if they are the same size as the F100.

Depending on how bad the sag is You may be able to just replace all the bushings and add a helper spring set. They vary in cost from about $80 to about $300 depending on quality and load capacity. If you have any broken leafs you need new springs however. The 60s had factory helper springs available. I have them on my 64 which is a different chassis entirely.

My trucks basic springs will only give about 1.5" clearence between the helper and its strike plate. However......I can load a cord of wood on her and she only sits down about 3" total. That helper can hold a ton.

I would ask around I would see if Numberdummy can swing a ford PN as he may be able to cough up a set. You cant PM him yet but hopefuly he will stick his head in on this one. Another user may have a idea where to locate them also.

 

I got currious and found this in my NPD catalog........

For a 1965 f100 2WD.....

A 950# spring is $199.95 NPD part #F-5560-15
A 1650# spring is $324.95 NPD part #F-5560-17

If you plan on doing any significant hauling I would get the heavier spring. The stiff ride will be worth it with a bed full of dirt. A softer ride and some added load could be gained by adding an aftermarket progressive rate helper spring. They generaly add about #800 to the overall capacity though they are very noisy as they tend to rattle when the truck is unloaded.

I hope this helps. Though, there may be other sources out there.

 

Jeff8362000,
Have you called your local NAPA or tire supply store?
If they can't get them for you then ask them where you can get them.
I'd try to find a source locally, otherwise the shipping costs are going to KILL YA...

Wherever you find them, make sure to ask about the eye bushings. Some folks supply them with the leaf springs and other sources do NOT supply the bushings with the springs - so they are an extra cost.

If you decide to go with the heavier leaf spring pack, compare their stack height to your current stack, as you may need to buy larger/taller U-bolts to hold them to your axle.

It's a good time to replace the shocks too, since you'll have one end off already and they won't be any easier to get to with the leaf springs out.

Good Luck!

F250 rear springs are not the same as F100 rear springs.

F100 2WD rear springs are not the same as F100 4WD rear springs.

C5TZ5560A .. Rear Spring / 5 leaf / 950 lb. load rate / Obsolete.

Fits: 1957/72 F100 2WD.
------------------------
C5TZ5560D .. Rear Spring / 9 leaf / 1650 lb. load rate / Obsolete

Fits: 1957/72 F100 2WD.
-------------------------
C5TZ5560N .. Rear Spring / 6 leaf / 1250 lb. load rate / Obsolete

Fits: 1957/72 F100 2WD.

AITKEN MOTOR CO. in Aitken MN has ONE = 218-927-2169.
---------------------------------------------------------
No other Ford Dealer, no obsolete parts vendor has any of these springs.

JC Whitney used to have these springs, dunno whether they still do...or not.

FTE member AirHarley is a NAPA partsman, posts in this forum. Y'all oughtta contact him.

 

So all 57/72 2WD F100s use the same rear leafs.

 

That's correctamundo, because...C5TZ5560A replaced B7C5560A.

C5TZ5560D replaced B7C5560C, and C5TZ5560N replaced B7C5560D.

 

Bill,
Does your data provide you with the physical differences between the F100 and F250 leaf springs ; such as thicker, wider or longer etc. ?

Would you please list the data for the '65 F250 2WD leaf spring packages that were available?

Thanks!
BarnieTrk

 

If i get new leaf springs what do i tell the auto store. Is there any year at all that would interghange . Thanks Jeff

 

57-72 F100 springs are all the same dimension.
