I am getting a set of rear springs from a 2002 f250 2wd diesel. There wasn't any tag in them and the door sticker was long gone. If my memory serves me correct there are 4 main springs and a top overload. Does anyone know what springs these are.

Also can I use the top overload bump stops and bolt them or weld them onto the excursion?

Also is there any difference between a rear 250, 350 and X block. I would like the biggest lift using factory parts.

 

The springs should be a 4/1 (4 leafs in the main pack over a thick one the bottom) with a possible overload spring that sits on top, either bolted to the main set of springs or sits on top and held down by U-bolts.

Tough to say exactly without doing some certain measurements but the main spring pack may be a B code.

That's exactly the setup on these springs

 

F350 blocks come in at 3.75" where F250 and Excursion are around 2". Here is a thread all about the blocks. Be aware there are two types tapered and flat. Look for post #22. Depending on wheelbase length detemines what is needed.

 

I recall someone saying not to use the upper overload springs as they'll contact the rear A/C hoses on the passenger side.

Plenty of info in the tech folders.

Do you have the vin? If so, I can tell you what it was built with. Also there should be a part number on the spring itself, supposed to be stamped on the last leaf. I can tell you from either one.

 

Good info there. Thank you.


Thanks. That's what I figured but wanted to double check

 

I do not have the vin. The body is long gone. I didn't see any number on the springs but they were dirty and it wasn't very light out. Once I get them I can look closer. The springs will still be on the truck for another month or so until the chassis is finished being stripped.

 

Hey Rob Ross-
Here's one for you (please!)
Rear leaf springs "RPN 3168 F81A BE
Thanks!
Sorry for the thread jack!

 

I'm on it, I'll report tomorrow am.

(Also sorry for the thread jack)

 

F81A 5560 BE is a B spring. It's just an earlier part number but the specs are the same.

 

Are you able to do this with front springs? If so what would these be

YC35AMARPN0150

 

YC35 5310 AMA is a V code.

 

that's awesome I picked them up for next to nothing, but I don't a the 5310 anywhere is that no never mind it still decodes to a v?

 

Also thank you for the quick response
