OEM lift block..have 1.
 

Got springs for my project, and was able to find one lift block. it is 3.75-3.5" tall, tapered, and has OEM ford casting numbers on it.
What are lift blocks officially called? I cant find the category on car-part.com

if anyone can help me track down the passenger side of this block I would greatly appreciate that. Dont want to pay 80 bucks for blocks when Im sure i can get just the one for 10 bucks used.

or if someone has a pair of 3 or 4" blocks for sale PM me!

This came off an 08 f350

You used to be able to buy the tapered blocks individually, I'd assume you still can:
Left Tapered Block: F81Z5598FA
Right Tapered Block: F81Z5598GA

It's officially called a "spacer".

i seen that, but theyre 60 bucks a pop from the dealer! :0

gotta call soem yards see what they come up with. no listings under spacer, axel spacer, spring spacer, block or anything like that online.\

also i dont think the PN you listed will work with the one i have. says to 01 only. I mean-its an OEm block, but i need to know the taper of the one im buying..and it dosnt give the height of it either
