quick question and I've been searching for a straight answer and couldn't find it. You know that rear block underneath the leaf spring on your 4x4 F-150, that the 2wd doesn't have? What size is it? I've read it is 1 5/8" and I've read that it's 2". Could someone please go outside to their truck with a measuring tape and check for me to verify which size it is? Thanks.
Another thing, I got confused cuz I also see that auto spring says the stock block is 1 5/8" and they have a 1 1/2". And other brands sell a 2" block.

 

hmmm i thought it was 4in block, but its too dark outside, Ill take a picture tomorrow.

 

1-5/8" sounds right.

 

I had been saying 1 5/8's, and I thought I measured it that way.
But I just ran to the garage to verify, it is definitely 1 7/8's - 2".

 

4" block stock. 4wd's must be huge stock! im not help don't have my stock block any more

 

ohh right, isnt it a 4 in block in the back with a 6in lift?
I think i just confused myself.

 

I just measured --- my '07 has a 2" block.
