Stock Lift BLocks?

Are these stock lift blocks?



I am looking for a stock lift block for my F150 with the 2-1/2" wide rear leaf pack. What F150 models were these found on?

What is the extension off to the side of the block for?

The F150's with the 2 1/2'' wide leaf pack are 2x4 F150's. The 4x4 models have 3 or 3 1/2'' wide leaf spring packs.

The extension off to the side of the block is what the bump-stop will contact if the rear suspension runs out of upward travel (for example, the bed heavily loaded then hitting a bump in the road).

The bump-stop keeps the suspension from completely bottoming out and possibly doing damage.

That looks like a stock block to me. I believe the aftermarket lift blocks don't come with provisions for the bump-stops.

Depending on if they have different width blocks to go along with spring width my 86 150 4x4 blocks look identical.
