The shock mounting plate?

4 inch block is steep.
Live with it dragging
Rework the shock mount
Go back to 2 inch blocks and de-arch the leaf springs

 

It don't drag there it is at the back of the spring shackle I don't know if this pic will help to see what I got going on

 

Well
Things drag when you sit low.
I got scars all over my driveway

 

It don't drag there it is at the back of the spring shackle

Mine got stuck lol

 

Been there.
Part of the low game
Just don’t leave it in neutral when ya get it un stuck

 

Put the bumper back on and drag it.
That will save the shackles

 

Better to drag the shock brackets than the Gas Tank.
