Yes, the front and rear springs in the photo are part of the package.
Now that you mention it, I should measure the arch.
Those could be a 2-4 inch lift.
The rear spring plates are junk, you will need to find some new ones.
The blocks are 4".
Heavy duty compared to the Tuff Country I bought, but I wanted a really soft ride.
The truck is on my project build with those springs and blocks under it.
