Added drop shackles and removed the blocks to lower the rear end, what next?

Added drop shackles and removed the blocks, short of axle flip or notching the frame, what's the next step lower the rear and level the truck?

The only option is to axle flip to give you a 4 to 6in rear drop.

 

You'll have to cut the stock bump stop bracket off the frame when you do an axle flip and install air bags if you want to tow with it.

 

I suppose you could remove one of the overload springs on the leaf spring pack to lower the rear as well. But then you have to watch out for axle wrap under full throttle. It'll wheel hop pretty easy doing that without a set of traction bars to keep the rear axle from swinging forward and up.
