Need help What lift is this?

I recently purchased this truck. It has a lift but I'm not sure if it is a 4" or 6" lift. This is my first lifted truck and I'd like to know what are my options for combinations is shocks and struts when I replace these.

 

Betting it’s a 6 inch being it’s a 4 inch block in the rear

 

Don't forget the spring spacers on front coils.

 

Appears to to be a 4 inch lift with pucks (in front) and blocks (in back).... aka a spacer lift with a drop bracket. The shocks appear to be Rancho.... afaik. They are the only manufacturers of a white body housing. The yellow one in the front is a bilstein 4300.

 

nice looking truck.
