Chrome-moly impact-rated step-down adapter: 3/4 inch female to 1/2 inch male, with detent ball and pin hole. Lets you run 1/2 inch drive sockets off a 3/4 inch gun or breaker bar. Easy to overpower 1/2 inch sockets this way, so go gently on the trigger.

Chrome-moly impact-rated step-up adapter: 1/2 inch female to 3/4 inch male, with detent ball and pin hole. Lets you run 3/4 inch drive sockets off a 1/2 inch gun or ratchet. Mind the torque — stepping up doesn't give the smaller drive more muscle.

Black-oxide impact-rated socket, 1-1/2 inch, standard depth, with a retaining-pin hole. The kind of size you need for big suspension, trailer axle, or heavy equipment fasteners. Drive size isn't confirmed from the photo — ask before you make the trip if it matters.
