This particular set, contained in the familiar SAC blister packaging, is a perfect match for the SAC metal Landing Gear set 48472 for the F-35 C. See the excellent review by Rod Lees.
There are two parts — each representing the right and left-wing hinges. Upon inspection, no flash is detected, and they are cleanly cast. As with all SAC products, the pewter is pliable and can be adjusted as needed for a perfect fit. The two SAC parts are designed to replace kit parts EE39 and EE38, discussed in steps 61 and 62 within the Tamiya instructional guide.
Although I am a fan of metal landing gear for increased strength and stability, replacing these particular kit parts is negligible, in my opinion. Viewing the kit parts side-by-side with the metal parts, I found the kit's parts to be crisper. For this reason, I would be more inclined to stick with them, especially since the wing hinges are not parts which really require increased strength.
