What you get in the package is a full gear replacement in white metal for both main gear legs and the tail gear. In many cases SAC will assemble some of the kit parts prior to casting. In this case the replacement parts number is the same as the kit parts. They have cleaned up the gear and filled any imperfections that were present on the original plastic parts. They also have enhanced the level of detail on the gear well above that of the plastic parts
The gear in the kit consists of five plastic parts. The metal replacement parts make up five pieces, two for each main gear and a single piece for the tail gear.
Detail is crisper on the metal gear than on the kit’s plastic parts. One can also tell from the photos that the SAC gear is much beefier, especially on the main gear retraction arms. The replacement parts are a drop fit with no issues what so ever. The overall appearance of the replacement gear is vastly superior to the kit parts.
