Scale Aircraft Conversions is a maker of metal landing gear to replace kit parts. This landing gear set is for the Hasegawa 1/48th SH-3 Sea King. Included in the set you get two main landing gear struts, two retraction actuators, two torque links (scissors), and the tail wheel.
After comparing the kit parts to SAC’s parts this is what I have come up with. SAC’s gear will give your model a firm base to sit on. However, there are also some shortcomings. The SAC gear appears to be a tad bit smaller (see the photos below). This may not be an issue because who can say that the kit gear is correct? One area that will be an issue is the retraction actuators. As you can see in the kit and SAC comparison photo, the SAC actuator is just short of contacting the gear strut.
