The SC is similar to the Fastway E2 with just sway control points at the spring bars and hanger. Probably not as good as the Equal-i-zer 4 pt. that has both the spring bar and hanger friction, as well as a damper at the spring bars and hitch.
The unit in the link handles up to a 600 lb. tongue weight......make sure your trailer tongue is under that weight.
