The stabilizer is designed to work with our carriers to reduce sway and rattlers.  After it is assembled no wrenches are required to use it.  It is more convenient to use and quicker to install than the anti-sway device.

When used upright on hitches with a 300 pound of higher tongue weight rating and tightened against the bottom of the hitch, it strengthens the carrier where it goes into the hitch reducing stress on the hitch and increasing the capacity of the carrier from 75 pounds to 120 pounds.

The stabilizer can be used with smaller hitches or smaller vehicles, but in many instances will need to be turned sideways for ground clearance.  The extra strength is reduced when used on the side of the hitch, but the carrier is stronger than these smaller hitches without the stabilizer.
