Frequently Asked Questions 

Rattle-Free Hitch

  • How easy is it to install my Rattle-Free Stabilizer?
    It only takes a couple of minutes to install a Rattle-Free Stabilizer. No special tools are needed and no modifications to your ball hitch or receiver are required.
  • How do I know which size Rattle-Free Stabilizer to buy?
    Our RFv2 is designed to fit a standard 2” hollow ball hitch. We offer a shim adaptor to allow the stabilizer unit to be used with a 2 ½” hollow ball hitch.
  • Is the Rattle-Free Stabilizer protected against rust and corrosion?
    Yes. We build our stabilizer using T6061 anodized aircraft aluminum and zinc plated grade 8 bolts, nuts and lock washers. We also apply anti-seize paste to the threads of the bolts during assembly to enhance corrosion resistance and to make the stabilizers easier to install and remove.
  • Why doesn’t the bolt on the Rattle-Free go all the way through the ball hitch and receiver like a standard hitch pin?
    A standard hitch pin is old technology that just loosely holds the ball hitch and receiver together. The bolt and serrated flange nut on the Rattle-Free Stabilizer draw the ball hitch and receiver tightly together on one side, effectively making them a single, much stronger unit instead of two separate pieces. Because we are pulling the ball hitch and receiver tightly together on one side, there is no reason to go all the way through the receiver.
  • Is the Rattle-Free Stabilizer stronger or weaker than the standard hitch pin that comes with most towing systems?
    The bolt, flange nut and lock washer system that we use in our Rattle-Free Stabilizer is more than 3-times stronger & more secure than the standard hitch pin.
  • How does the Rattle-Free Stabilizer reduce the mechanical stress on the towing hitch and on the transmission & drivetrain of the towing vehicle?
    The mechanical stress is caused mostly by the in and out banging of the ball hitch as the towing vehicle stops and starts. The in and out pounding of the ball hitch magnified by the weight of the trailer acts like a jack hammer pounding into the tow hitch and drivetrain. The Rattle-Free Stabilizer eliminates this problem by drawing the ball hitch and receiver tightly together which stops all back and forth, in and out, up and down motion of the ball hitch.
  • How does the Rattle-Free Stabilizer reduce trailer sway?
    The same way it reduces mechanical stress, by eliminating all motion of the ball hitch. As little as 3/8” – ¾” of side-to-side motion of the ball hitch can translate into a foot or more of sway out at the tires/axel of the trailer.
  • Do I need a separate Rattle-Free Stabilizer for each of my vehicles?
    No……the Rattle-Free Stabilizer is easily transferred from one vehicle to another.
  • Is the Rattle-Free Stabilizer lockable?
    No, and yes. The Rattle-Free Stabilizer does not come in a lockable version, but it is quite secure because it is very unlikely that a common, opportunistic thief will be carrying the correct size wrench to remove it. But, having said that, if you feel more comfortable using a lock we suggest that you use a padlock to secure your safety chain to the receiver.
