If this is not correct, I welcome any correction or better explanation from Blue Ox… but I don’t really expect any. This is not sway control by absorbing energy and thus damping the oscillation it affects sway by applying a return-to-centre spring force. Since the chain on the side toward the sway is angled to pull the trailer rearward, and the chain on the other side is angled to pull it forward, the horizontal component of the chain forces should tend to pull the trailer toward straight. I assume that Blue Ox’s intention is that with the spring bar pivots inclined back, and the bars skewed outward (due to the trailer tongue angle) when the rig is straight, a deviation from straight ahead (yaw) will decrease the spring deflection on the side the trailer yaws toward, and increase it on the other side.

While the bar pivot axis is usually vertical, the spring bars of the Bue Ox SwayPro are pivoted around an axis inclined significantly rearward (at the top) they appear to be calling this the caster angle.

This not only ensures a proper setup but allows for stress-free towing experiences during your adventures on the road.

When the hitch relies on friction points to control trailer sway, and the surface of these points get wet, the effectiveness of the hitch drops dramatically.”Īlthough RVers don’t need a physics degree to install a weight distribution hitch, its best to consult a towing expert. “This means RVers can use them in all types of wet weather. “The great thing about sway prevention weight distribution hitches is they don’t rely on a friction device to control the trailer,” says Kauer. Regardless, either model still offers a high degree of road safety and you’ll avoid a potential trailer sway wreck. While a sway control hitch brings the trailer back under control after it starts swaying, a sway prevention hitch doesn’t allow the trailer to sway at all. These include sway control hitches and sway prevention hitches.Ī properly set up trailer and tow vehicle. And, according to Kauer, there are two types of weight distribution hitches available that incorporate anti-sway devices. Most of all, weight distribution hitches help minimize dreaded trailer sway. This provides a smooth comfortable towing experience.” Weight distribution hitches and trailer sway The bars provide the weight equalization, meaning that when the pressure is applied to the bars in an uplift motion, it lifts the tongue of the trailer and the rear of the tow vehicle up to level. “Essentially, the hitch ball is set according to the coupler height and according to the trailer. “The mechanics of any weight distribution hitch includes a hitch head, trunions, bars and latches,” says Rick Kauer, Field Sales Representative of Blue OX, the manufacturer of the popular SwayPro weight distribution hitch. It also provides a smooth, stable ride, easier steering, and extends the life of your tires. This allows RVers to tow their trailer level. Rather than the rear axle of the tow vehicle taking on all of the weight of the trailer, a weight distribution hitch transfers the weight evenly across the frame of the trailer and the frame of the tow vehicle. In simple terms, a weight distribution hitch corrects all of this.

In fact, weight is the number one factor to consider when it comes to towing any travel trailer. Photo courtesy of retrocar66, member Why do you need a weight distribution hitch? Rather than the rear axle of the tow vehicle taking on all of the weight of the trailer, a weight distribution hitch basically distributes weight to axles of the tow vehicle and the trailer.
