Comparing Add-on Friction Sway Control to Equal-i-zer 4-Point Weight Distribution System

Question:

I do not need weight distribution since I am level when my 30foot 8k trailer is connected to my chevy 2500. I am looking for sway control. I am considering the Equalizer and the Andersen no sway hitches. Which in your opinion would do the best to control sway? Thank you.

Add-on friction-style sway control units like # 83660 and the others shown on the linked page can provide a degree of sway reduction without adding an entire weight distribution (WD) system. You can even use two of these at the same time, one of either side of the trailer. These help limit sway once it starts but they do not deliver the same kind of sway control as a system like the Equal-i-zer 4-Point Weight Distribution System # EQ37140ET which works to prevent sway before it can start.

Using a properly-rated WD/SC system like the 4-Point will provide not only reduced trailer sway but also will tend to improve steering and braking performance by putting a bit more weight on the truck's front axle. Even if your truck is level now, shifting some trailer tongue weight (TW) forward to the front axle will provide improved handling.

You want to measure your trailer's actual loaded TW and to that add the weight of anything I the truck bed that sits behind the rear axle. With this total TW known you can choose a system. Ideally your total TW will fall right in the middle of the system's operating range. For instance, the system you referenced, part # EQ37120ET, works for TW ranging from 800- to 1200-lbs so a total TW of 1000-lbs would be ideal. System # EQ37140ET would be ideal for a total TW of 1200-lbs.
