2020 Ford F-150 Suspension Upgrade to Help Reduce Sway

Whenever you tow a trailer, or put a lot of weight on the rear of your F-150 the leaf springs start to flatten out, and typically the ride geta very stife. Not to mention the sag in the rear end. The back goes down, and the front raises up. Which leads to less traction on the front tires, reduced braking and porpoising.

To help the sway and bounce when towing your trailer I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit. For 2WD # RAS3611-B, and for 4WD # RAS3611-Y.

This kit converts your F-150's leaf springs into an active suspension system. It will actively strengthen your leaf springs for improved ride quality whether you're towing or not. Once the suspension is loaded the tension springs activate and support the weight, this allows your leaf springs to stay in the bowed position and prevent them from flattening out, which reduces their capability of support a heavy load and can cause wheel hop and other unwanted things. The tension springs have a variable rate, which means more weight the more they support the factory leaf springs.

When you're not towing the tension springs disengage allowing your leaf springs to perform like they should and not stiffen the ride. That's why I really like this system, it doesn't effect normal driving, but it gives you the support and control you want when towing.

As far as the installation goes, there's no drilling or cutting required. They come fully assembled and bolt onto the factory leaf springs. Once they are installed there's no maintenance required, just hook up and enjoy your truck and trailer.

I linked the parts and a video of the active suspension system for you to check out.
