Suspension enhancement is great for vehicles that are carrying a heavy load in the cargo area of the vehicle. But if the sag is from towing a trailer a much better solution is a weight distribution system. This will take the tongue weight of the trailer and partially distribute it to the front axle of the vehicle which will give it better braking and handling characteristics that with suspension enhancement.

The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready to tow. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. I attached a help article on determining tongue weight for you to check out as well. You will want the loaded tongue weight of your setup to fall right in the middle of the tongue weight range of the system you use.

Once you know your tongue weight you will want to check out the link I attached that has all of the weight distribution systems we carry. You will be able to select your tongue weight from the filters to see what would be rated for your setup.
