For your 2019 Jeep Grand Cherokee with Quadralift suspension I have a solution that will help with rear suspension sag similar to air bags if you plan on towing a trailer but none of the air bag kits we offer are a fit for the models with the Quadralift suspension.

So instead your best option is a weight distribution system. These kits reduce the rear sag like an air bag kit but what makes them superior to air bags is that they also improve handling and braking due to redistributing some of the tongue weight from the trailer up to the front axle of the tow vehicle.

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.
