If you are still getting a lot of rear sag on your 2018 Chevy Suburban Premier when hooked up to your trailer the first thing I recommend doing is simply checking to make sure your existing weight distribution is both properly rated and correctly adjusted. It is important that your setup's total tongue weight, which includes the loaded weight of the trailer along with any additional cargo weight coming from behind the rear axle of the Suburban, falls comfortably within the system's operating range.

If you can tell me what weight distribution system you have I will be happy to verify its rating and make sure it's appropriate for your setup.

If all of that is good then you can work to bring the rear further up towards stock height by adding a set of rear air bags. If you have the Premier 1500 model Suburban the Firestone Coil-Rite Air Helper Springs # F4108 will work great. These will fit inside the factory coil springs on your vehicle and their adjustable air pressure (5 to 35 psi) will let you reduce that sag when the trailer's hooked up but also maintain a comfortable ride when it's not.

I have attached an installation video that you can check out as well.
