gen 2 towing capacity

Hey I’ve got a 2018 SCAB. I’ve done Eibach springs up front and currently have Icon Multi rate springs in the rear set at Option 1. The truck is level and looks and feel great but when I tow anything it gets sloppy. I want to retain the look I have but tow a little better. What I was thinking...

I’m new to the Raptor world so forgive me if this has been asked previously. I read in the owner’s manual that to tow the max of 8200# modifications must be made. What type of modifications have to be done to a stock 2018 to tow this maximum? Thank you in advance for your help!
