Ranch Hand Bumper and Winch weight

[Coolbikr4684]

So I installed a ranch hand bumper (300lbs) and put in a m15 warn winch (100lbs). I had no problems before the bumper now my front tires are feathering on the outside. When I do a search it says add a lift but I'm planning on buying a fith wheel so I'd like to keep stock height. My question is. Do I need stronger springs, shocks, more or less air pressure in the tires, or an alignment? I'm not sure which direction to go. I have a 2018 2500HD 4x4 with Toyo Open country A/T 285/75R18. Thabk you all for any suggestions provided.

I’d rotate then get a alignment to Thuren specs.
