Slimline bumper on stock suspension

Is anyone running one on stock suspension? I just received one with a 10k winch with synthetic line and I’m trying to figure out if I need to do anything to the front end.

 

Not a slimline, but I added 175lbs to my front end with a winch/mount and front steel skidplate. My front dropped about 1" on the stock suspension. At minimum you'll need some adjustable 5100's set on the middle notch (3rd gen 5100's) to get the height back. That's what I'm running now.

 

I've got the same setup as you, SSO slimline, 10K synthetic winch, plus I have a full set of steel skids. I didn't take any measurements, I'm sure it has sagged some, but it certainly isn't noticeable to the naked eye. Behind the wheel I can't really feel the added weight either. Will I eventually upgrade suspension? Absolutely. But I don't think it's urgent or necessary right away.
