Default Bump Stops: Fox IFP or King

Are the Fox IFP bump stops better than the King bump stops? Is the tech inside of the Fox IFP stops better than what's inside of the Kings? I'm trying to figure out what makes the Fox IFP stops more expensive than the Kings. Any opinions would be appreciated. I'm about to invest in front and rear.

The fox have an internal floating piston (IFP) that separates the oil from the nitrogen. It something nice if you are desert racing but totally not needed for 99.9% of JK's Fox just knows if you make it for a JK some idiot will buy them and bolt it on their rig. If you don't understand what an IFP is then you really don't need it.

Oh, ok. Thank you for explaining that to me. So here is the deal, then... I have all Fox shocks already. If I went King bump stops, my OCD would get the best of me cuz they don't match! Haha! And I don't know if they is true but my buddies seem to think Kings bumps are better, except when it comes to Fox IFP. They all have King.

So then should I just get the regular Fox 2.0 bump stops? They are significantly less, like $400 for front and rear. Kings are about $600 for front and rear, but then I just noticed that King also makes a hydraulic bump stop for about $1100 for front and rear.

I don't know where I should spend my money.

I really doubt you need bump stops so what ever fits your budget. You are not going to be able to tell a difference between the standard and the IFP unless you are desert racing the Baja.

You really need more than 1.5" of between the bump and the pad. What pressure is in the bumps?

They all do the same thing. Agree most JK owners don't need them, but they are functional and look cool. If you have money to blow on them them go for it.
