With 500lbs you’ll definitely want different springs in the rear
I did eibach hd in the rear, it adds 2.5” to the height. Stock springs up front. I run a second spare, a badlands jack, shovel, traction boards, a 17” Blackstone griddle, a Roam case, a couple of chairs, and even an umbrella (don’t make fun of me, it gets hot in Utah and the Arizona Strip). There is still an inch to inch and half rake. I think geisers are rated for more weight.
Once you add the springs don’t forget to reset your live valve settings.
You’ll have a ton of fun in Baja with the Exo crew. They know how to do Baja
Not the best picture but this is how it sits with all the weight and eibach hd rear springs
