Honestly not sure, that’s why i wanted to check. I’ve heard most people recommend a maximum of 3/4” spacers, so i was wondering what the downsides are to a larger spacer.
What size spring spacers do I need?

Nothing noticeable. I align my front end after any height changes FWIW.
.75” is supposed to compensate for sag of a new steel front bumper and winch. From looking at your picture, you should probably run a 1”. Which front shocks are you running and what are their lengths at ride height?
I’m running the Rancho 5000x. I don’t know the ride height length from the top of my head but i can measure it and let u know
Alright just an update and consult before purchasing some spacers.
I measured the height in the front while it sits on a flat surface, and got 26.5” from the ground to the front bumper. I then put a jack under the front frame crossmember and jacked it up until it looked level and how i would want it to sit. I measured again while it was level and got 29”. So i have a rake of 2.5”. To compensate for some weight in the back such as camping gear, it seems as though i should run a 2” spacer up front, which seems like a lot.
Did i measure this correctly?
And will i have any issues running a 2” spring spacer up front?
Here’s a before and after of the rake and how it looks with a jack under the front.

Good approach to getting the exact difference you want in the front.
With a 2" spacer, I'd search around on the forum to see what else (if anything) you'd need to change as a result in the additional changes to your geometry. If I'm reading you correctly, that would give you a total lift of 4.5" in the front? So what other changes are necessary at that lift height?
If it were me, and I were looking for 2" of difference, I'd consider other springs. 2" seems like the max for a spacer, IMO.
p.s. Actually, by raising the cross-member to the desired level, you cannot assume that the difference in bumper height (before and after) is equal to the necessary difference in spring height. I suppose that under some circumstances those two numbers could happen to be equal, but I think that'd be rare. Instead, I'd recommend measuring the spring length before and after raising the bumper to your desired height. My guess is that you'll get a different number, and likely a smaller number.
The less change in ride height after a change in weight, the higher the spring rate.
At some point, too much spacer will lead to coil bind at full shock compression. That amount depends on the specific spring and the specific shock.

Wow just remeasured at the springs and got 1.25” this time. So this is the measurement i should use? Not the one from the bumper?
Yep! That tells you that by increasing the spring length by 1.25", you get a 2" difference at the bumper.
