It’s fine on an s3. I have the rear set on high as I’m mullet, but not sure it that changes anything. I done plenty of big drops and used all the travel with no issues at all. Its actually smaller than the float x that came on it.
I have the 2023 RS Super Deluxe Ultimate (air) on my s3 KSL and it clears the frame perfectly. I think the reservoir on top is the same across air and coil.
