I unfortunately got some damage to my hinges before I did anything about it.
I then installed some rockblokz front and back and they made a huge difference.
so much do that when I got 37’s installed I got the XL Rockblokz.
Anything that stops the rocks flicking up will help. Sjbiss’s rock sliders would be great for this too.
I also want to prevent flicking rocks up at others so mud flaps on the rear was important to me as well.
The rockblokz can be ordered with or without(I think) cut outs for the stock rubicon sliders… something to keep in mind if your going to get both.
I have zero association with rockblokz, I’ve just used them and was happy with them - any mud flaps with decent coverage would do.
