These seem like a really good idea on the rocks. I'd think that they would move over rocks a lot better than a solid diff cover. Any personal experience would be appreciated.

 

I am joing in. I would like to know this also. Even though they hang down a little more than the diff itself, I think they would work much better than just a heavy duty diff cover.

 

Personally your housing is very strong and these imho will just lower your ground clearance and not help. The whole point of a lift kit is bigger tires, higher ground clearance and these take away that clearance . In the picture they appear to hang down at least an inch or more.

I agree that if they take away ground clearance, then they defeat the purpose of larger tires. I would hope that the .25" steel is right against the bottom of the diff.
Hopefully someone here has used them before, and they can shed some light on this.
If they take away ground clearance that's a deal killer. I'm also wondering about how tough they are. Do the last?
Assuming they last, and that they are up against the bottom of the diff, I really like the idea of the glider sliding over a rock, rather than the bottom of my diff.

 

They look thin.... If your worried about the diff cover catching then go with the riddler ones as they are smoothest iv seen. The aftermarket diff covers are a proven product, they really don't need any improvements. I have never heard of an aftermarket diff cover breaking.

 

It may take away a tiny bit of ground clearance, but it looks to provide a more uniformed surface to go over obstacles. I could see them working well, but my thoughts are based off of design in the picture posted, not real world use.

 

I guess his point is that if your even 1 inch lower thats more obstacles that you will have to slide over, just a regular aftermarket diff cover will do the job so why sacrifice the 1" clearance? Another thing I just thought of... What if you hit something really hard and bend your tie-rod to the point of it bending your diff cover? Far fetched I know but id rather replace a tie-rod then tie-rod, diff cover, and broken gears. Would it work? Yeah it looks like it would. Any better than armored diff cover? No I dont think so.


However if you plan on hitting water at high speeds this may create a little more lift to keep you above the water.

 

My wife won't let me have a jet ski, so this might be the next best thing.

I don't have firsthand experience with the Rock-It sliders, but I have used something similar. I installed Con-Ferr differential skidplates on my '93 YJ. I don't know if they even make them anymore. They were sort of similar to the Rock-It's, and they worked very well for me. The decrease in ground clearance was minimal. They got pretty scraped up underneath, but I never had any differential issues, so I guess they did a pretty good job protecting the diff's. I considered using the Rock-It's on my JK, but I decided to go with something different. I can't thik of the name of the one's I got right now, but they're made of tubular steel and bolt to the holes on the lower part of the stock diff cover.
