They are not the same kind of product as the sliders, which is what Smitty is asking about.
I'll continue to disagree with this blanket statement that you have repeated elsewhere. It doesn't matter to me what product Smitty or anyone else chooses to use, but I think it's best to keep the facts
out there and let people make up their own minds based on their own needs.
products (and some others, too) protect the breakover angle and the full length of the rocker panel.
are designed to take the full weight of the vehicle.
I would humbly suggest that these are the primary goals of any product mounted in this area of the vehicle. To say they are "not the same kind of product" thus strikes me as a tremendously misleading statement without some serious qualification. Nerf bars like Huey uses now, RR's Super Sliders, RR's Rock Rails, 4xG's Side Guards ... they're all essentially doing the same thing.
Are they exactly the same products? Of course not. But are they the same types
of products? I'd say they absolutely are.
So what are the differences?
RR's and 4xG's products can be used for side jacking points (nerf bars aren't all created equal in this regard, but I imagine Huey's can certainly be used this way). I believe the Side Guards, however, are the only one of these products to have built-in gusseted slots that "hold" a HiLift-type jack in place; all the rest, on the other hand, only have a smooth surface to jack against. The difference here is that the smooth surfaces are liable to result in the jack falling out at the most inopportune and often dangerous time -- something I've actually seen happen on the trail.
2. RR's Sliders stick out horizontally further from the body, meaning that if your vehicle actually fell over sideways into a rock they'll do a better job than the Side Guards in protecting the body above the rocker panel. RR's Rock Rails do the least good in this regard. 4xG's product -- and some nerf bars -- are in the medium range. (Nobody makes a "stinger" that mounts on the side of the Commander!)
3. RR's Sliders and Rock Rails, as well as all the nerf bars I've seen, all mount off holes drilled into the frame. This kind of mounting means you're lowering your ground clearance at the breakover angle, which is already the weakest link in the Commander's off-road capabilities. 4xG's Side Guards are the only
product that not only doesn't lower this clearance but actually raises it in comparison to stock.
4. With the exception of RR's Rock Rails, all the products discussed here -- RR's Sliders, 4xG's Side Guards, and most nerf bars -- can be utilized as a step. They aren't all equal, though: all but the Side Guards are extended "tubes" one way or another. For many folks it's a non-issue, but as a dog owner I don't want a gap between the step and the vehicle. Too many pets have had legs broken by trying to clamber into a vehicle and having a paw slip through the slot.
Like all the accessory decisions we make, there's give-and-take. No product is perfect. We make our choices based on our own personal experiences and tastes. In all my years of Jeeping, I've never once dropped my vehicle on its side. If you do this regularly, though, you might want to get RR's Super Sliders (or, you know, drive better). While I'm always anxious to maximize my clearance, maybe you don't care. Maybe you don't have a dog and only care about having a really low step. So then perhaps you'll choose a product that fits that route. Maybe you just like the looks of one product or another. So go with it.
I just want everyone to be able to make their own decisions with all the pertinent facts in hand.
