When you are looking at sliders or rails, you have to figure out what you are protecting and how it will work.
My rails did not provide a decent step nor did they protect the bottom at the pinch weld. if i got too close to a rock at 8" on
either side, it did well. But I lost clearance and didnt protect the bottom edge.

My advice to any noobs, find out what it does and how it is supposed to work before you add something to your
vehicle. I blew $300 on cust made crap. The welder did what I asked for, I just didnt know what I needed.
