Well, you can bust an air line on the trail and have a fun time fixing it, kill some wires? Easy splice! But I do agree everyone needs some sort of an air system.

You're right. If a inexperienced person throws in the air lines and is a idiot while doing so, you can get them ripped off. Just like your fuel lines, brakes lines, etc...

Now do it like you should and Install them intelligently, there is NO way your "ripping" any air line off, or cutting it, or rupturing it, or "blowing" it out... Unless you rip out a front housing, or upper control arm, or brake line...

Which actually happens a lot. Maybe not on what most people do, but it does happen. You are offering to sell a zip locker, are you also going to professionally install it? A full case locker isn't difficult to put in, so people on a budget will try to tackle it.

Besides, the OP asked about E-Lockers, not air. But if the OP changes his mind, ARB FTW!
