How often are you actually servicing/replacing armor - maintenance reality check

You're not being paranoid at all - armor maintenance is real and most people don't factor it into the total cost of ownership. I pull my transmission and transfer case skids every oil change now because I learned the hard way that packed debris can actually cause more corrosion than no protection at all.

My maintenance schedule: inspect slider mounting bolts every 3 months, remove skids for cleaning every 6 months or after any serious mud/water crossings. It's a pain but beats replacing drivetrain components. The CBI stuff is built like a tank but even tanks need maintenance.

Hairline cracks in sliders are pretty normal if you're actually using them. I've got C4 Fabrication sliders that developed similar stress cracks after about 18 months of moderate trail use. Had them welded up by a local shop for like $80 and they've been solid for another year since.

The key thing I learned is that functional damage isn't always failure - those cracks are the armor doing its job by absorbing impacts that would otherwise go to your frame. Worth monitoring but not necessarily worth replacing unless they're getting significantly worse.

This is exactly why I went with a partial armor setup instead of full coverage. I've got front and transmission skids only, no sliders or rear protection. Yeah, I'm more vulnerable in some scenarios, but the maintenance overhead is way more manageable.

I think there's a sweet spot where you protect the most expensive/critical components without creating a maintenance nightmare. My setup takes maybe 30 minutes to remove both skids for cleaning, and I can actually see what's going on under there during regular maintenance. Sometimes less is more, especially if you're not doing extreme rock crawling every weekend.
