Do these caps bolt directly to my factory bed rails?

Yes. These mount at your truck's factory rail attachment points — no drilling or frame modification required. You'll need bolts and washers to secure them; verify bolt size and grade against your truck's service manual.

Can I use the pre-drilled hole for a tonneau cover or bed cover?

The hole is ready for tie-down hardware or accessory mounting, but compatibility with specific tonneau systems depends on that cover's design. Measure your cover's attachment points and verify hole spacing before final installation.

What's the return policy if these don't fit?

Verify your bed length is 6'6" before ordering. Once installed and bolted down, fitment issues may incur a restocking fee — test-fit on the truck before fully tightening all fasteners.
