Does this require drilling or modification to my bumper or frame?

No. This bolts directly to factory mounting points — no drilling, cutting, or frame modification needed. Your existing hardware and holes line up as-is.

Will this work if I'm installing an aftermarket front bumper?

Aftermarket bumpers vary. Some use the same mounting architecture as factory, others don't. Test-fit your new bumper against this bar before final commitment — compatibility depends on the specific bumper design.

What condition does this arrive in — does it need paint or prep work?

This arrives as a bare structural component. If your bumper cover sits flush against it, no paint is required. If any part will be visible, sand and prep it according to your paint system before install.
