Do these fenders require fasteners, or do they use the factory bed mounting holes?

These are designed to mount at factory bed attachment points, which minimizes drilling. Verify your vehicle's mounting hole locations before installation to confirm alignment. Additional fasteners may be needed depending on your specific bed configuration—check your OEM documentation.

What prep work is needed before painting?

Sand the surface thoroughly to ensure paint adhesion, then clean away all dust and debris. Your choice of primer and paint type will depend on your climate and desired finish—consult your paint supplier for compatibility with FRP substrates.

Will these interfere with jack points or bed access?

Since these mount over the existing bed sides, verify clearance around your vehicle's factory jack points and any tie-down locations before final installation. The bulge profile is designed to work with standard bed geometry, but your specific setup should be measured to avoid interference with under-bed equipment or accessories.
