Do these caps require any prep work before installation?

Wipe down the mounting surfaces and rail area with a clean cloth to remove dust and debris. If paint or finish looks compromised at contact points, light sanding ensures a solid fit. No special primer or coating is needed before install.

Will I need additional fasteners to complete the install?

These mount at factory rocker points — no drilling or extra hardware required. Verify that mounting tabs align with your truck's rail before final tightening; test-fit first if you're unfamiliar with your specific bed configuration.

What's the return process if these don't fit my truck?

Confirm your bed style is Fleetside before checkout — that's the make-or-break fitment detail. If they don't seat properly after test-fit, reach out to ModSupply with photos of the gap or misalignment, and we'll handle it from there.
