Frequently Asked Questions

Which is tougher: Armor Flex or Ultra Flex?

Armor Flex delivers extreme dent and scratch resistance with Line‑X coating; Ultra Flex adds LED rails and a quieter ride.

Can any cover be installed without drilling?

Yes—all hard folding and one‑piece covers use clamp‑on rails—no drilling into bed rails.

Will LED lights drain my truck battery?

LED rails and one‑piece battery lights use low power. Disconnect or remove battery pack during long storage.

How much weight will these covers support?

Armor Flex and Ultra Flex support up to 400 lb evenly; Elite one‑piece covers support cargo and ladder racks too.

Is UnderCover made in the USA?

All covers are manufactured in Missouri, with body‑shop tested prototypes and in‑house tooling for precision fit.

How does SwingCase work?

SwingCase is a bolt‑in toolbox that swings out nearly 180° and holds 75 lb—ideal for gear access without climbing into the bed.

Is clamp‑on installation secure?

Yes—UnderCover’s rubber‑sealed rails and tight clamps make fast, tool‑free installs that stay put mile after mile.

What warranty covers these covers?

Hard folding covers carry a 5‑year limited warranty; Flex carries 3 years; one‑piece and SwingCase covers vary—visit product pages for details.

How do I care for my cover?

Use mild soap and water. Avoid pressure washers near seals. LED rails and ABS are durable but clean carefully.

Can covers be removed easily?

Absolutely—clamp‑on or bolt‑in rails allow teardown and reinstall in under an hour with basic tools.
