Hard Covers and Elite LX

Elite LX covers use a painted hard-shell design for owners who want a refined, color-matched truck bed lid. Confirm the exact truck generation, bed length, tailgate configuration and any factory bed management system before ordering.

Ultra Flex and Armor Flex Folding Covers

Ultra Flex and Armor Flex covers use low-profile folding panels, weather seals and clamp-on rails. These covers suit owners who need secure cargo protection with practical access to the bed.

SE Covers and Truck Bed Storage

SE hard covers and SwingCase toolboxes add secure storage without sacrificing daily truck utility. SwingCase units mount at the bedside and should be selected by the correct driver or passenger position.

Fitment and Bed Measurements

Truck bed cover fitment depends on year, cab, bed length, bed rail style, cargo management features and tailgate design. Measure the bed and review the product application before purchase.

Common Questions

Which trucks fit Undercover tonneau covers?

Undercover offers vehicle-specific covers for many Ford, GM, Ram, Toyota and Nissan pickups. Confirm the year, model and exact bed length on the product page.

What is the difference between Elite LX and Ultra Flex?

Elite LX is a painted hard-shell cover while Ultra Flex uses folding panels for easier bed access. Choose the style that fits your cargo and finish preferences.

Does an Armor Flex cover require drilling?

Many Armor Flex applications use clamp-on rails and do not require drilling. Follow the included instructions for the exact truck application.

What is an Undercover SwingCase?

SwingCase is a lockable bedside toolbox that swings outward for access. It is designed for a specific truck side and bed application.

Can I use a bed rack with an Undercover cover?

Compatibility depends on the cover rail profile and rack mounting system. Verify both manufacturer instructions before combining accessories.

How do I choose the right bed cover length?

Use the factory bed length for the exact truck model, not just the overall truck length. A five foot and six foot bed require different covers.

Will a tonneau cover help protect cargo from weather?

A correctly installed cover helps shield cargo from rain, dust and sun. Weather sealing varies by product design and installation.

Can I install an Undercover cover at home?

Most applications are designed for straightforward installation with common hand tools. Review the instructions and have a helper for larger hard covers.

Do Undercover covers fit trucks with a spray-in bedliner?

Many do, but bed rail shape and liner thickness can affect clamp fitment. Check the application notes before ordering.

Where can I get help with Undercover fitment?

Use the year, make, model and bed length filters, then contact Black Ops Auto Works for fitment support before ordering.
