The Multi-Flex Dilemma: Which Hard Folding Covers Work with Chevy’s Fancy Tailgate?

You just bought a brand-new 2024 Silverado 1500 High Country equipped with the highly sought-after Multi-Flex Tailgate.

It’s an absolute game-changer for truck utility. It instantly turns into a bed step, a standing desk, and a load stop for long lumber.

Now, you naturally want to add a secure, flush-mounted Hard Folding Tonneau Cover like the legendary BAKFlip MX4 to keep your gear safe.

But you’ve been on the forums, and you’ve heard the expensive horror stories:

"I dropped my Multi-Flex inner gate, and it smashed right into the aluminum rail of my bed cover!"

It’s completely true. The swing geometry of the 6-way folding tailgate is incredibly tight.

If the aftermarket bed cover rails stick out even half an inch too far, or the rear rubber weather seal is too thick, the tailgate step will violently hit them when you try to drop it down.

The great news is that premium manufacturers have engineered a fix.

Newer, updated revisions of the BAKFlip MX4 and UnderCover Ultra Flex feature explicit "Multi-Flex Compatible" rear rails that are trimmed back to allow 100% full clearance.

In this guide, we list the specific part numbers that play nice with your advanced tailgate, and warn you about the older, incompatible models you need to avoid.

Frequently Asked Questions (Hard Folding Covers)

Can I drive on the highway with the cover folded all the way up against the cab?

Yes, absolutely.

Premium hard folding covers (like the BAKFlip MX4 and UnderCover ArmorFlex) come equipped with heavy-duty strut "Prop Rods." You can fold the cover entirely up, lock it securely in place with the rods, and drive safely at highway speeds. This gives you full, unrestricted use of your truck bed for hauling dirt bikes or furniture without ever having to unscrew and remove the cover.

Does the CarbonPro bed really need a special cover?

Yes, it requires specific mounting hardware.

The composite CarbonPro bed does not have a traditional metal lip for standard aluminum C-clamps to grab onto. If you buy a standard Silverado cover, the clamps will slip off under tension. You must buy a cover that includes the CarbonPro Adapter Kit, which utilizes special brackets that bolt directly and securely into the factory tie-down points inside the bed.

Will my Multi-Flex Tailgate hit the rear rail of the cover?

Not if you buy the updated, compatible versions.

Early generations of hard folding covers severely interfered with the Multi-Flex "inner gate" step. However, the current generations of the BAKFlip MX4 and UnderCover series have been precision-updated with slightly shorter side rails and revised rear seals to completely clear the tailgate swing path. Always verify the fitment notes before checking out.
