The Ram 2500 tri-fold tonneau cover

Tectonic™ is a solid aluminum folding bed cover for the Ram 2500 that combines patent-pending dual-motion access, weathertight sealing, key-locking security and haul-on-top strength, all in a cover that operates smoothly and easily.

Dual-Motion Access

The Ram 2500 Tectonic™ tri-fold bed cover pairs patent-pending dual-motion access with smooth, easy operation, so getting into your truck bed never gets in the way of the job.

Built To Haul On Top

Solid aluminum panels give your Ram 2500 a hard folding tonneau cover strong enough to carry cargo on top, not just keep it covered.

Weathertight And Secure

Sealed against the weather and locked with a key, the Tectonic™ Ram 2500 tri-fold bed cover protects what you haul.

Which Tectonic™ is right for me?

Sport, Pro, and Max all share the core architecture that makes Tectonic™ the platform it is. Our patent-pending dual-motion design lets you fill the bed to the brim and keep everything within reach.

Every Tectonic™ is a secure, weather-sealed fortress with no-limits access and haul-on-top capability.

Each edition builds on that foundation differently, so you can pick the tier that matches how hard you run your truck. Whichever you choose, it shows up factory-direct and ready to rock.

A capable workhorse at a solid value. Dual-motion access, robust security and all-weather-ready. Everything that makes a Tectonic a Tectonic.

Solid & Smart

All the strength without the limits

All the strength without the limits

1. The roof over your bed

Our panels are crafted from laser welded 5052-H32 solid aluminum, with 50% greater tensile strength than 3003 alloy aluminum.

2. These are no cheap hinges

Hinges machined from 6061-T6 Aircraft Grade Aluminum with Type III UV Resistant Anodizing (architectural grade). In other words, ready for all the weather, salt, and dust you can throw at it.

3. Built to carry

Machined aluminum and architectural anodized tie-down cleats are integrated directly with the structural support stud underneath, ensuring your cargo on top isn't going anywhere.

4. Layers of protection

Your cargo is sealed from the elements by multiple layers of protection, including a full perimeter gasket, secondary rail seal and internal rain gutters at the hinge points.

5. Welded Support Beams

5052-H32 aluminum welded structural support beams provide weight distribution and increased strength.

6. Twice the Finish of other Covers*

Literally. First we powdercoat the entire cover with an underbody automotive grade powder to provide incredible adhesion and tooth for the final coat. Then we throw down an indestructible spray-on bedliner finish ready for anything you can throw at it. *Tectonic™ Max only.
