Toyota truck and SUV platforms with RCI bed racks
The RCI Offroad Modular Bed Rack Tonneau Adapters unlock tonneau cover compatibility with RCI bed racks and bed bars on 3rd-gen Tacoma, 4Runner, Land Cruiser, and other Toyota truck platforms. These brackets bridge the gap between aftermarket tonneau covers and modular bed rack systems, letting you run a cover over your existing rack without sacrificing either component.
Tonneau Compatibility Without Compromise
Standard tonneau covers aren't designed to work with elevated bed racks. These adapters mount between your RCI rack and tonneau cover, raising the cover 3 inches to clear the rack legs and fastening points. This approach works with most roll-up and retractable covers that lack integrated T-slot rails.
- Four or Six Bracket Options: Kit quantity depends on your specific RCI bed rack or bar model—refer to fitment guide to confirm your bracket count.
- 3-Inch Elevation: Raises tonneau cover height above rack structure to prevent contact and binding during operation.
- Hard and Soft Cover Support: Compatible with roll-up covers, retractable covers, and certain tri- or quad-folding hard panel covers (note: folding panels will contact rack legs and prevent full opening on folding designs).
- Integrated Tie-Down Slots: Secures cargo on top of your cover without requiring additional aftermarket tie-down hardware.
- Optional Through-Bed Bolting: Holes allow bolting through the bed cap for added security, though most installations do not require this step.

Bolted right on and fit perfectly. Support even confirmed fitment before I ordered.
Finally a shop that actually knows Toyotas. No guesswork, no wrong parts.
Fast shipping and the install guide made it a one-evening job. Stoked.
