Dee Zee HEX aluminum rails can help organize cargo and provide mounting options on compatible pickup beds. This selection includes truck-specific longitudinal side rails, a separate universal crossrail and a tonneau-track crossrail kit. These components serve different purposes; identify the truck and mounting arrangement before choosing a part.
What does the HEX rail attach to?
Run along the upper truck-bed sides and generally attach at specified stake-pocket positions.
Runs across a compatible cargo-rail structure. The universal DZ99781TB is not a longitudinal side-rail replacement.
The DZ99782TB is a separate mounting solution for approved tonneau-cover rail arrangements.
Dee Zee HEX rail MPN comparison
Manufacturer vehicle-specific installation sheets should decide whether a given stake-pocket rail fits the pickup's bed length and configuration.
| MPN | Part role | Installation style | Compatibility check |
|---|---|---|---|
| DZ99704TB | Bed-side rail pair | Stake-pocket mounting | Vehicle-specific mounting and bed length require exact application verification. |
| DZ99707TB | Bed-side rail pair | Stake-pocket mounting | Compare pickup model and stake-pocket positions with the manufacturer application. |
| DZ99708TB | Bed-side rail pair | Stake-pocket mounting | Do not substitute for DZ99704TB or DZ99707TB without a confirmed fitment match. |
| DZ99799TB | Bed-side rail | Stake-pocket mounting | Check whether sold singly or as a set on the current product listing. |
| DZ99781TB | Universal HEX crossrail | Mounting depends on approved HEX system | Check the compatible HEX rail system and mounting hardware. |
| DZ99782TB | Tonneau crossrail kit | For specified tonneau-track configuration | Do not assume compatibility with stake-pocket side rails or every tonneau cover. |
Fit, loading and installation
Measure the truck-bed rail layout and identify any tonneau cover, tool box or factory cargo-channel equipment that may affect installation. Follow the specific Dee Zee mounting instructions rather than assuming one rail kit fits every pickup.
Dee Zee lists a 200 lb capacity for DZ99781TB and DZ99799TB, but that figure must not be assigned to all models or combined with unrelated hardware ratings. The vehicle, attachment points and cargo restraint arrangement may impose lower limits.
Dee Zee's HEX stake-pocket rails listed here are not specified for integration with a truck-bed tool box. Do not use any rail for supporting loads or accessories outside its manufacturer's approved applications.
