Dee Zee's HEX rail family includes several distinct items: longitudinal bed-side rails, a universal crossrail and a crossrail kit intended for compatible tonneau rails. Before replacing a damaged component, identify the MPN and the original mounting system. Similar black hexagonal profiles do not prove interchangeability.
Identify the installed rail type
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.
Match the exact HEX part number
Use the model number and original mounting location to distinguish a side rail from a crossmember.
| 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. |
Check the original mounting and hardware
Inspect stake-pocket positions, original fasteners and rail condition. Check whether the damaged piece was a side rail, crossrail or tonneau-track kit, and confirm the correct part for the truck's year and bed length.
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.
