Dee Zee HEX Truck Bed Rails: Side Rails vs Crossrails

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?

Longitudinal side rails

Run along the upper truck-bed sides and generally attach at specified stake-pocket positions.

Crossrail

Runs across a compatible cargo-rail structure. The universal DZ99781TB is not a longitudinal side-rail replacement.

Tonneau-track crossrail

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.

Cargo ratings apply to the exact component and installation

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.
