When identifying a Dee Zee NXT running-board setup, distinguish the aluminum step board from the rocker-panel brackets. The board's MPN tells you its cab-length group and finish; the mounting kit's MPN points to a specific vehicle application. The two pieces must be identified separately before replacing a missing or damaged part.
Separate the board from its mounting kit
The regular, extended and crew-cab groups have different intended running-board lengths. Confirm the vehicle's actual body style.
These NXT boards use black powder-coated aluminum; DZ16322 adds chrome-plated trim to the crew-cab version.
Rocker-panel hardware is sold separately. Check Dee Zee's application guide for the precise vehicle and board combination.
Do not assume similar brackets share a hole pattern.

Inspect the original mounting points
Record the board MPN and original bracket stampings if available. Verify truck year, cab style, rocker-panel holes and existing factory step equipment. Check corrosion or bending at every attachment point.
A bracket listed for F-150, Tundra, Silverado/Sierra or another vehicle does not automatically fit every NXT board or every year of that truck. Do not select an unverified board-and-bracket combination solely from this comparison.
