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

Cab-length board

The regular, extended and crew-cab groups have different intended running-board lengths. Confirm the vehicle's actual body style.

Board finish

These NXT boards use black powder-coated aluminum; DZ16322 adds chrome-plated trim to the crew-cab version.

Specific bracket kit

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.

NXT board identification numbers

MPN Cab-length group Board material / finish
DZ16301 Regular-cab length Black aluminum
DZ16311 Extended-cab length Black aluminum
DZ16321 Crew-cab length Black aluminum
DZ16322 Crew-cab length Black aluminum, chrome trim

NXT mounting bracket identification

This comparison identifies bracket families, not confirmed pairings between every listed board and bracket.

MPN Vehicle application reference Mounting arrangement
DZ16315 Selected Silverado/Sierra Rocker-panel bracket kit
DZ16319 Selected Colorado/Canyon crew cab Rocker-panel bracket kit
DZ16325 Selected Ford F-150 Rocker-panel bracket kit
DZ16326 Selected Ford Super Duty Rocker-panel bracket kit
DZ16365 Selected Toyota Tundra Rocker-panel bracket kit

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 no-drill bracket still requires a vehicle match

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.

Find the original NXT board or bracket

Open a part-number listing to check its details and current availability.
