GMC Sierra K2XX LED Door Sills: 2014–2018 Choices

GMC Sierra K2XX · 2014–2018

Choose Sierra or DENALI lettering for a stainless-steel entry accent, then match the set to your actual cab and doorway.

Start with K2XX, not the badge alone

The two products below are intended for GMC Sierra K2XX, 2014–2018. Choose within that vehicle range before comparing the lettering. A Sierra or DENALI wordmark does not establish the cab configuration, door count or shape of the mounting surface.

Confirm your model year, cab style and intended front or rear door positions with the team before ordering. This guide does not extend the range to 2019 or later trucks or claim that every K2XX cab uses the same plate dimensions.

Two designs, one material choice

Two Sierra-logo Stainless door sill plates with white lettering, fine top bars and edge illumination
Sierra lettering. The vehicle name and two fine light bars create a simple horizontal design. View the Sierra-logo product.
Two reflective DENALI-logo Stainless door sill plates on a white background
DENALI lettering. Choose this artwork for the name you want to display. The lettering alone is not a cab-fitment guide. View the DENALI-logo product.

Both are Stainless products. The optional Black Raptor finish is a black protective coating over the same stainless-steel construction; it does not turn the set into Matte PRO. Choose the surface separately from the artwork.

Decide how much light you want to see

These Stainless designs illuminate through the lettering, top bars and side edge. White keeps the artwork easy to read against the metal. A static colour gives the doorway a consistent accent; Flow RGB is the smartphone-controlled option. Select from the colours currently offered on the exact product page.

The product photos show the plate design, not a measured fit for every cab. Front and Front+Rear are separate set choices. Match the supplied set to the door positions you intend to equip rather than assuming that a photo of two plates represents all possible positions.

Check the mounting area before fitting

The adhesive-backed plates mount on prepared, flat painted metal. Remove the stock plastic cover from the intended mounting area and dry-position the plates before securing them. The inner edge should meet the rubber seal without a visible spacer or overlap onto rubber.

These are wired accessories, not battery-powered replacements. The listed red positive and black negative leads connect to a suitable vehicle source; a door-activated circuit lets the light follow door opening. Route wiring beneath the trim and confirm the connection with the installer before fixing the plates down.

Build a specific order

Send the year, cab style, selected product link, desired artwork, colour and Front or Front+Rear choice. Ask the team to confirm the mounting dimensions for that vehicle. Choose Sierra lettering, choose DENALI lettering, or check your cab and set before ordering.
