The GMC Sierra is GMC's flagship pickup, and our accessory range is designed to match its Professional Grade positioning. Shop LED door sills for extended and crew cab, Denali and AT4X badge upgrades, MultiPro tailgate trim and keychains sized for the 5th generation Sierra. Every piece is an aftermarket, compatible-fit product built to refresh the cab and bed without drilling.
The Sierra shares its bones with the Silverado but earns its price premium through details, and that is exactly where our accessories fit in - badge and trim upgrades that lean into the Professional Grade identity GMC has built around Denali and AT4X.
LED door sill plates are offered for both extended and crew cab configurations, protecting the entry step and lighting the way when loading gear at night. Stainless Denali or AT4X badge kits refresh grille and tailgate emblems, and separate MultiPro tailgate trim accessories dress up the 6-function tailgate itself.
Parts are sized for the 5th generation Sierra body (T1 platform, 2018+), covering the Duramax diesel and CarbonPro bed configurations, using 304 stainless steel and adhesive or factory clip mounting. These are aftermarket, compatible-fit accessories, not GM-issued parts.
Do sill kits differ between extended and crew cab? Yes, we offer separate kits sized for each cab length since the rear door dimensions differ.
Will AT4X badges fit a Sierra with the CarbonPro bed? Yes, badge placement is unrelated to bed material and fits any Sierra configuration.
Are running board steps compatible with the factory side steps? Most kits are designed to complement, not replace, factory-installed running boards; check your Sierra's factory equipment first.
