Product Description

The Rock Slide Engineering BD-SS-302-JT4D is the driver-side step slider for the latest 3rd Generation kit built specifically for the 2026 Jeep Gladiator JT, combining a trail-rated rock slider with a fully functional power step for easier truck-bed-height entry and exit. This revision brings cosmetic contour changes that let the step curve to follow the Gladiator's body shape, minimizing the gap between the rear extension and the fender flare, along with 2 extra inches added to the back of the step for safer access to the rear door.

The slider uses Rock Slide's smart motor technology - with the gas strut removed from the step internals - to keep the step deploying and retracting consistently even in cold or harsh weather, while a built-in sleep mode helps minimize battery drain between uses. Built from 3/16 in. steel with stainless steel and aluminum internals, the unit is finished in a durable black, textured powder coat to stand up to daily off-road driving conditions, with the step automatically dropping 12 inches down from the body of the slider every time the door opens.

Installation is bolt-on directly to the truck's existing mounting points, taking roughly 3 hours for someone with light-to-moderate mechanical skill. This listing is for the driver-side unit only, as part of Rock Slide's complete 3-box BD-SS-302-JT4 kit; the passenger side and rear extension are sold as matching sub-parts. Owners can further outfit the setup with optional skid plates, rocker guards, an LED light kit, or a door delete kit, all sold separately.
