Product Description

The Rock Slide Engineering BD-SS-300-JT4E is the 3rd Gen Step Slider End Section designed specifically for the 2020-2023 Jeep Gladiator JT. Sold as a pair, these end sections attach to the rear of the BD-SS-300-JT4 Step Sliders to add 2 inches of additional stepping platform at the back end - making rear door access significantly easier, especially on lifted Gladiators. The curved cosmetic profile follows the body line of the JT closely, minimizing the visible gap between the extension and the rear fender flare for a clean, factory-integrated appearance.

Built from 10-gauge HSLA laser-cut steel with stainless steel and aluminum internals, these end sections are engineered to the same trail-rated standard as the full step slider kit. The acid-etched, textured black powder-coat finish ensures long-term corrosion resistance under tough conditions. Installation is bolt-on using the supplied wiring harness and mounting hardware with no drilling required, and Rock Slide Engineering's Smart Motor technology keeps the step deploying and retracting reliably even in cold weather. Proudly made in the USA.
