Common Questions
Why does my 2024 or 2025 Gladiator need a different SKU than the 2020–2023?
Jeep made changes to the Gladiator JT mounting geometry for the 2024 model year. The step slider mounting points changed, requiring a new SKU. Installing a 2020–2023 SKU on a 2024–2025 JT will result in a fitment mismatch. The 2026 JT again uses a different SKU (BD-SS-302-JT4).
What is the sleep mode and why does it matter?
The Gen III step slider includes a built-in sleep mode that reduces power draw when the step is not actively deploying or retracting. This minimizes battery drainage during extended periods of non-use — relevant for JT owners who leave the vehicle parked for extended periods without the engine running.
Does this void the Gladiator factory warranty?
The standalone plug-and-play wire harness requires no splicing or modification to factory wiring. Rock Slide Engineering states this design is intended to allow customers to retain their manufacturer warranty. Verify with your dealer before installation.
This is a sub-part — what else do I need?
The BD-SS-301-JT4E is the rear extension passenger side sub-part only. The complete system (BD-SS-301-JT4) includes both driver and passenger side step sliders, standalone wire harness, and magnetic door sensors. Order this sub-part only as a replacement for a damaged rear extension or if you already have the complete system.
The Obsidian Take
The BD-SS-301-JT4E is for the 2024–2025 Gladiator JT owner who needs a replacement passenger side rear extension for the Gen III Step Slider system — or who is building the system component by component. Same smart motor, same 12-inch auto-deploy, same plug-and-play installation as the 2020–2023 system, updated for 2024–2025 JT mounting geometry with the added sleep mode for battery management.
Confirm your model year before ordering. 2020–2023 JT needs BD-SS-300-JT4E. 2024–2025 JT needs this SKU. 2026 JT needs BD-SS-302-JT4 sub-part. One wrong year SKU on a non-returnable electrical product is a hard problem to solve.
