AMP Research PowerStep XL | 2019-2026 Ram 2500/3500 Mega Cab Plug-N-Play

The Obsidian Vision

The AMP Research PowerStep XL was engineered for one purpose: to make a lifted Ram 2500 or 3500 Mega Cab accessible without sacrificing an inch of ground clearance or visual aggression. The XL's extended-drop step surface deploys wide and low on door open, then retracts flush to the rocker panel on door close — leaving a clean, uninterrupted body line that looks factory and performs beyond it. This is the running board for the build that doesn't cut corners.

Concierge Fitment Guarantee

Every order is manually reviewed by our technicians to ensure 100% compatibility with your build before we ship.

Engineering Breakdown

• Eliminates dangerous entry height on lifted Ram 2500/3500 Mega Cab builds with an extended-drop step surface engineered specifically for tall suspension setups.
• Retracts flush to the rocker panel on door close, preserving maximum ground clearance and a clean OEM body profile with zero step drag risk.
• Increases long-term durability in harsh climates through a weather-sealed dual-motor drive system and PTFE-coated anodized die-cast aluminum construction.

The PowerStep XL's extended-drop geometry is the critical differentiator from the standard PowerStep — the XL's linkage arc is calibrated to deploy the step surface 2–3" lower than the base unit, directly addressing the entry gap created by 4–8" suspension lifts common on HD Ram platforms. The dual-motor weather-sealed system uses independent side actuation, so a single motor event does not disable the full system. Die-cast aluminum boards and linkages are anodized and PTFE-coated, creating a barrier against road salt, ice adhesion, and corrosion that outlasts powder coat finishes in sub-zero and high-humidity environments. Plug-N-Play wiring integrates directly with the OEM door-trigger harness — no relay kits, no splicing, no dealer programming.

Verified Fitment (OFAS Standard)

✅ CONFIRMED FITMENT:

• 2019–2026 Ram 2500 Mega Cab
• 2019–2026 Ram 3500 Mega Cab SRW

❌ FITMENT REQUIREMENTS:

• Ram 2500/3500 Crew Cab or Quad Cab: Requires the standard PowerStep or PowerStep Xtreme — the XL linkage geometry is calibrated exclusively for Mega Cab door/rocker dimensions.
• Ram 1500 (All Configurations): Requires a Ram 1500-specific PowerStep unit — platform architecture is not compatible with HD XL geometry.
• Aftermarket Rock Sliders / Extended Flares: Body clearance verification required before installation — confirm no interference with step travel arc.

Installation & Technical Notes

• Plug-N-Play wiring connects directly to OEM door-trigger harness — no relay kits or splicing required.
• Professional installation recommended for proper harness routing on Mega Cab configurations due to extended door sill length.
• Confirm cab configuration is Mega Cab — part number 77248-01A is not compatible with Crew Cab or Quad Cab rocker geometry.
• Keep hands and tools clear of step mechanism during automatic operation testing post-install.
• Once wiring is connected and unit is powered, the system is non-returnable per AMP Research policy.
• No alignment or suspension recalibration required for installation.

Wheel & Tire Fitment

The PowerStep XL is designed for lifted Ram 2500/3500 Mega Cab builds and is compatible with suspension lifts in the 4–8" range with standard HD wheel/tire packages. For builds running aggressive negative offsets (ET-25 or lower) or tires wider than 37", confirm step clearance with our team — wide-body flare kits and certain aftermarket slider/bumper combos may affect the step travel arc on the Mega Cab's extended rocker panel.

Our team is standing by to verify your specific cab configuration, lift height, and slider/flare setup. Purchase with confidence; we review every build.
