You Lifted Your Ram Truck. Now Your Cab Entry Is a Climb.

You put a premium lift kit and massive tires under your Ram truck to maximize its ground clearance, stance, and off-road capability. What you didn't plan for was the daily strain of getting into the cab. Fixed running boards ruin your ground clearance and look bulky, while cheap electric steps lag, flex under load, and leave your truck looking like an unpolished afterthought.

Worse yet, standard single-motor steps easily fail when faced with real-world punishment. High-humidity coastal environments pit raw hardware, road brine seizes low-grade linkages, and consistent 100°F+ arid summer days warp under-powered electric motors. Every time you open your door, you are relying on a component that fights environmental variables instead of conquering them.

The AMP Research PowerStep Xtreme (SKU: 78239-01A) is the ultimate industrial-grade fix. Engineered specifically for the 2018–2026 Ram 1500, 2500, and 3500 platforms, this system features dual independent high-torque motors per side to drive a massive, rock-solid automatic steps package. It drops instantly when the door opens and tucks completely out of sight against the rocker panel when closed, preserving your true ground clearance while handling the absolute harshest climates on earth.

The Obsidian Take

We carry the AMP Research PowerStep Xtreme because it solves the inherent weaknesses of traditional electronic steps through superior mechanical redundancy. Most automatic steps utilize a single motor that relies on a slave linkage to pull the board up; if ice, mud, or road grime jams that linkage, the system binds and burns out. The 78239-01A system employs dual independent high-torque motors on each side, ensuring uniform power distribution across the entire linkage assembly.

Instead of basic raw aluminum or low-grade stamped steel, these steps are crafted from die-cast aluminum that is deeply anodized and heavily shielded with a military-grade PTFE corrosion-resistant coating. Whether you are dealing with winter liquid salt in the Northeast or blistering desert heat in the Southwest, this finish prevents pitting, oxidation, and binding. Combined with integrated OEM-style LED courtesy lights and a true plug-and-play wiring layout, it delivers a flawless, factory-finished operation every single time.

⚠️ Aggressive Offset & Tire Clearance Warning: While this kit is fully compatible with 2" to 6" suspension lifts, trucks running aggressive negative wheel offsets (minus 25mm or lower) or tires wider than 12.5" (35" or 37" diameters) must manually verify front tire clearance against the step's forward linkage arms during full lock-to-lock steering sweeps.

⚠️ Rocker Panel Slider Interference: This kit utilizes factory rocker panel mounting locations. It is NOT compatible with aftermarket frame-mounted rock sliders, body-mounted step bars, or extended custom rocker flares that extend into the step's downward deployment travel arc.

⚠️ Ram Generation Platform Fact: The provided documentation references a universal fit across all Ram trucks. Mechanically, the 78239-01A plug-and-play wiring harness is pinned specifically to interface with 2018–2026 electronic body control modules. Attempting to splice this harness into 2017 or older Ram architectures will result in immediate module communication errors.

Confirmed Fitment Matrix

CRITICAL FITMENT NOTE: This kit is engineered for specific cab and wiring configurations on the Ram truck platform. Verify your generation and body code before ordering.

❌ This Unit Does NOT Fit:

• 2017 or Older Ram Trucks: The digital door-trigger network and wiring pinouts do not align without custom harness retrofitting.

• Ram 3500 Cab & Chassis / Dually (DRW): Select rear dual-wheel fender flares or commercial utility boxes interfere with the rear linkage mounting paths.

• Pre-2018 Classic Models: Ensure your vehicle registration explicitly confirms production year validity.

Technical Specifications

Before You Order — 4 Fitment Checkpoints

Electronic steps require precise body and wiring matching. Review these four checkpoints prior to checking out:

1. Cab Configuration Matching: Verify that your exact cab style (Crew Cab, Mega Cab, or Quad Cab) correlates precisely with part number 78239-01A. Length parameters differ across configurations.

2. Body Styling Code: For 1500 owners, confirm whether your truck is the new body style (DT platform) or the 1500 Classic (DS platform). This kit accommodates both for the 2018+ year range, but harness paths vary slightly.

3. Rocker Clearances: Ensure your truck’s underside is free of aftermarket rock sliders, steps, or custom lower body molding that could block the board's outward swinging travel path.

4. Wheel & Offset Review: If you are running deep-dish off-road wheels with aggressive negative offsets, double-check that your front tires won't rub the front linkage when turning.

Professional Installation & Mechanical Notes

• Harness Routing Strategy: Pro Tip: Always route and connect the Plug-N-Play wiring harness through the factory cab seals before lifting and bolting the heavy mechanical step brackets to the rocker panels. It is significantly faster to position the electrical lines while the underbody is clear.

• Pre-Torque Operational Test: Cycle the step motors electronically by tripping the door sensors prior to applying final torque loads to the mounting hardware. This ensures the linkage arms are perfectly squared up and prevents binding.

• Lubrication Maintenance: While the PTFE coating shields the metal links from corrosion, spray the pivot points periodically with a high-quality dry silicone lube to keep the dual-motor action cycling silently through heavy mud and winter road salt.

AMP RESEARCH POLICY NOTE: Due to the vehicle-specific programming and nature of electronic plug-and-play wiring harnesses, once this system has been connected to vehicle power, it cannot be returned. Double-check all fitment metrics before opening electrical components.

Questions We Get Asked

What makes the "Xtreme" version different from a standard AMP PowerStep? The standard PowerStep utilizes a single electric motor per side to deploy the board. The PowerStep Xtreme is engineered for extreme climates and sub-zero or high-heat environments, implementing dual high-torque motors on each side (one per linkage arm) along with a thicker sub-structure and premium PTFE finish to ensure it never binds in snow, ice, or thick mud.

Do I have to splice or cut into my factory Ram wiring harness to install this? No. This kit features a completely integrated Plug-N-Play pass-through OBD-II port harness. It plugs cleanly into your factory diagnostic port or door trigger lines to read the door-open signals digitally, eliminating wire splicing or voiding your factory truck warranty.

Will this kit work if my Ram 2500 has a 6-inch suspension lift? Yes, it integrates perfectly with lifted setups. However, if your truck is running an aggressive lift paired with oversized tires and deep negative offset wheels, contact us prior to ordering so we can confirm your tire clearance against the forward deployment linkage.

Are the LED step lights included, or do I have to buy them separately? The low-profile LED courtesy lights are completely included inside the 78239-01A package. They wire directly into the main AMP controller box and illuminate automatically when the steps deploy to safely light up the ground below the cab.
