You Upgraded Your Grand Cherokee. Now Cab Entry is an Obstacle.

You built or leveled your WK2 Grand Cherokee for enhanced presence, daily comfort, and premium capability. What you didn't plan for was the daily physical strain of climbing into the driver or passenger seat. Fixed stationary steps look like a bulky aftermarket afterthought, permanently compromise your true breakover angle, and track mud right onto your pant legs during entry.

Worse yet, standard step options are fundamentally vulnerable to real-world elements. In the freezing salt and slush of the Corrosion Belt, road brine migrates into unshielded pivot pins, causing electric step linkages to seize, pit, and fail when your family is running errands in January. In high-heat arid regions, punishing UV rays turn cheap composite steps chalky and brittle within a single season. Every time your door swings open, you depend on a linkage that is actively being degraded by the climate.

The AMP Research PowerStep (SKU: 76334-01A) is the definitive engineered solution. Purpose-built exclusively for the 2018–2019 Jeep Grand Cherokee WK2 platform, this system features smart, high-torque electric motors that automatically deploy a rugged, full-length step surface down the moment a door opens. When the doors close, the steps retract completely flush beneath the rocker panels—preserving your clean factory body lines, optimizing aerodynamics, and delivering an effortless step-in height.

The Obsidian Take

We carry the AMP Research PowerStep for the 2018–2019 Grand Cherokee because it bridges the gap between premium luxury aesthetics and commercial-grade durability. Most generic e-commerce listings use lazy automated text claiming their steps universal-fit anything from sports cars to trucks with options for "Dana 30 or Dana 44 flip kits." That is sloppy, inaccurate data filler. The 76334-01A is an ultra-specific mid-size unibody SUV kit, geometrically mapped to match the exact rocker panel welds and sub-frame mounting holes unique to the WK2 generation.

Instead of flimsy stamped metal, the steps are built from high-tensile die-cast aluminum coated in a military-grade anodized and PTFE non-stick corrosion shield. Whether you are navigating slushy northern winter roads or blistering desert heat, this finish prevents oxidation and ensures the non-slip traction surface stays perfectly intact. Driven by weather-sealed, high-torque electric motors and complemented by integrated OEM-style LED courtesy lights, it delivers silent, premium operation that matches the elite refinement of your Jeep.

⚠️ WK2 Generation Geometry Only: This kit is mathematically and physically tailored exclusively for the 2018–2019 WK2 platform. It will NOT fit 2021–2026 Grand Cherokee (WL platform) models or the 3-row Grand Cherokee L, as the body stamps and door-trigger electronics were completely redesigned for the newer generation.

⚠️ Model Year Electronics Fact: The provided manufacturer data sheet isolates this SKU strictly to the 2018–2019 range. Due to generational updates in Jeep’s digital internal gateway modules and door-trigger communication networks, the 76334-01A harness interfaces perfectly only with these production years. Attempting to force-install this on an older 2011–2016 WK2 will result in CAN-bus communication faults.

⚠️ Rocker Mount Obstructions: This system requires a clean, unobstructed factory rocker panel path to complete its outward and downward sweeping travel arc. It is NOT compatible with vehicles equipped with aftermarket frame-mounted rock sliders or extended custom lower body molding.

Confirmed Fitment Matrix

CRITICAL FITMENT NOTE: This kit is engineered strictly for the 2-row unibody WK2 Jeep Grand Cherokee platform for the specified model years.

❌ This Unit Does NOT Fit:

• 2021–2026 Jeep Grand Cherokee (WL Platform): Next-generation unibody layout and pinning networks do not align.

• Jeep Grand Cherokee L: Extended 3-row wheelbase models utilize an entirely different rocker panel profile.

• 2011–2017 Jeep Grand Cherokee: Older electronic bus modules do not accept this plug-and-play wiring configuration.

• Jeep Cherokee (KL) / Wrangler (JK/JL): Completely different vehicle platforms; entirely incompatible.

Technical Specifications

Before You Order — 4 Fitment Checkpoints

Electronic running boards require precise platform validation before processing. Review these four checkpoints prior to checkout:

1. Generation Validation: Confirm your Grand Cherokee is a true 2018 or 2019 WK2 platform. If your vehicle is a newer generation 2021+ model, do not buy this kit—it will not mount to your chassis.

2. Body Configuration: Verify your Jeep is the standard 2-row version. If you have a 3-row version with the "L" emblem, your rocker lengths differ and this kit will be too short.

3. Underside Rocker Guard Check: Ensure your vehicle's lower sills are free of aftermarket steel rock sliders, step bars, or custom lower body styling kits that could collide with the step's sweeping deployment path.

4. No Wire Splicing Rule: Review your installation setup. Never use cheap T-taps or scotchlocks on the digital door-trigger lines, as cabin vibrations will introduce signal flicker and permanent fault codes.

Professional Installation & Mechanical Notes

• Harness Before Hardware: Pro Tip: Always route your primary electronic harness and plug into the factory door-trigger ports before lifting and bolting the 54 lb aluminum step rails to the underbody mounts. It is substantially simpler to manipulate wires while the underside is wide open.

• Squaring the Hardware: Cycle the step motors electronically by triggering the door switches prior to applying final torque values to the linkage fasteners. This permits the components to align naturally and prevents premature motor bind.

• Dry Silicone Maintenance: While the premium PTFE finish keeps road salt and grime from sticking, spray the primary pivot pins periodically with a high-quality dry silicone lubricant to keep the high-torque motors moving silently through winter tracking conditions.

AMP RESEARCH POLICY NOTE: Due to the vehicle-specific programming integrated into the plug-and-play electronics box, once the wiring harness has been connected to vehicle power, this system cannot be returned. Verify all configuration metrics prior to unboxing.

Questions We Get Asked

Why does this kit only list the 2018 and 2019 model years for the Grand Cherokee? Jeep implemented specific mid-generation revisions to the WK2’s internal electronic gateway modules and body wiring harnesses. AMP Research engineered the plug-and-play harness in the 76334-01A kit to match the exact digital pinning configuration unique to the 2018–2019 production lines.

Does this kit require cutting or splicing into my Jeep's factory wiring? No. This system features a true plug-and-play wiring network that interfaces cleanly with the vehicle's factory door-trigger circuits, ensuring your factory Jeep vehicle warranty remains fully intact.

Can I run this kit if my Grand Cherokee has an aftermarket leveling kit? Yes. This kit is completely compatible with stock-height, leveled, or suspension-lifted Grand Cherokees. It drops down to provide a comfortable entry point regardless of your ride height configuration.

Are the LED entry lights included with this part number? Yes. Low-profile LED courtesy lights are completely integrated into the 76334-01A kit. They mount discreetly to the linkages and illuminate the step surface and ground automatically whenever a door opens.
