AMP Research PowerStep XL Running Boards
Our PowerStep XL running boards represent the ultimate solution for drivers of lifted trucks and full-size SUVs who demand maximum stepping surface and bulletproof durability. Engineered with an extra-wide platform, these boards extend 2 inches beyond our standard PowerStep model to provide confident footing even when your vehicle sits higher off the ground.
The XL platform deploys automatically when you open the door and retracts flush against the rocker panel when closed, preserving ground clearance and aerodynamics. We built these boards with an anodized aluminum construction that resists corrosion in salt, mud, and harsh weather while maintaining a premium appearance for years. Vehicle-specific brackets ensure a factory-quality fit with no drilling required on most applications.
Whether you're loading gear, helping passengers into the cabin, or accessing your roof rack, the PowerStep XL provides stable, slip-resistant footing exactly when you need it. Our sealed electric motor and linkage system operate reliably in temperatures from -40°F to 150°F, backed by our 5-year mechanical and 3-year finish warranty.
PowerStep XL Core Specifications
Construction and Materials
We machine the PowerStep XL platform from aerospace-grade aluminum alloy, then apply a multi-stage anodizing process that penetrates the metal surface to create a finish that won’t chip, peel, or fade. The material choice delivers serious weight savings compared to steel alternatives while providing superior corrosion resistance in coastal climates and winter salt zones.
Our engineers designed the linkage arms with aircraft-grade components and stainless hardware throughout. Every pivot point receives sealed ball bearings that eliminate the squeaks and play common in competitor designs. The electric motor sits inside a fully sealed housing with IP67-rated protection against water and dust intrusion, so you can pressure-wash your truck without worrying about internal damage.
Installation and Vehicle Compatibility
PowerStep XL running boards install with vehicle-specific mounting brackets that bolt directly to factory frame points on most truck and SUV models. We design each bracket set in CAD using 3D scans of actual vehicles, then validate the fit with physical prototypes before production. The result is a rock-solid mount that eliminates the shims and custom drilling required by universal-fit boards.
Installation typically requires 90 to 120 minutes with basic hand tools. Our kits include all necessary hardware, wiring harnesses with OEM-style connectors, and step-by-step instructions with photos. The electrical connection integrates with your door sensors through a plug-and-play harness — no wire splicing or electrical experience needed.
Operation and Performance
The PowerStep XL deploys in 0.8 seconds when you open any door, extending to the full down position before you step out. Door-mounted sensors trigger the motor the instant the latch releases, giving the board time to fully extend before your foot reaches the stepping surface. When you close the last door, the board waits 3 seconds before retracting to allow time for additional passengers.
Our sealed motor and gearbox generate enough torque to deploy the board even when ice accumulates on the linkage. The system draws less than 5 amps during operation and enters standby mode when retracted, consuming virtually no battery power. Built-in overload protection prevents motor damage if the board encounters an obstruction during deployment or retraction.

PowerStep XL Technical Questions
The PowerStep XL features a 7-inch-wide stepping surface compared to the 5-inch width of our standard PowerStep. This extra 2 inches of platform width provides more comfortable footing for lifted trucks and larger SUVs where passengers need to step higher to enter the vehicle.
Both models share the same motor, linkage design, and automatic deployment features. The XL uses heavier-duty mounting brackets to support the wider platform and increased weight capacity of 400 pounds per side.
PowerStep XL boards accommodate suspension lifts up to 6 inches on most truck models without requiring additional drop brackets. The wider platform extends far enough to provide good stepping height while maintaining adequate clearance underneath.
For lifts exceeding 6 inches, we recommend measuring from your rocker panel to the ground before ordering. If the distance exceeds 28 inches, you may need our Extreme Drop Kit to position the boards at a comfortable height. Our technical support team can help verify compatibility for your specific vehicle and lift configuration.
When fully retracted, PowerStep XL boards sit approximately 3 inches below your rocker panel, which typically results in minimal impact to your vehicle's original ground clearance. The boards position themselves tight against the body to avoid obstacles during off-road driving.
Most truck and SUV applications retain at least 8 to 10 inches of clearance from the bottom of the retracted board to the ground, though this varies by vehicle height and suspension setup. The low-profile retracted position preserves your approach and departure angles for trail driving.
Most customers with basic mechanical skills successfully install PowerStep XL boards in their driveway using common hand tools. The process typically takes 90 to 120 minutes and requires a socket set, torque wrench, and wire strippers.
Our vehicle-specific kits include detailed instructions with photos showing each step of the installation. The electrical connection uses plug-and-play harnesses on most applications, eliminating the need for wire splicing experience. If you prefer professional installation, our dealer network includes installers across North America who can complete the job in about 2 hours.
PowerStep XL boards include built-in overload protection that stops the motor if the board encounters resistance during movement. This prevents damage to the motor and linkage if ice, mud, or trail debris blocks the path.
The system automatically resets once you remove the obstruction. If the board detects repeated obstructions, the controller enters a diagnostic mode to prevent repeated cycling. You can manually reset the system by disconnecting the battery for 30 seconds, which clears the fault code and returns the board to normal operation.
The sealed motor and weather-resistant linkage operate reliably in temperatures down to -40°F. We design the system to break through light ice buildup during deployment, though heavy ice may require manual clearing before the board can move freely.
The stepping surface features drainage channels that shed snow and ice effectively. For best winter performance, spray the pivot points with silicone lubricant before freezing weather arrives. The anodized aluminum resists corrosion from road salt, and many customers in northern climates report years of winter use without finish degradation.
We maintain complete parts inventory for PowerStep XL boards including motors, sensors, controllers, linkage arms, and mounting brackets. All components are available for individual purchase with fast shipping directly from our facility.
Most repairs involve simple component swaps that customers can perform at home following our online guides. Common wear items like motor assemblies and door sensors typically cost less than professional labor would, making self-service repairs economical. Our technical support team provides free troubleshooting assistance to help identify the correct replacement part for your specific issue.
