Factory replacement motor cover engineered to restore reliable retraction and shield drive components on AMP Research CRH PowerStep running boards.

Made to exact OE specifications for AMP Research part number 19-03289-90, this precision-molded housing restores clean lines while sealing the internal deployment motor against dirt, moisture, and roadside impact. Constructed with impact-resistant materials that mate directly with standard die-cast aluminum frames and stainless steel pivot pins, it eliminates wobble and returns smooth, silent operation to your retractable steps.

• Complete Model Compatibility: Specifically engineered for AMP Research Original and CRH PowerStep assemblies, aligning precisely with factory mounting brackets and door-activated trigger switches.
• Exact Dimensions: Measuring 7.5 inches long, 5 inches wide, and 2 inches tall at just 1.9 pounds, it maintains the original center of gravity without overloading the extension mechanism.
• All-Weather Component Protection: Tightly sealed housing routes water away from electrical contacts and bearing shafts, preventing corrosion during heavy rain, snowmelt, or off-road splashing.
• Direct Replacement Fit: Aligns flush with existing chassis channels, allowing straightforward swap-in using supplied fasteners without cutting, welding, or specialty tools.
• Structural Durability: High-density construction withstands constant thermal expansion, UV exposure, and high-frequency deployment cycles, matching the operational lifespan of the core aluminum body.
• Restored Factory Appearance: Contours match the original side-step silhouette, erasing cracks, fading, or stripped threads that compromise aerodynamics and ground clearance perception.

When cracked shrouds allow grit into the drive gear or expose wiring fraying under vibration, automatic extension timing becomes inconsistent or fails entirely. Installing this genuine AMP Research repair component seals the critical transition zone between the vehicle body and the moving step plate. This single-part upgrade preserves the original electrical routing, prevents premature hinge wear, and keeps your entry system functioning reliably across all seasons.
