Go Rhino 20405187PC E1 Electric Running Boards 15-19 Silverado Sierra 2500 3500

Vehicle Fitment

• 2015-2019 Chevrolet Silverado 2500HD (Crew Cab, Diesel Engine Only)
• 2015-2019 Chevrolet Silverado 3500HD (Crew Cab, Diesel Engine Only)
• 2015-2019 GMC Sierra 2500HD (Crew Cab, Diesel Engine Only)
• 2015-2019 GMC Sierra 3500HD (Crew Cab, Diesel Engine Only)

Fitment Notes

• This specific kit is for Diesel engine models only - the bracket geometry differs between diesel and gasoline configurations on the 2015-2019 2500/3500HD platform. Gasoline models require a different part number.
• Fits Crew Cab (4 full-size doors) configuration only. Double Cab and Regular Cab applications require different part numbers.
• No drilling required for installation - this kit mounts using factory attachment points.
• Does not affect or require use of the OBD-II diagnostic port - the magnetically-activated door switch system bypasses the OBD port entirely.

Features

• Automatic electric deployment and retraction triggered by opening and closing the vehicle doors - the step extends when any door opens and fully retracts when all doors are closed, providing optimal ground clearance and rocker panel protection when not in use.
• Dual electric motors on each running board - four motors total for the pair - ensure reliable, consistent operation in extreme temperatures and all-weather conditions including rain, snow, mud, and ice.
• 6-inch wide aluminum step surface with raised ribbed anti-slip treading provides a secure, full-length stepping area across the cab length of the vehicle.
• Integrated LED lights automatically illuminate the running board when deployed, enhancing visibility and step safety in low-light and nighttime conditions.
• Magnetically-activated door switches use a sensor-based activation system that requires no physical connection to the OBD-II port, keeping the diagnostics port free for tuners, monitors, and other accessories.
• Automatic SAFE-STOP detection engages immediately if an object or obstruction is detected in the board's deployment path, preventing damage and injury.
• Interior bypass switch allows manual override of the automatic deployment system - enabling the boards to be locked in the retracted position when desired.
• Textured black powder coat finish provides corrosion, impact, and abrasion resistance and is backed by a 5-year finish warranty.
• Rated for up to 600 lbs per side - providing ample support for entry and exit on a full crew cab truck.
• No-drill installation uses factory bracket mounting points - no modification to the vehicle body is required.

Product Description

The Go Rhino 20405187PC E1 Electric Running Board Kit is a complete, vehicle-specific retractable step system engineered for the 2015-2019 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD in Crew Cab configuration with diesel engines. When any door is opened, the dual-motor system instantly deploys both running boards to a secure, 6-inch-wide aluminum stepping surface with raised ribbed anti-slip treading - providing confident, stable entry and exit access for drivers and passengers. When the doors are closed, the boards retract fully against the rocker panel, preserving the truck's profile, protecting the rocker panel from road debris, and maintaining maximum ground clearance for off-road and work-site use. The textured black powder coat finish integrates cleanly with the dark trim and body lines common to these heavy-duty platforms.

The E1's dual-motor-per-board design - four motors total across both sides - is Go Rhino's engineering answer to the reliability demands of all-weather use on heavy-duty trucks. The system is designed to operate consistently in extreme cold, rain, snow, and mud, where single-motor systems used by competitors can be more susceptible to failure. Door activation is handled by magnetically-activated switches that sense door position without any connection to the OBD-II diagnostic port - a practical distinction for truck owners who use handheld tuners, performance monitors, or fleet diagnostic tools. Integrated LED lights automatically illuminate the step surface when the boards deploy, providing added visibility at night and in poorly lit loading dock, job site, or off-road environments. The automatic SAFE-STOP system monitors the boards' deployment path and halts movement if an obstruction is detected, while an interior bypass switch allows manual control when hands-free operation is not desired.

This kit is calibrated for diesel engine models only - the bracket geometry on the 2015-2019 2500/3500HD platform differs between diesel and gasoline configurations, and the incorrect kit will not mount correctly. Confirm your engine type before ordering. The complete kit includes both running boards, the vehicle-specific dual-motor bracket system, wiring harness, LED light kit, door switches, interior override switch, all necessary mounting hardware, and an installation guide. Installation requires no drilling and uses factory attachment points. Go Rhino backs the E1 with a Limited Lifetime warranty on materials and construction, and a 5-year warranty on the textured black powder coat finish.
