Overview
The Bestop PowerBoard NX 75638-15 is a black retractable electric running board for 2011–2018 Ram 1500, 2500 and 3500 trucks. The boards stay under the body while the doors are closed and step down to meet your foot when a door opens, on the front and rear doors of either side.
This NX edition uses patent pending wireless controllers in place of the usual door-trigger wiring. The controllers signal the boards to retract and drop as the doors open and shut, with no connection to the factory wires. The design avoids conflicts with other aftermarket wiring, such as security systems and remote starts. It suits Ram owners who want a powered step without opening the door trim.
Key features
- Wireless door controllers, patent pending
- Boards retract and drop as each door closes and opens
- No connection to the factory door wiring
- Installation avoids door panels, kick panels, kick plates and carpet
- Compatible with aftermarket security systems and remote starts, per Bestop
- Black finish with a Cab length designation
Choosing a powered running board
A powered running board is a good fit for a Ram that is used for daily driving and occasional work. Higher cabs can be hard to reach, and a board that drops to a set height helps with boots, wet mornings and loads carried in the cab. Consider how often you climb in and out, and whether passengers, including children, will use the steps.
Look at the rest of the truck before you buy. Lift kits, larger tires and bed accessories change the ride height and the swing path of the board, so check clearance against the modifications you already run or plan to add. Mud, road salt and gravel can build up in the mechanism, so a board that is washed and checked regularly tends to last longer.
Wireless controls remove some installation work, but the boards still depend on sound mounts and clean connections. Recheck the mounting hardware after the first few drives, and keep an eye on the door sensors, which should trigger the step consistently.
- Consider cab height and daily entry needs
- Check clearance against lift kits and larger tires
