Nearly all quality Sierra boards are no-drill and clamp to factory mount points, though some tube steps still require drilling. Below are five ranked picks from powered premium to budget.

AMP Research PowerStep
Best for: Best powered retracting step
$1,300-$1,700
The PowerStep drops the moment a door opens and retracts flush under the rocker while driving. It is the premium way to add a step to a taller Sierra without giving up ground clearance.
N-FAB's round tube bars add a rugged step with drop-down pads at each door and a finish built to survive road salt. A go-to for Sierra work trucks that see all seasons.
The HDX hangs lower than the rocker so a lifted Sierra is far easier to step into. The wide serrated surface gives solid footing when the step is wet or muddy.
The iBoard gives the Sierra a wide flat aluminum step that runs the length of the cab for a finished, full-size platform. Great value for anyone who prefers a true board over a tube.
TAC delivers a functional tube step at the lowest price without feeling cheap. A smart pick for a Sierra owner who just wants a dependable step installed with hand tools.

🧭 How to Choose the Best Running Boards for Your GMC Sierra
Match your cab configuration
Regular Cab, Double Cab, and Crew Cab Sierras each take a different board length. Confirm your cab before ordering so the step pads sit under each door and the board does not hang past the ends or come up short.
Powered vs fixed vs drop-step
Powered boards retract for clearance and add the most convenience at a premium price. Fixed nerf bars and flat boards are simple and rugged. Wide drop-steps sit lower, which is best for a lifted Sierra or easier entry.
Install and materials
Most Sierra boards are no-drill and clamp to factory pockets in about an hour. Aluminum stays light and rust-free, while powder-coated steel is tougher for work use. Verify no-drill fitment before you buy.
❓ Frequently Asked Questions
How do I know which running boards fit my Sierra cab?
Determine whether you have a Regular Cab, Double Cab, or Crew Cab, then match the listing to that exact cab. Boards are cut to a set length so the pads land under each door, and a set for the wrong cab will not fit.
Are powered running boards worth it?
For a lifted or tall Sierra, or for passengers who find the climb hard, powered boards are worth it since they retract to keep full ground clearance. If clearance is not an issue, a fixed board or nerf bar does the same job for much less.
Do running boards require drilling?
Most Sierra running boards and nerf bars are no-drill and bolt to existing factory mount points. Some tube-style steps still require drilling, so check the description and confirm no-drill fitment first.
