Step by Step Instructions

At a glance

Reviews are overwhelmingly positive: customers say the step/running-board filler bars fit well, look OEM-clean, and install easily, with SharpTruck support and shipping often praised. Main negatives are price and occasional issues with bending/shipping damage, labeling, and material thickness/flimsiness.

What Customers Liked

  • Hides frame rails/tanks and the gap between cab and running boards; makes truck look cleaner, more finished, OEM-like; matches truck styling; embossed logo adds a dressed-up look; frequent compliments.
  • Standard size fits extended step boards; many reports of perfect/excellent fit across F250/F350/F450, F150, Bronco; looks like it belongs.
  • Install described as easy/straightforward; typically ~20–30 minutes (some ~1 hour); drilling aluminum appreciated by one reviewer; a bit tricky solo for some.
  • Often called high quality, well made, heavy gauge (especially stainless), nice design; packaging sometimes called outstanding.
  • Keeps road debris off top of running boards; helps prevent snow/ice/slush buildup on supports so doors don’t scrape or stick; added sense of safety in one review.
  • Fast shipping (2–3 days); SharpTruck responsive—quickly replaced damaged shipment; customers would buy again.
  • Black anodized chosen to hide dirt better than stainless; chrome/stainless also praised for flawless appearance.

Things to Consider

  • Repeatedly described as expensive/pricey for what they are; higher expectations at this cost.
  • Some say plates bend very easily, arrived slightly bent/with creases; one reviewer wanted thicker material due to bending if a foot slips; another called them flimsy and urged careful installation.
  • Reports of damage in transit (bent/creased), requiring straightening or replacement.
  • Driver/passenger sides not labeled correctly in one case (though easy to figure out).
  • One reviewer noted length is ~6 inches short vs the bars; another wanted them even with the step.
  • One buyer wanted black but didn’t see the option.
  • One installer had to drill extra holes and add screws due to OEM running-board fasteners (Ford) using fewer screws than expected.

Another customer, very satisfied and happy with new chrome running board for my favorite toy

Will they fit a crew cab

- JIM DOUGLAS on 12/9/2017

Yes, these are made to fit a crew cab.

Is there room for snow ect. To fall between step and fillers?

- Steve Harder on 12/29/2017

No there is not.  If there is a build up it would have to brushed off. But if paired with mud flaps there will be very little if any debris on the boards from driving.

Will these fit 2018 f350 crew cab factory 6" extended chrome running boards?

- Eric on 2/13/2018

The only wheel to wheel fillers available are part # G758504. These do not have the Super Duty logo stamped in them and fit on a truck with a 6'9" bed.

Prevent rocks, mud, snow and ice build-up on your steps. On some trucks with large gaps between the body and step, bar fillers also protect you and your passengers feet from slipping between this gap.
