Step By Step Install

At a glance

Overall sentiment is overwhelmingly positive: reviewers say SharpTruck finishing caps/mud flap delete kits fit well, install easily (often without cutting/drilling), look OEM, and help improve tire clearance and aesthetics; a minority report imperfect alignment/gaps, continued rubbing for some tire setups, and concerns about price and paint/material durability.

What Customers Liked

  • Frequently described as “fits perfectly/like a glove/factory piece,” matches fender flare lines and texture, cleans up wheel-well/fender lines, and looks far better than stock mud flaps/splash guards.
  • Quick install (often 15–60 minutes for all pieces) with simple hand tools; many installed without removing tires; instructions and install videos praised; uses factory mounting points/hardware in many cases.
  • Major selling point versus competitors: typically no drilling, no additional holes, and no cutting into the truck’s metal; avoids “hacking” factory guards.
  • Many report reduced or eliminated rubbing after leveling/lift and larger tires (commonly 35–37"), improved clearance at full lock, and better compatibility with aftermarket wheel/tire setups (some still needed minor trimming).
  • Often called heavy-duty/solid, better than expected or better than OEM, good fit-and-finish; texture/black trim match noted; packaging praised (individually wrapped).
  • Fast shipping (often within days/under a week), good packaging, responsive support, and occasional handwritten thank-you noted.
  • Viewed as a “must-have” when installing aftermarket mud flaps (e.g., Gatorback) and for deleting factory splash guards cleanly.

Things to Consider

  • Some report gaps, misalignment (especially fronts or rears on certain trucks), holes not lining up exactly, or needing adjustment; occasional suggestion that front pieces could be improved.
  • Not a guaranteed fix for every wheel/tire/lift combination; some users still experienced rubbing on full lock or needed additional trimming despite installing the caps.
  • Multiple mentions that parts are white/clear plastic with a black textured coating/paint; scuffs/chips can reveal white underneath; some wish they were molded in black or painted inside edges/seams.
  • Common complaint that they’re pricey/overpriced for plastic; some compare favorably to more expensive brands but still feel cost is high.
  • A few notes about needing extra bolts/screws for certain factory configurations, tricky access on rear flaps, difficult clips/tabs to remove without breaking, and one report of long-term hardware/locking nut failure/corrosion after reuse.
  • Some wish kits included all 6 locations by default or that additional caps (e.g., in front of rear wheels) were included/available in smaller pairs; some ordered the wrong kit size and needed more pieces.
  • A few users noted the match is close but not perfect on close inspection or not an exact color match to their trim.

Finishing caps gave my truck the final touch it needed

I decided to order these finishing caps from Sharp Truck after watching the installation videos. I didn’t want anything I had to make additional holes in the vehicle and these came with easy install instructions. The material they are made out of is excellent quality, better than I had expected! These caps gave my truck the final touch it needed. I’m extremely impressed with quality and not mention the fact I received them in less than a week after placing the order. I highly recommend this product.

Fit like a glove. Zero drilling or cutting like the other cheaper brands. Installed in a little over an hour and couldn’t be happier.

Hello, I recently purchased the 2019 Sierra, 4 piece mud flap delete but I am going to need the rear ones. I looked on your page and it looks like I need to purchase all 6. Can you just sell me the rear mudflat deletes for a 2019 Sierra? Much appreciated

Here is the pair that goes in front of the rear tire,

I assume these fit new body style GMC Sierra 2500 as well?

- Rob on 3/17/2022

No, these only work on the 1500. Gatorback is working on caps for the Sierra HD but they are not complete yet.

- Admin on 3/17/2022

Will these fit the refreshed 2023 AT4x sierra 1500 with no drilling?

- Scott on 1/30/2023

Yes
