Frequently Asked Questions
Will AVS hood shield 377185 fit my 2020-2023 GMC Sierra 2500 HD?
Match the complete year, make, model, hood, grille, trim, and every exclusion. A similar hood shape does not confirm fitment.
What profile and finish does AVS 377185 use?
The exact profile and finish are listed in the title and specifications. Confirm both before ordering because appearance and hood clearance vary by design.
Does AVS 377185 require drilling?
Installation method varies by exact application. Review the current AVS instructions and included hardware before drilling or applying adhesive.
What should I check after installing AVS 377185?
Verify hood opening and closing, latch operation, washer spray, wiper clearance, edge clearance, fastener security, and that the shield does not contact painted surfaces.
Installation Instructions
Follow the current AVS instructions for this exact part. Protect painted surfaces, test-fit the shield, confirm hood and grille clearances, install only the specified hardware or adhesive, tighten evenly without distorting the shield, then verify hood latch, wiper, washer, and panel operation.
AVS
Shop AVS window deflectors, hood shields, bug deflectors, light covers, and exterior accessories by exact manufacturer part number and verified vehicle fitment. Match the complete vehicle and product configuration before ordering because mounting position, body style, cab, door count, mirror arrangement, finish, and piece count can change compatibility.

In-channel and outside-mount versions attach differently and are not interchangeable merely because they appear similar. Hood Shields and Bug Deflectors Match hood protection to the complete vehicle, hood, grille, trim, profile, finish, mounting method, and every stated exclusion. Verify hood latch, washer, wiper, and painted-panel clearance after installation. How to Choose the Correct AVS Product Use the exact AVS manufacturer part nu...
