Removing the OEM plastic lower bumper valance on the 2015-2019 Chevrolet Silverado 2500 / 3500 HD trucks is a proven method for improving ground clearance and fitting more aggressive wheel and tire combinations, but leaves an unattractive, gaping void in the lower middle section of the bumper.To solve this issue on customer trucks getting suspension lifts at our shop, we've developed two Lower Valance Filler Panel options for trucks with and without tow hooks. These heavy gauge aluminum panels finish off the lower center cutout in the bumper providing a more aggressive look to lifted or leveled trucks.

• This aluminum panel cleanly finishes the bottom opening of your 2015-2019 Chevy Silverado HD truck bumper when the lower plastic air dam has been removed.
• Allows for installation of more aggressive wheel and tire combinations
• Cutouts provide access and use of factory installed tow hooks
• Raw aluminum finish for Paint Matching
• Reuses Existing Factory Hardware
