Are your mirrors from Boost Auto?
Do you need new metal stabilization pins for the back of the glass?
You can often re-use them, but some wish to purchase new ones. If you are buying 1 piece of glass you need to purchase (3) pins. If you're buying 2 pieces of glass you need to purchase (6) pins.

Boost Auto Parts offers a full range of replacement upper glass compatible with all OEM and aftermarket Silverado and Sierra tow mirrors. Please reference the graphic to determine which glass is correct for your vehicle.

  • Glass With Backing: This is glass that comes attached to the plastic backing which will simply snap to your motor. All of the glass with backing comes equipped with defrost. If called out as signal glass, it will also have a red signal integrated into the glass.
  • Glass Only: This is just a piece of glass, nothing else. You will need to glue or tape this onto your existing backing. It does NOT come with the defrost or signal elements.

You should compare your mirror to the pictures shown in the graphic on the product page content.

We would recommend purchasing the 5" with backing and signal for those with OEM mirrors.

Alternatively, you can purchase glass only with signal cutout.

Yes, we also offer the lower glass at the below link.

All of the glass with backing does come with defrost.

The defrost is part of the backing, therefore it is NOT included if you purchase glass only.

Glass only is just a piece of glass that must be glued to your existing backing. It is a cheaper alternative to replacing the entire glass with backing.

If equipped, the signal on the glass is red. We do not offer any other color.

Unfortunately we do not offer any glass combinations not listed on this page.

The tolerance on the measurement is +/- 1/4". If your motor falls within that tolerance you should be okay.

If it's not within the tolerance, please email with pictures of your old glass (front and back) and the motor it mounts to so we can assist.

Contact us with pictures of your glass (front and back) as well as the motor. You can email

We utilize different glass depending on the build. Please measure your glass to ensure you get the proper glass.

Alternatively, you can email with your name or order number and we can let you know which glass to purchase.

If you don't know for sure, simply select the option stating "Not Boost Auto" to ensure you don't have any compatibility issues.

This fits all vehicles with 2015 style mirrors (aftermarket or OEM). Please be sure to review the graphic to ensure you get the correct glass.
