WHY SHOULD I PAINT MY MIRROR CAPS?

Painting your mirror caps is one of the easiest ways to elevate the look of your truck and bring the whole build together.
It gives you that clean, factory-finished aesthetic to tie your build together and stand out.

  • Sets your truck apart from the rest, elevating it beyond the typical off-the-lot look.
  • Ties together other painted or color-matched parts on your truck
  • Shows a higher level of customization and care in your build

FAQ

Yes. Our caps are compatible with OEM tow mirrors if you select the OEM option in the question asking what caps were originally on your mirrors.

The only exception to this is our mirrors do not have the cut out for the ambient air sensor equipped on diesels. The caps still clip in, you just have to relocate the sensor.

If you'd like to drill a hole in your cap for the sensor you can drill a 7/32 pilot hole and then take it to 29/64 for the sensor to clip in. Please note we are not responsible for flaking to paint or chrome caused by this, or damage from improper drilling.

Only the Black caps are textured; the rest of the options have a gloss finish.

Yes, our caps work on all aftermarket tow mirrors including those purchased on eBay & Amazon. Aftermarket mirrors need to verify if the caps are CC or non-CC (see separate FAQ) to ensure proper fitment.

You need to remove one upper cap to inspect. This takes less than 10 minutes following this video: Click Here For Video

Boost mirrors utilize different caps depending on the build. You can inspect your caps following the video by clicking HERE or you can email us your order number and we can check for you.

The paint code for your truck can be found on the service parts identification sticker in the glove box. We've attached an image depicting where the paint code is located on the sticker. The paint code can be found at location 16. If you're unsure of your paint code, simply type your vehicle's color.

  • If you select the “Paintable” option, you will receive our paintable caps, which are non-textured, so they are fairly ready for you to paint them. They will not match any vehicle straight out of the box, paint is always required.
  • If you select the “Painted” option, you will receive the caps painted from us with no additional work needed on your end. We use your vehicle's VIN and paint code to match it exactly to its factory color.

We use your vehicle's VIN and paint code to match exactly the factory color it came with. We do not offer an option to paint these in a different color than what the truck was equipped with from the factory.
