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.

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.
