            Beautiful Upgrade

            Intstall was a breeze. About 3hrs total. Field of view is amazing now. My truck is optioned optioned out and all features with the new mirrors work perfect. Ex power fold, auto tilt, memory etc. Not sure if they have auto dim. Mirrors appear to be at a minimum oem quality. May exceed as these feel very durable and are fairly heavy. No vibrations or excessive wind noise at highway speeds. I did drill the forth hole which definitely helps with stability. All instructions for wiring and install were easy to comprehend and not like reading a Chinese manual. Also great YouTube videos. Overall very happy and love the new look. Will be a bonus next camping season when heading down the road with the trailer. My only complaint is the price but you have to pay for nice quality things.

            Tow mirror conversion

            Amazing experience with Boost! I now have power fold tow mirrors upgraded from regular. Their videos are absolutely great walking you through the process. I was so happy, I installed their wireless phone charger upgrade this morning. Thanks Boost Team! Keep it up!!

            A little expensive but they work and that’s more than I can say about the last mirrors. The power fold option is so nice to have for driving through tight northeast towns.
