Need better visibility when towing? This pair of black towing mirrors fits your 1999-2006 GMC Sierra 1500, 2500, or 3500 (also works on Chevy Silverado same years). They're brand new in original packaging (might come in plain box if manufacturer repackaged). These are the manual extendable type - you pull them out when towing, push back when not.

Made by carmirrorparts, these are performance parts that actually help. They're black finish, made from glass and plastic, and attach with screws (bolts included!). Each mirror measures about 14\ x 24\ x 14\ and the pair weighs 17.6 lbs. Manual adjustment means no electrical issues to worry about. They fit front left and right sides, and come with a 1-year warranty.

These replace OEM part numbers and work on both driver and passenger sides. Not universal - specifically made for these trucks. Great for towing trailers, boats, or campers when you need to see what's beside and behind you. The extendable feature gives you that extra width when you need it. Installation is straightforward if you're handy, or have your mechanic put them on. No UPC. Solid upgrade for serious hauling.
