This Snap & Zap extension set from K-Source's Fit System line is built for 2015-2020 Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs. It mounts to the factory door mirror to extend your sightline while towing a trailer, then comes back off and packs into the included storage bag when you don't need the extra width.
A straightforward way to get wider towing visibility on these GM full-size SUVs without a permanent mirror swap.
