2637 mounts are junk. I bought two different brands. They're identical--same manufacturer, different "brands". It's not a problem with "melting", it's a problem with too-thin steel shell, and (probably) cheap rubber.My buddy installed Anchor 2637's (made in CoronaVirusLand) a couple years ago, so far they haven't melted..........
They went on a 98 Suburban.
