speedometer cable protection from heat

There are wraps for the cable. Metal cables sometimes heat up just as much and cooks the grease. A longer cable and rerouting is a option. But the foil looking wraps with snaps are possibly the best bet. There are also off set adapters available. Call Summit Racing and ask for a 1:1 adapter for it. There are some that go 45 degrees and 90 degrees to change the location of the connection so the cable sits in a new location. But it sounds like a wrap is all that’s needed. Keep us posted! Good luck.
