Keep your Dyno Straps from burning through and letting the car go flying in a wall! This product offers burn-through protection for dyno tie-down straps. Made of a high-temperature resistant aluminized mylar material, the Dyno Strap Heat Guard will withstand 500°F direct heat and 2000°F of radiant heat. It measures 5” wide by 3 feet and easily slips over dyno tie-down ends and slides over strap to be positioned near the area where exhaust heat exits.
