SETTING BOUNDARIES Easy Ways Heat Shielding Can Improve Your Vehicle’s Performance By Dan Sanchez Pre-runner and SCORE Trophy Truck builders use various forms of heat shielding to protect surrounding components from melting or getting severely damaged. You can do the same with your daily driver by adding specific types of heat shielding products in key areas. In our case, we found the wires leading to our front locking differential were getting melted from being too close to the exhaust. We found adding high-temperature wire sleeve was an easy fix, as well as adding a small section of exhaust heat shielding to the down tube that connects to the exhaust manifold, could dramatically reduce the heat radiated from it, as well as shielding heat to the oil pan and transmission. SJ 1 From the underside of our vehicle, we found the convoluted tubing that protects the wires operating our locking differential, melted away. 2 Removing the wiring harness and pulling it out where we could access it better, we could see how heat affected a large portion of the tubing. 3 To protect the wires from any damage, we used Heat Shield Products’ Hot-Rod Sleeve that protects up to 1100-degrees F continuously and 2000-degrees F intermittent. 4 The sleeve expands to slip over the connector and we routed about three-feet of Hot-Rod Sleeve over the wiring. Then zip-tied the harness out of the way. 5 We also used Heat Shield Product’s Exhaust Wrap to shield the exhaust down tube. The product will reduce exhaust pipe heat up to 70% and is easy to install. 6 Placing the Heat Shield Exhaust Wrap around the down pipe, we used the supplied wire to wrap it around the studs on the shield and secured it in place.
