Unit Price

Basalt-silica heat shield protects your hoses, wiring, oil cooler, transmission, differential and other components from extreme radiant heat emitted by nearby exhaust pipes or catalytic converters.

With two installation orientations, this shield accommodates small and large exhaust pipes with outer diameters ranging from 1.75" to 7.00" (44.5mm to 178mm).

The heat shield is constructed with three distinct layers for maximum heat-protection. The exterior layer is manufactured from basalt fabric, or "lava rock", and has a maximum continuous operating temperature of 700-900°C (1,292-1,652°F). Installation is provided by a ceramic middle layer. The innermost layer is composed of silica fabric, which can withstand extreme maximum operating temperatures of 1,000-1,350°C (1,832-2,462°F).

The kit includes worm clamps in two different sizes as well as 7.5" (190mm) max OD stainless steel zip ties to accommodate most pipe sizes.
