1984-2001 JEEP CHEROKEE XJ 4 DR FIR

The Hushmat 665122 is a firewall deadener and insulation kit designed for 1984-2001 Jeep Cherokee XJ 4-door models. This kit utilizes HushMat Ultra material, a proprietary USA-manufactured chemistry that dissipates heat and insulates the interior.

It effectively reduces thermal transfer from the engine, headers, manifold, and exhaust, making the SUV interior cooler in the summer and warmer in the winter. HushMat is also proven to reduce road and exhaust noise, contributing to a more comfortable and less fatiguing ride. The material is water and weather resistant, self-extinguishing per FMVSS 302, and designed for easy peel-and-stick installation.
