Exhaust Bushing Mounting Kit

This exhaust bushing mounting kit is designed for heavy-duty trucks, primarily Kenworth W900 models with Aero bunks. It includes polyurethane bushings and expected mounting hardware to secure the exhaust stack, dampen vibration, and prevent metal fatigue. Bushings wear over time from heat and engine movement, leading to exhaust rattling or misalignment—replacing the kit restores quiet, solid exhaust support.
