Unlike traditional rubber insulators that dry rot, crack, and compress over time, ATRO’s proprietary polyurethane blend offers:
Superior Durability: High resistance to oil, grease, and environmental contaminants.
Vibration Dampening: Reduces cab noise and prevents premature wear on surrounding hardware.
Maintenance Free: Once installed, these bushings are designed to last the life of the vehicle in most standard applications.
Tech Tip: When replacing hood insulators, it is highly recommended to replace them in pairs to ensure even weight distribution and alignment across the hood assembly.
