Restore stability and eliminate body roll on your heavy-duty truck with the ATRO PL1147 Polyurethane Sway Bar Bushing. Proudly Made in the USA, this premium suspension bushing is specifically engineered to replace short-lived OEM rubber components on high-mileage fleets and owner-operator rigs.
Unlike standard rubber bushings that stretch, soften, and dry-rot when exposed to road contaminants, ATRO’s proprietary polyurethane compound is chemically immune to oil, grease, road salt, and environmental wear. Designed with a convenient split configuration, this bushing allows for fast, easy installation without requiring a full teardown of the sway bar assembly. Optimized for the popular Kenworth Air Glide 200 (40K) suspension, it maintains precise axle alignment, extends service intervals, and lowers your overall cost-per-mile.
Split Design for Easy Installation: Pre-slit layout allows you to slip the bushing over the bar quickly, slashing shop downtime and labor costs.
Advanced Polyurethane Technology: Engineered to handle high torsional loads without tearing, crushing, or walking out of the bracket.
Proudly Made in the USA: Manufactured to elite commercial standards for dependable long-haul performance.
Chemical & Environmental Resistance: Completely unaffected by underhood fluids, road grime, and extreme seasonal weather.
