The ATRO TH83-22089 Premium Polyurethane Torque Rod Bushing Kit (Exact Cross: Dayton 334-253) is engineered as a heavy-duty replacement for commercial truck and trailer suspension assemblies. Unlike traditional rubber kits that degrade quickly under stress, ATRO's specialized polyurethane construction offers superior chemical, load, and abrasion resistance.
This kit comes complete with premium hardware and is designed to stabilize your vehicle's torque rod function, eliminate severe axle hop, reduce road vibrations, and maintain strict suspension geometry under massive payloads. Proudly Made in the USA.
Premium Polyurethane Upgrade: Replaces factory rubber with high-strength polyurethane, providing vastly superior resilience against grease, oil, road salt, and structural tearing.
Full Installation Hardware: Comes as a complete kit including high-tensile mounting hardware (1"-14 x 7" Bolt, Locknut, and Washers) to ensure a precise, clean rebuild.
Vibration Damping: Dampens harsh chassis vibration and prevents excessive axle wrap or hop that causes costly collateral damage to neighboring axle components.
American-Made Reliability: Manufactured entirely in the USA to rigorous quality control standards, ensuring consistent performance for severe-duty fleet applications.
