Eliminate premature suspension wear with the ATRO PL1026-HT High-Temperature Polyurethane Shock Bushing. Proudly Made in the USA, this heavy-duty bushing is specifically engineered from ATRO's proprietary high-temperature polyurethane compound.
Standard rubber shock bushings quickly degrade, crack, and soften under the intense heat generated by heavy-duty shock cycles and exhaust proximity. ATRO's High-Temp (HT) design is completely chemically resistant to grease, oil, road salt, and extreme thermal environments. Upgrading to ATRO ensures your shocks stay securely mounted, preserving ride stability and protecting your fleet from frequent replacement maintenance down-time.
High-Temperature (HT) Spec: Specially formulated to maintain structural integrity and durometer rating in extreme high-heat environments.
Premium Polyurethane Material: Offers superior tensile strength and wear resistance compared to conventional black rubber bushings.
Proudly Made in the USA: Manufactured to elite commercial standards for long-haul durability and exact fitment.
Direct Exact Cross: Designed as a precise drop-in replacement for Dayton 320-153U, Gaff 18566, and major OEM lines.
