ATRO TH50-22692 Bushing for Hendrickson Ultra Rod Primaax 321-162U

Product Overview

Eliminate axle walk-out and secure your heavy-duty suspension tracking with the ATRO TH50-22692 Premium Polyurethane Torque Rod Bushing. Proudly Made in the USA, this heavy-duty bushing is specifically engineered to replace short-lived OEM rubber components on rigorous vocational fleets and demanding long-haul rigs.

Unlike standard rubber bushings that twist, soften, and dry-rot under heavy load cycles, ATRO's proprietary polyurethane compound is chemically engineered to remain completely immune to oil, grease, road salt, and hydraulic fluids. This bushing features a non-rotating, high-durability design with a molded flange that physically prevents the bushing from walking out of the torque rod eyelet. Engineered specifically to fit Hendrickson ULTRA ROD® assemblies as well as Primaax® and Firemaax® suspensions, it delivers maximum stability and a significantly extended service life.

Key Features & Benefits

• Advanced Flanged Design: Built-in heavy-duty outer shoulder layout prevents bushing walk-out, ensuring your suspension stays locked in true alignment.

• Non-Rotating Specification: Engineered to hold structural orientation firmly without internal rotational slippage, maximizing torque arm control.

• Premium Polyurethane compound: Outlasts traditional rubber alternatives under extreme weight distribution and brutal vocational haul cycles.

• Proudly Made in the USA: Manufactured to precise commercial tolerances for dependable, heavy-duty fleet reliability.
