• Chemical Resilience: Fully resistant to grease, hydraulic fluid, road salt, and environmental contaminants that typically rot rubber.

• USA Made: Proudly manufactured in the United States to ensure the highest quality control and material standards.

• Standard OD Fitment: Specifically designed for Chalmers Standard OD applications for a precise, "drop-in" fit.

Maintenance Pro-Tip

Note: Due to the specialized "Step-Down" Outside Diameter (Large: 4 5/16" to Small: 3 9/16"), ensure your torque rod eye matches these dimensions. Using Atro’s polyurethane version eliminates the need for frequent lubrication and significantly extends the interval between suspension services.
