Replaces Threaded Styles: Specifically designed to replace older, high-maintenance threaded style bushings and pins.
Superior Resilience: ATRO polyurethane maintains its shape and alignment under extreme torsional loads where rubber typically fails.
Chemical Resistance: Impervious to oil, fuel, and road chemicals, preventing the "softening" or rotting associated with standard bushings.
Maintenance-Free: Self-lubricating properties reduce friction and eliminate the need for frequent greasing.
Installation Note: To ensure a proper press-fit and avoid damage to the polyurethane material, the use of the ATRO PT00-53000 installation tool is highly recommended.
