Each package includes the essential components for a single spring eye:
(1) Heavy-Duty Spring Eye Bushing
(2) Precision-Fit Washers
Chemical Resistance: Impervious to oil, diesel, and environmental contaminants that rot rubber.
No-Lube Performance: Reduces maintenance downtime while eliminating "squeak" and friction.
Improved Handling: Maintains tighter tolerances for better steering response and reduced tire wear.
Direct Fit: Designed to meet or exceed OEM specifications for a seamless installation.
For a professional, damage-free seat, it is highly recommended to use the ATRO PT00-53000 Installation Tool. Using the correct tool ensures the bushing is pressed evenly, preventing premature wear or tearing of the poly material during the press-in process.
