Fox - Shock Piston Ring - 2.250" Bore (PTFE-Bronze / .373" W)
Precision-Fit Piston Ring
This Fox Piston Ring is engineered specifically for 2.250" bore shocks. Featuring a high-performance PTFE-Bronze composition, it ensures a tight seal against the shock body to maintain consistent damping performance and prevent fluid bypass.
Key Specs
- Bore Size: 2.250"
- Material: PTFE-Bronze
- Dimensions: .373" Width x .050" Thickness
Maintain Damping Integrity
The piston ring is the heart of your shock's damping system. Even minor wear on this ring allows pressurized oil to bypass the valving shims, leading to "faded" performance, inconsistent rebound, and a harsh ride. Replacing your piston ring during a rebuild is essential to restoring that factory-new damping feel.
Why PTFE-Bronze?
- Low Friction: The PTFE-Bronze material offers superior low-friction characteristics compared to standard rings, allowing the shock to respond faster to trail chatter.
- High-Heat Tolerance: Designed to maintain its seal under extreme temperatures, ensuring your valving works exactly as intended when the shock gets hot.
- Perfect Fit: Manufactured to specific .373" width and .050" thickness tolerances to seat perfectly in your 2.250" bore piston assembly.
Note: Ensure your shock body inner wall is clean and free of deep scratches or pitting before installing a new piston ring.
