Fox - Shaft U-Cup Seal - 7/8" Shaft
Precision 7/8" Shaft Seal
This Fox U-Cup seal is engineered for 7/8" shock shafts, providing a high-pressure barrier that keeps damping oil in and contaminants out. Designed for precision fitment, it is a mandatory replacement component for any shock service to ensure long-term reliability.
Key Specs
- Part Type: Shaft U-Cup Seal
- Shaft Size: 7/8"
- Function: High-pressure fluid retention
Reliable Damping & Fluid Retention
The shaft seal is one of the most hardworking components in your shock. Constant cycling through mud, water, and ice, combined with extreme pressure changes, eventually causes this seal to harden or tear. Installing a fresh U-cup seal is the best way to prevent the dreaded "weeping" oil leak and maintain the internal pressure required for peak damping performance.
Installation Details:
- Precision Tolerances: Manufactured to exact Factory Series standards to ensure a perfect, leak-free seat on your 7/8" shaft.
- High-Performance Material: Engineered to remain flexible in sub-zero temperatures and resist wear under heavy off-road cycling.
- Service Tip: Always lightly lubricate the lip of the new seal with suspension fluid before sliding it over the shaft to prevent tearing the sealing edge during installation.
Note: This is the U-cup seal only. Always inspect your shaft for surface scoring before installing new seals to ensure a long-lasting, leak-free repair.
