🔧 Install Tips
- Inspect Tubes: Thoroughly clean your fork tubes. If you find rust pitting or deep scratches, these seals will fail quickly until the tube is replaced/repaired.
- Use a Driver: Use a proper fork seal driver tool (or a carefully cut PVC pipe) to press the new seals evenly into place.
- Manual Required: No instructions are included; please follow your service manual’s guide for correct disassembly and reassembly steps.
