❓ Frequently Asked Questions
Q1: Does this fork oil seal fit Thunderbird UCE models?
✅ Yes— Thunderbird 350/500 UCE (Thunderbird X variants) use 41 mm forks and OEM seal 594406.
Q2: Will it fit Classic, Bullet, or Meteor models?
❌ No—those models use smaller fork diameters (35–39 mm) and require a different seal.
Q3: Should I replace both seals at once?
✅ Yes—order two seals (one per fork leg) whenever rebuilding or servicing the front forks.
Q4: Can I install it myself?
Yes. Clean the slider bore, lubricate with fork oil, and gently press the seal flush into the fork leg.
Q5: Do I need dust seals as well?
🟢 Recommended—simultaneously replacing dust seals helps ensure leak-free support and prolonged fork life.
