I've rebuilt my GPR damper a couple of times. They are pretty simple and straight forward. Just find the right size o-ring and you're good to go. Refilling the unit with oil is the most time consuming part. Add oil slowly and move the lever back and forth to work all the air bubbles out.

Also, changing oil viscosity just a little lighter or heavier makes a big difference in performance!
