The Yokomo YR-10OA contains ten ball-seat O-rings intended for 1/10 scale formula on-road dampers. These replacement seals are supplied to refresh the ball seat area when servicing YR-10F compatible chassis, helping to restore tight sealing and preserve steady damping after reassembly.
To install, remove the shock cap and piston, lift out the worn ring from the ball seat, press the new O-ring into place taking care not to pinch it, then put the assembly back together and check for leaks. Use clean tools and fresh damper fluid to keep the seals contaminant-free.
Treat these O-rings as routine service parts: swap them during scheduled rebuilds or whenever you detect oil leakage or inconsistent shock performance. They maintain sealing integrity but do not change the damper's tuned characteristics.
