Sonnax spiral retaining ring kit 76554RK incorporates a spiral snap ring that is staked to a locking ring to ensure ring contact with groove during high-rpm conditions, eliminating blowout.

  • Wrap-around design maintains contact with groove bottom
  • Locking ring prevents spiral retaining ring expansion during high RPM
