This shock absorber for the rear is from the suspension section in the Rolls-Royce & Bentley parts catalogues for models built between 1946 to 1955.
This is a modern version of the original gland seal, which is designed to be fitted alongside all the original parts (springs, expander, etc.). An additional lip has been added, and modern materials utilised for improved sealing and longevity.
Alternatively, you may wish to purchase the full damper seal kit, which is available here.
