This is the Short Stroke shock absorber or damper fitted to early Rolls Royce Silver Shadow and Bentley T1. Many cars have since been converted to Long Stroke Shock Absorbers (UR71744). You can check if your car still has the original short stroke shock absorber by simply lifting the bonnet (or hood). if the original hydraulic rams are still fitted to the shock absorber towers, then you have the original short stroke shock absorbers. If long stroke shock absorbers have been fitted then you will have a top plate that looks likethis and there will be no ram.
It is possible to modify the top plates and fit the later long stroke dampers but if you want to keep the car original then these are for you. You can find more related suspension parts here.
A handy fitting guide (also included with the shock absorber) is available here.
When creating the range of Prestige Parts shock absorbers we commissioned two independent companies to advise on the ideal specification for each shock absorber and the standard four-door rear shock absorber.
The Bilstein components are well regarded in the industry, having been used in popular handling packages and also as a direct replacement for the Sachs-Boge shock absorbers supplied by Bentley.
If there is a criticism of the Bilstein units, it is that they can be slightly harsh at low speeds, which is partly a function of being gas-charged as opposed to oil-filled.
The manufacturer was provided the brief to mimic the damping curve of the Bilstein units above a particular shaft speed, but allowing the shock absorber to begin opeating as slightly lower forces that that exhibited by the Bilstein. A second company was employed as technical advisory to audit the work of the manufacturer, ensuring that the end product met the agreed specifications. Samples were fitted to test vehicles to ensure that product specification transferred to comfort and handling on the road.
When it came to the short stroke front shock absorber and the rear shock absorber for convertible Corniche models, the brief was simpler, and was to mimic the damping curve of the original Sachs-Boge units. Our engineers felt that altering the specification of shock absorbers with a shorter stroke would tax the unit beyond it's ideal damping range. In addition a third company was commissioned to produce the rubber gaiters, damper stems and bushes.
