8:1 Piston Set (UE46310SET)
- Rolls-Royce Silver Shadow I(Late) & II
- Bentley T1 (late) & T2
This is a set of eight forged 8:1 compression pistons, supplied complete with rings & gudgeon pins and sold with a 3 year warranty. These pistons were originally fitted to Silver Shadow and T-series from chassis numbers 22118-42000, but the increased ethanol content of modern fuels means that they may also now be fitted to earlier models with 8:1 or 9:1 compression pistons.
The Prestige Parts branded piston is a modern short skirt piston, produced using a hypereutectic forging technique. Forging provides a stronger base material for the manufacture of the piston and allows a working clearance that more closely resembles that of a cast piston. It is of a "short skirt" design which, in addition to the forging process, produces a lighter piston. The weight of each piston is matched with a limit of within 0.5 grams, helping to ensure a balanced engine. The piston rings are manufactured to the latest and most modern specifications, utilising laser technologies alongside optical and tangential tension testing to ensure each ring meets an exacting standard of material and dimensional accuracy. In short, we believe this is the best piston on the market for this application.
The Liner is UE71222X and may be ordered here. The working clearance for this piston is 0.09 mm or 0.004". Please note that the working clearance is important.
