Our Pistons are made specially for us by Omega, Britain's leading competition piston manufacturer. They have a dish of 6CC which will is ideal for fast road cars wanting a compression ratio higher than 100m, providing the cylinder head and block have not been skimmed.

Forged by Omega for maximum strength, RR58 grade aluminium.  These give an apporximate compression ratio of 9:5:1 when fitted in an Austin Healey with a cylinder head of 62cc as original.

Being lighter and having a better design than the original they are not only stronger for performance use but are also quieter for road use. We have used metric sizes in order to take advantage of the latest ring technology and reduce crank case pressure.

They are supplied with gudgeon pins to suit standard clamp conrods (gudgeon pins for fully floating rods are available to order).

The sizes stated are the actual bore sizes, all clearances have been allowed for on the piston.

Please note that these are supplied as a set of 4. You will need 1 1/2 sets if fitted to a Jensen.
