High quality (UK manufactured) coil valve springs to fit Norton OHV single cylinder models (ES2 and Model 18) from 1930's - 1950's as well as SOHC Norton Inter and CS1 engines from the early 1930's fitted with coil valve springs (rather than the hairpin valve spring engines). Price is for a set of 4 springs (i.e. enough for one engine).
These springs are manufactured by the same company that make our SOHC hairpin valve springs, and an original 'New old stock' pair of Terry Norton ES2 coil valve springs were used as pattern to match spring strength.
Price is for a set of 4 springs.
As well as fitting all Norton single cylinder OHV models from the 1930's - 1950's, these springs are correct for the early 1930's SOHC engine if your engine is fitted with coil valve springs, rather than hairpin valve springs. The cylinder head for the 'coil' spring SOHC engine is slightly different to the hairpin type cylinder head. Email us at firstname.lastname@example.org if you require more details
At time of writing this listing (April 2018) we are just waiting for corresponding lower and upper coil valve spring cups to be CNC manufactured. We will be offering two types - those fitted to earlier OHV/SOHC engines and those fitted to later (post 48) OHV engines. We will also be able to supply OHV valve cotters at the same time.
