Hairpin valve spring manufactured to exactly the same specification and shape as the orignal type fitted to Norton International Model 30\40 engines.
These are manufactured by our main UK spring manufacturer, who is a reputable maker of hairpin valves springs and has made similar hairpin valve springs for other engine types. A set of original (new old stock) Terry's International valve springs was used to provide the pattern.
Photo shows new springs below and original spring at the top. Price is for a set of 4 springs - which is required for one engine
Note - we also sell the Racing International/SOHC Manx type valve spring manufactured to the same specification and shape as the orignal type fitted to Norton SOHC Manx Model 30M\40M engines - which it Item 0324. These have a fractionally smaller eye than the type shown here, meaning less reciprocating weight - either type can be fitted.
