Ariel Square Four Camshaft 1960-53.
These are high quality, new camshafts. Manufactured in the UK to Ariel factory drawings and specification.
They are ground to using the cam profile with quieting ramps that Ariel used from 1953 onward for the alloy Mk2 Square Four. This can be fitted to earlier Mk1 and Iron engine Square Fours with no requirement other than to use the correct valve clearances.
