These 4 or 8-bolt Austin Healey steel crankshafts are made to the highest quality.
Manufactured from EN40B Gas Nitride Hardened steel, these cranks use the original 111.1mm stroke, which allows the standard main bearings to be used, thus no additional machining is needed to your engine block in order to fit.
We had these cranks machined to fit our rear oil seal conversion kit ENG430. Required!
Due to their strength and durability, these cranks are far stronger than the originals and will easily withstand high revs from the most demanding engines!
