Manufactured exclusively for Alfaholics and developed using the very latest knowledge in crank design to run safely at up to 9,500rpm! The oil gallery design has been greatly improved to provide better oil flow to the bearings at high revs. The counterweights have been optimised, both in terms of mass and design, to ensure that the piston and rod assembly is accurately counterweighted all the way to 9,500rpm. If the crank is being used in bigger bore applications, for example in single seaters, heavy metal inserts can be fitted to the holes in the webs to match the higher piston mass and maintain perfect counterweighting. The original ‘half moon’ system for locating the flywheel bolts has been replaced with direct threading of the crank using M10 bolts for improved strength. The crank is supplied nitrided.
