Also known as 'Crankshaft Mallory Metal' this procedure is required when there isn't sufficient counter weighting provided on the crankshaft, for instance when changing from external balance to internal balance on a cruciform type crankshaft (American V8).

We are able to determine the required amount of heavy metal and carry out the machining process to accomodate the required heavy metal slug.

The 'slug' as its called is manufactured from compressed Tungsten particles (95%) in bar form that is then machined to the reqiured size and pressed into the crankshaft counter weight.

Tungsten has a higher density than steel 18 grams/cubic cm as opposed to steel 7.8 grams/cubic cm.
