Performance Billet 4340 steel cranks for Honda F20c F22c crankshaft
Counterweights
Counterweights are necessary to offset the forces of the reciprocating components as the crankshaft spins. The most common is knife-edge and Pendulum Undercut counterweights.
Also, different design could be provided according to your needs.

Technical Features
Essencial Features
Racing crankshafts incorporate many of the essential features shown here to ensure
maximum durability and top performance.
Drilled crankpins are the most effective way of reducing rotational inertia in a racing
crankshaft without affecting the overall strength of individual crankpins.
Gun-drilled mains are also used to lighten a racing crankshaft.
Conventional practice incorporates oiling holes in the rod journals that are chamfered to ease
the flow of oil onto the bearing.
Note the generous fillet radius on rod journal. The radius spreads the load and removes a common point of stress fractures.
Processing
A billet crank begins with a solid billet of material weighing several hundred pounds. The setup and programming time for this procedure is lengthy and expensive.
The machining process for a billet crank is long and precise, but the result is a superior crankshaft with uninterrupted grain structure and maximum strength.
