Eagle billet 4340 crankshafts for the Nissan RB26 platform are precision-machined with knife-edged counterweights to reduce rotating mass and .125" fillet radiuses for improved strength; nitrided and micropolished finishes are applied for durability. The stroker crank option noted provides a 3.059" stroke and is intended for demanding applications where reduced rotational weight and increased strength are required, accepting narrower/chamfered bearings as specified.
