The ZRP Brand is the subsidiary of DRAKOS ENGEERING renowned for its EXPERIENCE in the design of high-performance mechanical parts. ZRP specializes exclusively in forged engine parts such as forged Connecting rods or, like here, a Crankshaft forged in 4340 High Tensile Steel. ZRP Crankshafts are delivered factory balanced (report provided). CounterWeight Profiles in undercut minimize the Weight and therefore the rotating mass. The drilled Main Journals also contribute to the weight reduction of the ZRP Crankshaft. On the other hand, straight and chamfered oil passages optimize lubrication.
