Crankshaft
Increase the engine's displacement
Maximum reliability in external applications
High wear resistance properties
Description
Athena started a partnership with ZRP, leader in the production of high quality connecting rods, crankshafts and stroker kit, to extend its offer while keeping the highest standards. ZRP Crankshafts are constructed from 4340 billet precision steel and designed carefully for optimum engine performance. The production process involves meticulous checks such as sonic tests and X-ray for a reliable finished product. Each crankshaft is also exposed to a nitride process for hardening, together with heat treatments for superior wear resistance. They all have blank holes on their surface and they’re all balanced 1 gr.cm +/- 0.1 for 4 cylinders and 2 gr.cm +/- 0.1 for 6 cylinders. All ZRP’s crankshafts are plug and play.
