The new Pro Race crankshaft from Spanish manufacturers Airsal is a very high quality crankshaft at the level of Malossi MHR RHQ, Metrakit Pro Race or the Polini Evolution crankshaft. The fully forged shaft 18NiCrMo5 high quality steel is hardened due to special heat treatment. The full cheek design allows higher pre-compression. The connecting rod is fully forged and hand polished to solidify the structure and has been subjected to the same hardening process as the crankshaft guaranteeing low wear in the bearings. A perfect, dynamically balanced crankshaft for heavy loads and optimum performance in high end engines.
