The word out on the street is rpm‘s - and rpm‘s are what you get here. POLINI has developed the HPC Racing Crankshaft. Higher compression leads to higher rpm‘s, which in turn increases your top speeds.
High end crankshaft with synthetic material element. A full circle shaft (higher pre-compression, better cylinder fill), reaches up to 16,5000 rpm‘s. High quality needle bearing: light weight betters high rotation properties. Available with 10mm and 12mm piston pins. For performance perfectionists, we recommend using the 12mm version, based on it‘s increased durability.
Available for 10 and 12mm piston pins.
SIP TIP! Don‘t forget new bearings, gaskets and oil seal rings.
ATTENTION: Must be driven with an EVO Variator P241543
