This billet crankshaft power pulley has a reduced diameter to minimize the horsepower robbing drag of the alternator and air conditioning compressor.
This crank pulley would not fit the 2.0L LSJ. The naturally aspirated ECOtec engines (L61 and LE5) have a 6-bolt crank, while the boosted ECOtec engines (LSJ and LNF) have an 8-bolt crank. The GMPP crank pulley is made for a 6-bolt crank. The purpose of the billet crank pulley is to withstand the rigors of racing applications that involve extended time on the rev limiter.
