Hot weather got you down?  This oversize "California Cooling" pulley is larger than stock.  It spins your cooling fan faster than a stock one, delivering more cooling air to your engine.  This helps with the "Freeway Flyer" transmissions that turn less RPM's on the freeway than a stock motor.  It features a hardened steel inner hub with deep spirals to re-direct oil back into your engine case and prevent oil leaks.  The deep laser etched numbers are both handsome and easy to read. Note that the larger diameter pulley requires a slightly larger belt.
