Lose the boat anchor of that OEM steel crank pulley with this 230 gram lightweight billet aluminum version. It is the lightest crank pulley out there and will allow the engine to spool up faster while reducing inertial losses caused by the overweight OEM pulley. This pulley is NOT underdrive and will therefore not underdrive the alternator and cause charging problems. For underdrive applications, check out our specially designed underdrive power steering pulley below. This pulley fits all MK4 Golf, Jetta, GLI, New Beetle, and 337 1.8T and 2.0 engines, as well as all Audi TT MK1 1.8T 180hp and 225 hp.
