3SX Underdrive Aluminum Crank Pulley 3000GT 4-Groove + Belts

Crankshafts

Fits Mitsubishi 3000GT DOHC with 4-groove serpentine belt for power steering pump
Weighs only 1.5 pounds versus stock pulley that weighs 6.7 pounds
Replacement for stock crank pulley that has smaller diameter of outer cog that drives the alternator and AC compressor - smaller diameter slows down the alternator and AC compressor by about 20% resulting in less parasiotic drag on the engine

3SX now offers our own underdrive pulley! Whats the benefit? It is made from CNC 6061 machined billet aluminum and weighs only 1 pound 6 ounces! Way less than the nearly 7-pound stock crank pulley. This means you free up horsepower to the wheels. The crank pulley is the outer pulley on the crank shaft and drives the accessories (alternator, AC compressor, power steering pump) and replacing it with a lightweight pulley is one of the most common upgrades for performance vehicles since its lighter weight reduces drag on the crank and engine, netting more power from the engine. This underdrive pulley is smaller than stock size to maximize weight reduction and reduce the speed of the alternator/AC (thus reducing drag). NOTE that this ONLY works on the DOHC engines with the 4-groove power steering pump - it will NOT work on the first year DOHC engines that have the V-belt power steering pump and it will NOT work on the SOHC 12-valve engines.
